The speed of light in a piece of plastic is 1.87 × 10^8 meters per second. What is the absolute index of refraction of this plastic?
options:
1.0
1.6
0.67
1.33
Answer:
n = 1.6
Explanation:
The formula for the calculation of the absolute index of refraction is given as follows:
[tex]n = \frac{c}{v}[/tex]
where,
n = index of refraction
c = speed of light in vacuum = 3 x 10⁸ m/s
v = speed of light in the piece of plastic = 1.87 x 10⁸ m/s
Therefore,
[tex]n = \frac{3\ x\ 10^8\ m/s}{1.87\ x\ 10^8\ m/s}[/tex]
n = 1.6

Gravity is the force that objects exert on each other because of their masses. The strength of the gravitational force between two objects
depends on two factors, mass and distance. How is gravity related to mass and distance? Choose ALL the statements that apply.
If one of the masses is doubled, the force of gravity between the objects is doubled.
As distance between the objects increases, the force of gravity decreases.
As distance between the objects increases, the force of gravity increases.
The more mass two objects have, the less the force of gravity the masses exert on each other
Greater mass results in greater force.
Explanation:
Newton's law of universal gravitation states that the force of gravity affects everything with mass in the universe. Newton's law also states that the strength of gravity between any two objects depends on the masses of the objects and the distance between them
A projectile is launched from the ground with an initial horizontal velocity of 6.0m/s [right] and an initial vertical velocity of 5.0/s [up]. At what angle from vertical is it launched?
Answer:
θ = 39.8°
Explanation:
Her, we will use the trigonometric ratio of the tangent to find the launch angle of the projectile from the vertical:
[tex]tan\ \theta = \frac{v_y}{v_x}[/tex]
where,
θ = launch angle from the vertical = ?
vy = vertical component of velocity = 5 m/s
vx = horizontal component of velocity = 6 m/s
Therefore,
[tex]tan\ \theta = \frac{5\ m/s}{6\ m/s}\\\\\theta = tan^{-1}(0.8333)[/tex]
θ = 39.8°
The volume of gas decreases at constant temperature to 80% of the inital value. How does the pressure value change relative to the initial value
Answer:
The pressure value changes 400 % relative to the initial value.
Explanation:
Let suppose that the gas behaves ideally and represents a closed system, that is, a system with no mass interactions so that number of moles is conserved ([tex]n[/tex]). Since the variables involved in the isothermal process are pressure ([tex]P[/tex]) and volume ([tex]V[/tex]). Finally, the process is represented by the following relationship:
[tex]P_{1}\cdot V_{1} = P_{2}\cdot V_{2}[/tex] (1)
Where:
[tex]P_{1}, P_{2}[/tex] - Initial and final pressures.
[tex]V_{1}, V_{2}[/tex] - Initial and final volumes.
If we know that [tex]P_{1} = P_{o}[/tex], [tex]V_{1} = V_{o}[/tex] and [tex]V_{2} = 0.2\cdot V_{o}[/tex], then the final pressure of the closed system is:
[tex]P_{2} = P_{1}\cdot \left(\frac{V_{1}}{V_{2}} \right)[/tex]
[tex]P_{2} = 5\cdot P_{o}[/tex]
The pressure value changes 400 % relative to the initial value.
Two asteroids are located a certain distance away from each other. They have the same mass . The gravitational force of attraction is f . If the mass of one of the asteroids is doubled, how will the gravitational force be affected
Answer:
F' = 2F
Explanation:
The gravitational force of attraction between asteroids is given by Newton's Law of Gravitation:
[tex]F = \frac{Gm_1m_2}{r^2}[/tex]
where,
F = Force
G = Universal Gravitational Constant
m₁ = m₂ = m = mass of each asteroid
r = distance between asteroids
Therefore,
[tex]F = \frac{Gm^2}{r^2}[/tex] --------------------- eq(1)
Now, if we double the mass of one asteroid:
[tex]F' = \frac{G(2m^2)}{r^2} \\\\F' = 2\frac{Gm^2}{r^2}[/tex]
using equation (1):
F' = 2F

