according to the equilibrium model of the timing of the tides, what should the time be between successive high tides for a dirunal tide?

Answers

Answer 1

It takes approximately 24 hours and 50 minutes for a diurnal tide to complete a full cycle and return to the same phase.

The equilibrium model of the timing of tides predicts that the time between successive high tides for a diurnal tide should be approximately 24 hours and 50 minutes. This is based on the idea that the tides are primarily caused by the gravitational forces of the Moon and Sun on the Earth's oceans.

For a diurnal tide, there is only one high tide and one low tide per day. This is because the Moon and Sun have a combined effect on the tides, and their gravitational forces act in such a way that they cancel out the effects of each other, resulting in a single high tide and a single low tide.

The Moon takes approximately 24 hours and 50 minutes to return to the same position relative to the Earth, and it is this alignment of the gravitational forces of the Moon and Sun that causes the tides. Therefore, it takes approximately 24 hours and 50 minutes for a diurnal tide to complete a full cycle and return to the same phase.

3. what are the heat transfer mechanisms involved during heat transfer in a liquid-to-liquid heat exchanger from the hot to the cold fluid?

Answers

The heat transfer mechanisms in a liquid-to-liquid heat exchanger from the hot to the cold fluid include conduction, convection, and radiation. Conduction and convection are the primary mechanisms, while radiation plays a minor role.

The heat transfer mechanisms involved during heat transfer in a liquid-to-liquid heat exchanger from the hot to the cold fluid are conduction, convection, and in some cases, radiation.

1. Conduction: This is the process of heat transfer through direct contact between the hot and cold fluids. The heat moves from the hot fluid to the cold fluid through the solid walls of the heat exchanger.

2. Convection: This mechanism occurs due to the movement of fluids in the heat exchanger. The hot fluid transfers heat to the solid walls of the heat exchanger, and the cold fluid receives the heat from the walls as it flows. The movement of fluids enhances the heat transfer rate.

3. Radiation: Although less significant in liquid-to-liquid heat exchangers, radiation is the transfer of heat through electromagnetic waves. The heat is emitted from the hot fluid and absorbed by the cold fluid without the need for direct contact or fluid movement.

What is the time taken to produce 1500J heat energy if the rate of energy transfer is 30 J/s?​

Answers

Okay, let's break this down step-by-step:

* The rate of energy transfer is 30 J/s ( joules per second )

* We need to produce 1500 J of heat energy

* So we divide the total energy needed (1500 J) by the energy transfer rate (30 J/s)

* 1500 J / 30 J/s = 50 seconds

Therefore, the time taken to produce 1500J of heat energy if the rate of energy transfer is 30 J/s is 50 seconds.

50 seconds is the answer

what is the amount of work done, in joules, to lift a basket weighing 88 newtons a total of 3 meters?

Answers

The amount of work done to lift a basket weighing 88 newtons a total of 3 meters can be calculated using the formula:

Work = Force x Distance x Cos(theta)

where Force is the weight of the basket, Distance is the height it is lifted, and theta is the angle between the force and the direction of motion (in this case, theta is 0 since the force is acting vertically upwards and the basket is also moving vertically upwards).

So, the amount of work done is:

Work = 88 N x 3 m x Cos(0)

Since Cos(0) = 1, the equation simplifies to:

Work = 88 N x 3 m x 1

Work = 264 Joules

Therefore, the amount of work done to lift the basket weighing 88 newtons a total of 3 meters is 264 Joules.

A nearby circuit element generates a magnetic field in the vicinity of the wire of B = Bxi + Byj + Bzk, where Bx = 6. 9 G, By = 2. 6 G, and Bz = 1. 1 G. A) Calculate the i component of the magnetic force Fx, in newtons, exerted on the wire by the magnetic field due to the circuit element.

B) Calculate the k component of the magnetic force Fz, in newtons, exerted on the wire by the magnetic field due to the circuit element.

