The wavelength of light in nanometers is 0.017 x [tex]10^{3}[/tex] nm.

We have -

d = [tex]2.25\times 10^{-6}[/tex]

n = 1 = order

θ = 15.7 degrees

We have to calculate the wavelength of light (λ) in nanometers.

Diffraction is defined as the bending or spreading of light waves as it passes through the edge of an object or through a small slit (size of slit should be very very less then wavelength of light) is called diffraction.

According to the question, we can use the following relation to calculate wavelength as -

d sinθ = nλ

λ = [tex]\frac{dsin\theta}{n}[/tex]

λ = d sinθ               (since n = 1)

λ = [tex]2.25\times 10^{-6}[/tex] x sin (15.7)

λ = 0.0079 x 2.25 x [tex]10^{-6}[/tex]

λ = 0.0177 x [tex]10^{-6}[/tex] m

We know that -

1 nanometer = [tex]10^{-9}[/tex] m

1 m = [tex]\frac{1}{10^{-9} }[/tex]

0.017 x [tex]10^{-6}[/tex] m will be equal to = [tex]\frac{0.017\times 10^{-6} }{10^{-9} }[/tex] = 0.0177 x [tex]10^{3}[/tex] nm

Hence, the wavelength of light in nano meters is 0.0177 x [tex]10^{3}[/tex] nm.

Answer:

The value of R₂ is equal to 24.75 ohms.

Explanation:

Given that,

Two resistors, R₁ and R₂, are  connected in parallel.

The equivalent resistance is 14.5 ohms

We need to find the value of R₂.

When two resistors are connected in parallel. The equivalent resistance is given by :

[tex]\dfrac{1}{R_{eq}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}\\\\\dfrac{1}{14.5}=\dfrac{1}{35}+\dfrac{1}{R_2}\\\\\dfrac{1}{R_2}=\dfrac{1}{14.5}-\dfrac{1}{35}\\\\\dfrac{1}{R_2}=0.04039\\\\R_2=\dfrac{1}{0.04039}\\\\R_2=24.75\ \Omega[/tex]

So, the value of R₂ is equal to 24.75 ohms.

Answer:

The acceleration of the bowling ball is

1.875 m/s2

0.143 A

Explanation:

The total resistance of the circuit is

[tex]r = \frac{(40)(30)}{40 + 30} + \frac{(50)(20 + 10)}{50 + (20 + 10)} \\ = 35.89 \: ohms[/tex]

so the total current is

Itotal= V/R = 9V/35.89 ohms

= 0.25 A

To find the voltage drop across the 30-ohns resistor, use

V = Itotal × (combined resistance of 40 30)

= 0.25 A × 17.14 ohms = 4.285 volts

so the current through the 30-ohm resistor is

I = (voltage drop)/30-ohms

= (4.285 V)/(30 ohms)

= 0.143 A

For a parallel circuit the voltage across each resistor is the same. Therefore, the voltage drop across the 30 Ω resistor is 9V. Then, the current through this resistor is 0.3 A.

Resistance is the hindrance to the flow of current through a circuit. It is expressed in Ohms. Resistance and current are in inverse proportion. According to Ohm's law, the product of current and resistance is the voltage across the circuit.

V = I R

There are two type of circuits parallel and series. Parallel circuits connects each components in parallel fashion where, the current through each one will be different and voltage is constant.

In a series circuit, the voltage drop across each component is different but the current is the same.

Here, the resistors are connected in a parallel fashion. Hence the voltage drop across each resistors will be 9 V itself.

then current across 30 Ω resistor is:

I = V/R

 = 9 v/ 30 Ω

 = 0.3 A.

Therefore, the current through the resistor of 30 Ω  is 0.3 A.

Answer:

When an object moves in a straight line at a steady speed, we can calculate its speed if we know how far it travels and how long it takes. This equation shows the relationship between speed, distance traveled and time taken: Speed is distance divided by the time taken.

Answer: The motion of the object will remain the same

Explanation:

Answer:

v = 16.98 km/s

Explanation:

Given that,

Distance, d = 4500 km

Time, t = 265 s

We need to find its average speed. The total distance covered divided by total time taken is called average speed of an object. So,

[tex]v=\dfrac{4500\ km}{265\ s}\\\\=16.98\ km/s[/tex]

So, the average speed is 16.98 km/s.

Answer:

The particle moves to the right when 0 ≤ t < a

Explanation:

Since at any time t≥0 its position is given by x(t) = 12(a−t)², the particle moves to the right if x(t) > 0

So,  x(t) > 0 ⇒ 12(a−t)² > 0 ⇒ (a−t)² > 0

So, (a−t)² > 0

taking square-root of both sides, we have

√(a−t)² > √0

⇒ (a−t) > 0

⇒ a > t

Since t ≥ 0 ⇒ a > t ≥ 0 ⇒ 0 ≤ t < a

So, the particle moves to the right when 0 ≤ t < a

Answer:

The speed of light in glycerol is 2.04×108 m/s .

Explanation:

The speed of light in glycerol will be 2.03 ×10⁷ m/sec. The speed of light is found as the ratio of the speed of light in air and the refractive index.

The level of bending of a light beam as it goes from one medium to another is known as the refractive index of the medium.

The frequency of the wave is given as;

[tex]\rm f = 5.09 \times 10^{14} Hz[/tex]

The refractive index of ethyl alcohol is n=1.4722

The substance's index of refraction yields the ratio of light speed in a vacuum to light speed in that medium, the speed of light is sound as;

[tex]\rm n = \frac{C}{v} \\\\ \rm v = \frac{C}{n} \\\\ \rm v = \frac{3 \times 10^8}{1.4722} \\\\ v= 20377660.00\ m/sec \\\\ v= 2.03 \times 10^7 m/sec[/tex]

Hence, the speed of light in glycerol will be 2.03 ×10⁷ m/sec.

P = m × g

P = 1000 N × 0.61

P = 610 N

Result: Its weight on Pluto will be 610 Newtons (Alternative D).

Answer

From

V=Distance/time

The distance round a circular path or Object is 2πr

so

v=2πr/T

Making T(period) subject

T=2πr/v

where v is the linear velocity.

We don't have the velocity but we can get it.

The Moon and Earth exert gravitational force on each other and the Moon is kept in Orbit by Centripetal force.

Since the Moon doesn't fly out of Orbit... it must mean that the Gravitational force being exerted on it by the Earth is equal to its centripetal Force.

Equating Both (Fg=Fc)

Fg=GMm/R²

Fc=mv²/r

GMm/R² = mv²/R

Canceling out "m" and "r" on both sides

we're left with

V²=GM/R

V=√GM/R

Where M= Mass of Earth (5.98x10^24)

R=Distance between the center of earth and the Moon

G= Gravitational Constant(Value 6.67x10^-11)

V=√6.67x10^-11 x 5.98x10^24/(3.82x10^8)

V=1021.84meters per second.

Now

T=2πr/v

=2π x 3.82x10^8 / 1021.84

T=2.35x10^6seconds

Converting to days by dividing by(24 x 3600)

You have

T=27.2days approx.

Answer:

29.7 m/s fast, velocity is 29.7 m/s

Explanation:

Applying,

v² = u²+2gs...................... Equation 1

Where v = final velocity, u = initial velocity, g = acceleration due to gravity, s = distance.

Given: u = 0 m/s (dropped from height), s = 45 m

Constant: g = 9.8 m/s²

Substitute these values into equation 1

v² = 0²+2×9.8×45

v² = 882

v = √(882)

v = 29.7 m/s.

Hence the stone will be moving 29.7 m/s fast and the velocity is also 29.7 m/s
