D. The maximum electromotive force induced in the coil is determined as 3,200 V.

<h3>Maximum electromotive force induced in the coil</h3>

emf(max) = NAB/t

where;

  • N is number of turns
  • B is magnetic field
  • A is area of the coil
  • t is time

Substitute the given parameters and solve for emf

emf(max) = (150 x 0.042 x 0.86) / (1.7 x 10⁻³)

emf(max) = 3,187.1 V

emf(max) ≈ 3,200 V

Thus, the maximum electromotive force induced in the coil is determined as 3,200 V.

a fast charged particle passes perpendicularly through a thin glass sheet of index of refraction 1.5. The particle emits light i
NeX [460]

The minimum speed of the particle is the Speed of light in glass is c/μ=2×108m/s.

<h3>Why is the refractive index important?</h3>

The higher the refractive index the slower the light travels, which causes a correspondingly increased change in the direction of the light within the material. What this means for lenses is that a higher refractive index material can bend the light more and allow the profile of the lens to be lower.

Refractive index values are usually determined at standard temperature. A higher temperature means the liquid becomes less dense and less viscous, causing light to travel faster in the medium.

A car with a mass of 1.2 x 10^3 kilograms starts from rest and attains a speed of 20 meters/seconds in 5 seconds. What net force
muminat

The mass of the car [m] = 1.2×10^3 kg.

The initial speed of car[u]= 0 m/s

The final speed of car [v]= 20 m/s

We are asked to calculate the force required to increase the speed from 0 to 20 m/s.

The momentum of a substance is defined as product of mass and velocity.

Mathematically momentum p=m×v   [Here m is the mass]

From Newton's second law we know that-

                       F=\frac{dp}{dt}

                       F=\frac{mv-mu}{t}     [here t is the time]

                              = \frac{1200*20-0}{5}\ N

                              =\frac{24000}{5} \ N

                              =4800\ N

                              = 4.8*10^{3} \ N      [ANS]

Hence the correct answer to the question is C.