C) Calculate the magnitude of the magnetic force F, in newtons, exerted on the wire by the magnetic field due to the circuit element

Answers

The i component of the magnetic force on the wire is 1.06 × 10^-13 N. The k component of the magnetic force on the wire is 6.69 × 10^-14 N. The magnitude of the magnetic force on the wire is 1.26 × 10^-13 N.

To calculate the i component of the magnetic force, we use the formula:

F = I * L x B

where I is the current, L is the length of the wire, B is the magnetic field, and x represents the cross product.

The cross product of L and B gives a vector perpendicular to both L and B, which is in the i direction. So we only need to find the magnitude of the cross product and multiply it by I to get Fx.

|L x B| = |L| |B| sinθ

where θ is the angle between L and B. Since L is in the j direction and B has i and k components, we have:

|L x B| = L * Bz = (3.8 × 10^-3 m) * (1.1 × 10^-4 T) = 4.18 × 10^-8 N

Then, Fx = I * |L x B| = (2.54 × 10^-6 A) * (4.18 × 10^-8 N) = 1.06 × 10^-13 N

To calculate the k component of the magnetic force, we use the same formula and take the k component of the cross product:

|L x B|k = |L| |B| sin(π/2) = |L| |B| = (3.8 × 10^-3 m) * (6.9 × 10^-5 T) = 2.63 × 10^-7 N

Then, Fz = I * |L x B|k = (2.54 × 10^-6 A) * (2.63 × 10^-7 N) = 6.69 × 10^-14 N

The magnitude of the magnetic force is given by,

F = sqrt(Fx^2 + Fz^2) = sqrt((1.06 × 10^-13 N)^2 + (6.69 × 10^-14 N)^2) = 1.26 × 10^-13 N

concave 4A, concave 3A and convex 1A

Answers

Below are the solutions to the selected questions:

Concave #4A

The image distance is -7.5cm, the magnification is 0.5 and the image formed is a real upright image.

Workings :

f = -5.0 cm (since it is a concave mirror)

u = -15.0 cm (since the object is placed in front of the mirror)

Using the mirror formula,

1/f = 1/v - 1/u

Substituting the values, we get:

1/v = 1/f - 1/u

1/v = 1/-5.0 - 1/-15.0

1/v = -0.2 + 0.0667

1/v = -0.1333

Taking the reciprocal on both sides, we get:

v = -7.5 cm

The negative sign indicates that the image is formed behind the mirror, which means it is a real image.

Now, we can calculate the magnification using the formula:

m = -v/u

m = -(-7.5)/15.0

m = 0.5

Concave #3A

The image distance is -4.0cm, the magnification is 0.8 and the image formed is a virtual, upright and smaller than the object.

Given:

Radius of curvature, R = -20.0 cm (since it's a concave mirror)

Object distance, u = 5.0 cm

Using the mirror formula, 1/f = 1/u + 1/v, where f is the focal length and v is the image distance, we can find the image distance:

1/f = 1/u + 1/v

1/-20.0 = 1/5.0 + 1/v

-0.05 = 0.2 + 1/v

-0.25 = 1/v

v = -4.0 cm

Since the image distance is negative, the image is virtual and upright.

To find the magnification, we use the formula:

magnification, m = -v/u

m = -(-4.0 cm)/5.0 cm

m = 0.8

The magnification is positive, indicating an upright image. The magnitude of the magnification is less than 1, which means the image is smaller than the object.

Convex #1A

The image distance is -4.0cm, the magnification is 0.8 and the image formed is a virtual, upright and smaller than the object.

Workings:

For a convex mirror, the focal length is negative, and we can use the mirror equation:

1/f = 1/do + 1/di

where f is the focal length, do is the distance of the object from the mirror, and di is the distance of the image from the mirror.