Explain the purpose of a three-valve manifold in closed tank level measurement installations.
Answer:
A three valve manifold serves to protect the capsule from being exposed to pressures above the acceptable range and also enables transmitter isolation from the loop of the process
In closed tank level measurement installations the pressure of the gas if presence of gas on top of the liquid will need to be taken account by the use of a reference connection from the level transmitter to the tank top. The valve used in pressure equalization is kept close when the process system is operating normally.
In the event that the transmitter is removed or put into service, it is necessary to ensure that the gas phase which is at the higher pressure is does not over-range the Differential Pressure DP capsule
Explanation:
A race car reaches the finish line and the driver slows down to come to a stop. If it takes the car 10 seconds to stop at a constant acceleration of -12mph/s. What was the car's speed at the finish line?
Answer:
53.64 m/s
Explanation:
Applying,
a = (v-u)/t............. Equation 1
Where a = acceleration of the car, v = final velocity of the car, u = initial velocity of the car, t = time.
make u the subject of the equation
u = v-at............. Equation 2
From the question,
Given: a = -12 mph/s = -5.364 m/s², t = 10 seconds, v = 0 m/s (comes to stop)
Substitute these values into equation 2
u = 0-(-5.364×10)
u = 0+53.64
u = 53.64 m/s
What is the mass of a baseball that has a kinetic energy of 105 J and is traveling at 10 m/s?
Answer:
[tex]\boxed {\boxed {\sf 2.1 \ kilograms}}[/tex]
Explanation:
Kinetic energy is the energy an object possesses due to motion. The formula 1/2 the product of mass and the squared velocity.
[tex]E_k=\frac{1}{2} mv^2[/tex]
We know the baseball's kinetic energy is 105 Joules. It is also traveling at a velocity of 10 meters per second. `
First, convert the units of Joules to make unit cancellation easier later in the problem. 1 Joule (J) is equal to 1 kilogram square meter per square second (kg*m²/s²). The baseball's kinetic energy of 105 J is equal to 105 kg*m²/s².
Now we know 2 values:
[tex]E_k= 105 \ kg*m^2/s^2[/tex][tex]v= 10 \ m/s[/tex]Substitute these values into the formula.
[tex]105 \ kg*m^2/s^2= \frac{1}{2} m (10 \ m/s)^2[/tex]
Now we need to solve for m, the mass. Solve the exponent.
(10 m/s)²= 10 m/s * 10 m/s = 100 m²/s²[tex]105 \ kg *m^2/s^2 = \frac{1}{2} m (100 \ m^2/s^2)[/tex]
Multiply on the right side.
[tex]105 \ kg *m^2/s^2 = m (\frac{1}{2} * 100 \ m^2/s^2)[/tex]
[tex]105 \ kg *m^2/s^2 = m (50 \ m^2/s^2)[/tex]
The variable, m, is being multiplied by 50 square meters per square second. The opposite of multiplication is division, so we divide both sides by that value.
[tex]\frac {105 \ kg *m^2/s^2 }{50 \ m^2/s^2}= \frac{ m (50 \ m^2/s^2)}{50 \ m^2/s^2}[/tex]
[tex]\frac {105 \ kg *m^2/s^2 }{50 \ m^2/s^2}= m[/tex]
The units of square meter per square second will cancel out.
[tex]\frac {105 }{50} \ kg= m[/tex]
[tex]2.1 \ kg=m[/tex]
The mass of the baseball is 2.1 kilograms.
Define Velocity.

Write a sine model that gives the pressure P as a function of the time t (in seconds).A middle-A tuning fork vibrates with a frequency f of 440 hertz (cycles per second). You strike a middle-A tuning fork with a force that produces a maximum pressure of 5 pascals. Write a sine model that gives the pressure P as a function of the time t (in seconds).
Answer:
P = 5sin(880πt)
Explanation:
We write the pressure in the form P = Asin2πft where A = amplitude of pressure, f = frequency of vibration and t = time.
Now, striking the middle-A tuning fork with a force that produces a maximum pressure of 5 pascals implies A = 5 Pa.
Also, the frequency of vibration is 440 hertz. So, f = 440Hz
Thus, P = Asin2πft
P = 5sin2π(440)t
P = 5sin(880πt)
