Nina [5.8K]

Answer:

The intensity of the light that passes through a polarizer is 0.55I₀.

Explanation:

The intensity of the light that passes through a polarizer can be found using Malus's law:  

I = I_{0}cos^{2}(\theta)

<u>Where</u>:

I: is the intensity of the light that passes through a polarizer

I₀: is the initial intensity

θ:  is the angle between the light's initial polarization direction and the axis of the polarizer = 42°  

I = I_{0}cos^{2}(\theta) = I_{0}cos^{2}(42) = 0.55*I_{0}

Therefore, the intensity of the light that passes through a polarizer is 0.55I₀.

I hope it helps you!

Vera_Pavlovna [14]
If the collision is elastic, there is no loss in kinetic energies, which means that the total energies before and after impact are the same.  So no need to worry about final velocities.

Final energy
= initial energy
= (1/2) (7.20*2.00^2+5.75*(-1.30)^2)
=19.26 joules

Answer: the total kinetic energy is 19.3 J. after collision.