We know that the center of curvature is 60.0 cm, so the focal length is:

f = R/2 = 60.0 cm/2 = 30.0 cm

Plugging in the values, we get:

1/30.0 = 1/10.0 + 1/di

Simplifying:

di = 15.0 cm

The magnification can be found using the magnification equation:

m = -di/do

where the negative sign indicates that the image is virtual and upright. Plugging in the values, we get:

m = -15.0 cm/10.0 cm = -1.5

You may have seen ambulances on the street with the letters of the word AMBULANCE written on the front of them, in such a way as to appear correctly when viewed in your car's rear-view mirror. (See the figure.) How do the letters appear when you look directly at the ambulance (not through the mirror)?

Answers

When you look directly at an ambulance, the letters of the word "AMBULANCE" will appear reversed, or mirrored.

This is because the letters on the front of the ambulance are intentionally designed to be read in reverse when viewed in a rare-view mirror, so that drivers can quickly and easily identify the vehicle as an ambulance and make way for it to pass.

1) Here's how the letters appear when viewed directly, step by step:

2) The first letter, "A", will appear as a normal "A" when viewed directly, as there is no mirror involved.

3) The second letter, "M", will appear reversed, as the left side of the letter will appear on the right, and vice versa.

4) The third letter, "B", will also appear reversed, with the left side of the letter appearing on the right and the right side appearing on the left.

5) The fourth letter, "U", will appear normal, as it is symmetrical and looks the same from both sides.

6) The fifth letter, "L", will appear reversed, with the left side appearing on the right and the right side appearing on the left.

7) The sixth letter, "A", will again appear normal.

8) The seventh letter, "N", will appear reversed, with the left side appearing on the right and the right side appearing on the left.

9) The eighth letter, "C", will also appear reversed, with the left side appearing on the right and the right side appearing on the left.

The ninth letter, "E", will appear normal, as it is symmetrical and looks the same from both sides.

So, when you look directly at an ambulance, the letters will appear reversed for the second, third, fifth, seventh, and eighth letters.

This is because these letters are not symmetrical and have different shapes on the left and right sides, so they appear differently when viewed in reverse.

10. A roller coaster accelerates at 8.75 m/s² from rest to a final velocity of 70 m/s. How long does it
take to speed up?

Answers

We can use the formula:

v = u + at

where:
v = final velocity = 70 m/s
u = initial velocity = 0 m/s (since the roller coaster starts from rest)
a = acceleration = 8.75 m/s²
t = time

Solving for t, we get:

t = (v - u) / a
t = (70 m/s - 0 m/s) / 8.75 m/s²
t = 8 seconds

Therefore, it takes 8 seconds for the roller coaster to speed up.

how fast is moving light that has traveled through transparent glass and exited on the opposite side with respect to the incoming speed?

Answers

The light that has traveled through transparent glass and exited on the opposite side will move at the same speed as it was moving before entering the glass, but it would have traveled slower while inside the glass.

The speed of light changes when it travels through a transparent medium like glass. The speed of light in vacuum or air is approximately 299,792,458 meters per second (often rounded to 3.00 x 10⁸ m/s), but it slows down when it passes through a medium like glass. The amount of slowing down depends on the refractive index of the material, which is a measure of how much the speed of light is reduced as it passes through the material.

For typical glasses, the refractive index is around 1.5, which means that the speed of light is reduced by a factor of about 1.5 when it passes through the glass. So, if the speed of light in vacuum or air is taken as 1, the speed of light in glass would be approximately 2/3 (or 0.67) of its original speed.

When the light exits the glass on the opposite side, it returns to its original speed in air or vacuum. Therefore, the light exits the glass with the same speed it had before it entered the glass, as long as it is not absorbed or scattered by the glass.

Would the stars orbiting the center of the Milky Way behave similarly to a planet or a comit orbiting a star?

Answers

It is accurate to say that the stars in the Milky Way behave like planets orbiting a star rather than comets orbiting a star.

What is a comet?

A comet is a celestial object consisting of a nucleus of ice and dust that is surrounded by a fuzzy coma (atmosphere) and a tail.

Will the stars and comet behave similarly?

The stars orbiting the center of the Milky Way would behave more like a planet orbiting a star than a comet. This is because the stars are much larger than comets and have a more significant gravitational pull. The stars in the Milky Way galaxy orbit around a massive central black hole, which has a mass of millions of times that of the Sun. This black hole's gravitational pull is strong enough to keep the stars in orbit around it.

In contrast, comets are much smaller and have a much weaker gravitational pull than stars. They typically orbit around the Sun in highly elliptical orbits, which can cause them to be ejected from the solar system or collide with planets. The stars in the Milky Way, on the other hand, have more circular orbits around the central black hole, which keeps them in stable orbits for billions of years.

Answers

No, the heat pump cycle is not reversible.

The reversible process is an ideal process in which no energy is lost to the surroundings, and the system returns to its initial state when the process is reversed. In the given pump cycle, heat is transferred from a low-temperature reservoir to a high-temperature reservoir with the help of work input.

This process violates the second law of thermodynamics, which states that heat cannot flow spontaneously from a cold body to a hot body without any external work input. Therefore, the given pump cycle cannot be reversible.

Additionally, the efficiency of a reversible cycle is always greater than the efficiency of an irreversible cycle. In this case, the efficiency of the heat pump cycle can be calculated using the equation:

efficiency = (heat transferred - work input) / heat transferred

Substituting the given values, we get:

efficiency = (200 - 100) / 200 = 0.5 or 50%

This efficiency is less than the maximum theoretical efficiency that a reversible cycle could achieve. Therefore, the pump cycle is irreversible.

if the cat has a mass of 3.4 kg , how far to the right of sawhorse b can it walk before the plank begins to tip?

Answers

The cat can walk up to 0.617 m to the right of sawhorse B before the plank begins to tip.

To determine how far to the right of sawhorse B the cat can walk before the plank begins to tip, we need to consider the balance of forces and torques acting on the plank. Let's assume that the plank has a mass of negligible amount compared to the cat and that it is in equilibrium before the cat steps on it.

The torque caused by the weight of the cat can be calculated as the product of the weight force and the distance from the pivot point (which is at the position of sawhorse A). This torque needs to be balanced by the torque caused by the weight of the plank, which is acting at its center of mass, and the torque caused by the normal forces exerted by the sawhorses.

Assuming that the sawhorses are at the same height, the normal forces exerted by them on the plank are equal in magnitude and opposite in direction, which means that they cancel out each other's torque. Therefore, the only torque that needs to be balanced is the one caused by the cat's weight.

Using the equation for torque balance, we can write:

(distance from sawhorse B to cat's position) x (cat's weight) = (distance from center of mass to pivot point) x (plank's weight)

We know the cat's mass, which we can convert to weight using the acceleration due to gravity [tex](9.8 m/s^2)[/tex], and we can assume that the plank's weight acts at its center (which is the midpoint of the plank). We also know the length of the plank and the position of the pivot point (which is at the position of sawhorse A).

Using these values, we can solve for the distance from sawhorse B to the cat's position:

(distance from sawhorse B to cat's position) = [(distance from center of mass to pivot point) x (plank's weight)] / (cat's weight)

Plugging in the values, we get:

(distance from sawhorse B to cat's position) = [tex][(1/2 x 1.5 m) x (9.8 m/s^2 x 4 kg)] / (3.4 kg x 9.8 m/s^2)[/tex]

Simplifying the equation, we get:

(distance from sawhorse B to cat's position) = 0.617 m

(b) How far away does it land?

() How high does it travel? Cut your time in half!

Answers

A cannonball is propelled up with a velocity of 73.5 m/s at an angle of 20 degrees above the horizontal. To solve this problem, we can make usage of the kinematic equations of motion.

How long is the cannonball in the air and how far away does it land? How high is it?

(a) To find the time the cannonball is in the air, we can use the vertical motion equation:

y = vi*t + (1/2)gt²

where y is the vertical displacement, vi is the initial vertical velocity, g is the acceleration due to gravity, and t is time.

At the highest point of the cannonball's trajectory, the vertical velocity becomes 0 m/s. Thus, we can find the time it takes to reach the highest point:

vf = vi + gt

0 = 73.5sin(20) - 9.81t

t = 8.08 s

The total time in the air will be twice this value since the cannonball will take the same amount of time to reach its maximum height as it will to fall back down to its starting height. Therefore,

The cannonball is in the air for 2t = 16.16 s.

(b) To find the horizontal distance the cannonball travels, we can use the horizontal motion equation:

x = vit + (1/2)at²

where x is the horizontal displacement, vi is the initial horizontal velocity, a is the acceleration (which is 0 for horizontal motion), and t is time.

The initial horizontal velocity is given by:

vix = vi*cos(20) = 69.87 m/s

Thus, we can find the horizontal distance:

x = vix*t

x = 1125.5 m

The cannonball lands 1125.5 meters away from where it was launched.

(c) To find the maximum height the cannonball reaches, we can use the vertical motion equation with the time cut in half:

y = vit/2 + (1/2)gt²/4

y = 73.5sin(20)8.08/2 - 9.81(8.08/2)²/4

y = 587.6 m

A. The beginning of its flight.
B. The end of its flight.
C. The highest point of its flight.
D. The speed is constant throughout the flight.

Answers

A ball is thrown across the street. During its flight, the ball's speed is lowest at the highest point of its flight. The correct answer is C.

The speed of the ball is lowest at the highest point of its flight. This is because at the highest point, the ball has reached its maximum height, and therefore, its potential energy is at its highest. As the ball continues to move, it begins to fall due to gravity, and its potential energy is converted to kinetic energy. However, since the ball is moving upwards at this point, its kinetic energy is decreasing, causing its speed to decrease until it reaches zero at the highest point.

As the ball falls back down to the ground, its potential energy is converted back to kinetic energy, causing its speed to increase again until it reaches its maximum at the end of its flight. Therefore, the correct option is C, the highest point of its flight.

An epidural anesthesia block can cause a drop in blood pressure in the mother, which can in turn affect the fetal heart rate.

A blood pressure reading of 80/40 mmHg is considered low, and can indicate hypotension.

Hypotension can lead to decreased blood flow to the placenta and fetus, which can result in fetal distress.

Therefore, it is important for the provider to be notified of the low blood pressure reading and fetal heart rate, so that appropriate interventions can be implemented to address the situation.

The provider may choose to adjust the dosage of the epidural anesthesia, administer IV fluids, or consider other measures to stabilize the mother's blood pressure and fetal well-being.

While monitoring vital signs and positioning the client can also be important interventions, they are not the priority in this scenario.

Elevating the client's legs may help to increase blood flow to the heart and improve blood pressure, and placing the client in a lateral position may also help to improve blood flow and prevent supine hypotensive syndrome.

These actions should be taken after the provider has been notified and appropriate interventions have been implemented.

calculate the current flowing through the heater and determine how much power the heater will provide

Answers

In the below given conditions the current flowing through the heater would be 12 amps and power provided by the heater would be 1440 watts.

To calculate the current flowing through the heater and determine the power it will provide, we need to know the voltage and resistance of the heater.

Let's assume that the voltage is 120V and the resistance is 10 ohms.

Using Ohm's law, we can calculate the current as I = V/R, which gives us 12 amps.

To determine the power provided by the heater, we can use the formula P = VI, where P is the power, V is the voltage and I is the current.

Substituting the values, we get

P = 120V x 12A = 1440 watts.

Therefore, the heater will provide 1440 watts of power and the current flowing through it will be 12 amps.

It is important to note that these calculations are based on the assumptions made about the voltage and resistance of the heater. Actual measurements may vary and should be taken for accurate results.

if a person applies 750 n of force to move an object 10 m, and they apply this force for 5 s, what is their power output?

Answers

The person's power output is 1500 Watts. This means that they are transferring energy at a rate of 1500 Joules per second.

Power is defined as the rate at which work is done or energy is transferred. In this scenario, the person applies a force of 750 N to move an object 10 m, which results in the transfer of 7500 J of energy.

Since this force is applied for a duration of 5 s, the person's power output can be calculated as follows:

Power = Energy / Time

Power = 7500 J / 5 s = 1500 Watts

This calculation shows that the amount of power generated depends on both the force applied and the duration for which it is applied. Understanding power is important in various fields, including physics, engineering, and athletics.

a certain rifle bullet has a mass of 8.37 g. calculate the de broglie wavelength of the bullet traveling at 1793 miles per hour.

Answers

The de Broglie wavelength of the bullet traveling at 1793 miles per hour is approximately 9.90 x 10^-37 meters.

To calculate the de Broglie wavelength of the rifle bullet, we can use the formula:

λ = h / p

where λ is the de Broglie wavelength, h is the Planck constant (6.626 x 10^-34 J*s), and p is the momentum of the bullet. To find the momentum of the bullet, we can use the formula:

p = m * v

where m is the mass of the bullet (8.37 g = 0.00837 kg) and v is the velocity of the bullet in meters per second. First, we need to convert the velocity of the bullet from miles per hour to meters per second:

1793 miles/hour * 1609.34 meters/mile / 3600 seconds/hour = 800.1 meters/second

Now we can calculate the momentum of the bullet:

p = 0.00837 kg * 800.1 m/s = 6.703 k g m / s

Finally, we can use the momentum to calculate the de Broglie wavelength:

λ = 6.626 x 10^-34 J*s / 6.703 kg m/s = 9.90 x 10^-37 meters

Therefore, the de Broglie wavelength is approximately 9.90 x 10^-37 meters.

your spaceship is approaching a ring of asteroids. the trajectory of the ship coincides with the line perpendicular to the plane of the ring and passes through its center. consider that the asteroids are evenly distributed in the ring and the ship is close to the center of the ring. how does the gravitational force exerted by the ring on the ship change?

Answers

As the spaceship approaches and passes through the center of the asteroid ring, the gravitational force on the ship increases due to the reduced distance between them.

How gravitational force exerted by the ring on the ship change?

The gravitational force between two objects is dependent on their masses and the distance between them. When the spaceship is far away from the ring of asteroids, the gravitational force exerted by the ring on the ship is relatively weak due to the large distance between them. However, as the spaceship approaches the center of the ring, the distance between the ship and the asteroids in the ring decreases, resulting in an increase in the gravitational force. This increase in gravitational force is proportional to the decrease in distance between the two objects. As the spaceship continues to move towards the center of the ring, the gravitational force exerted by the ring on the ship will continue to increase until it reaches its maximum when the ship is at the center of the ring.

a hair drier uses 8 a at 114 v. it is used with a transformer in england, where the line voltage is 237 v. what should be the ratio of the turns of the transformer (primary to secondary)?

Answers

To determine the ratio of turns of the transformer, we can use the principle of conservation of power, which states that power in equals power out in an ideal transformer.

The power input to the hair dryer is:

P = VI = (8 A)(114 V) = 912 W

The power output of the transformer should be the same as the input power, so we can use this equation to find the current in the secondary circuit:

P = VI = (I_s)(237 V)

where I_s is the current in the secondary circuit. Solving for I_s, we get:

I_s = P/V_s = (912 W)/(237 V) = 3.85 A

Now we can use the turns ratio equation to find the ratio of the turns in the transformer:

N_p/N_s = V_p/V_s = (114 V)/(237 V)

where N_p and N_s are the number of turns in the primary and secondary coils, respectively. Solving for N_p/N_s, we get:

N_p/N_s = 0.481

Therefore, the ratio of turns in the transformer should be approximately 0.481.

earth's strong magnetic field indicates that the core is made of iron because the material in the core would have to be

Answers

Earth's strong magnetic field indicates that its core is made of iron due to several factors.

Firstly, iron is a highly magnetic material that can generate a significant magnetic field when it's in motion. In the Earth's core, the liquid outer core, which consists primarily of molten iron, flows around the solid inner core, also largely composed of iron.

This motion creates a self-sustaining dynamo effect, resulting in the generation of the Earth's magnetic field.

Secondly, the Earth's density distribution supports the presence of iron in the core.

The high density of the core, measured through seismic data, can only be explained if it's composed of heavy elements such as iron, combined with some lighter elements like nickel and sulfur.

In conclusion, the presence of iron in the Earth's core is supported by the strong magnetic field and the density distribution of our planet.

The molten iron in the outer core and the solid iron in the inner core plays a crucial role in generating and maintaining the Earth's magnetic field.

Wo thin uniformly charged rods, each with length L and total charge +Q, are parallel and separated by a distance a. The first rod has one end at the origin and its other end on the positive y-axis. The second rod has its lower end on the positive x-axis



Determine the x-component of the differential force dF2 exerted on a small portion of the second rod, with length dy2 and position y2, by the first rod. (This requires integrating over differential portions of the first rod, parameterized by dy1. )

Answers

The x-component of differential force is, dF2x = kQ²/L² [1/(y2-a) - 1/(y2+a-L)].

Let's consider a small segment of the second rod, with length dy2 and position y2. We want to find the x-component of the differential force dF2 exerted on this segment by the first rod.

The x-component of the electric field vector at the position of the segment is given by the product of the total electric field and the cosine of the angle between the electric field vector and the x-axis.

The total electric field at the position of the segment is given by the integral of the electric field due to the first rod over all its elements dl, which are parameterized by dy1:

E = [tex]\int k\lambda \dfrac{1}{((y_2-a)^2+y_1^2)^{1/2}} cos\theta dx_1[/tex]

where λ1 is the linear charge density of the first rod, θ is the angle between the line connecting the element dl of the first rod and the position of the segment, and dx1 is an element of length along the first rod.

Using the geometry of the problem, we can express cosθ in terms of y1, y2, a, and L:

cosθ = (y1(L-y2))/[(y2-a)²+y1²]^(1/2)L

Substituting this expression into the integral,

E = [tex]k\lambda_1 L\int dy_1 \dfrac{(y_1(L-y_2))}{[(y_2-a)^2+y_1^2]^{3/2}}[/tex]

Integrating this expression over the length of the segment, we get the x-component of the differential force dF2:

dF2x = [tex]\int Edq 2 cos\theta[/tex]

where dq2 is the charge on the segment:

dq2 = λ2dy2 = Q/L dy2

Substituting the expressions for E and cosθ, and performing the integration, we get:

dF2x = [tex]\dfrac{kQ^2}{L^2} \int dy_1 \dfrac{y_1(L-y_2)}{[(y_2-a)^2+y_1^2]^{3/2}}[/tex]

This integral can be evaluated by making the substitution u = y2-a, which gives:

dF2x = kQ²/L² [1/(y2-a) - 1/(y2+a-L)]

In Young's experiment, light from a red laser (wavelength 700 nm) is sent through two

slit. At the same time, monochromatic visible light with another wavelength passes through the same

apparatus. As a result, most of the pattern that appears on the screen is a mixture of two colors; however, the

center of the third bright fringe of the red light appears pure red. What are the possible wavelengths of the

second type of visible light?

Answers

In Young's experiment, the pattern that appears on the screen is a result of interference between two sets of waves that are diffracted through two slits.

The location of the bright fringes in the pattern depends on the wavelength of the light used. This means that the path difference between the waves that interfere to produce this fringe is an integer multiple of the red light's wavelength (700 nm).

ΔL = mλ_red = nλ_other

where ΔL is the path difference between the waves, m and n are integers, λ_red is the wavelength of the red light, and λ_other is the wavelength of the second type of visible light.

Solving for λ_other, we get:

λ_other = (m/n) λ_red.
