An unpolarized beam of light with an intensity of 4000 W/m2 is incident on two ideal polarizing sheets. If the angle between the two polarizers is 0.429 rad, what is the emerging light intensity

The intensity is  

Explanation:

From the question we are told that

    The intensity of the unpolarized light is  

    The  angle between the ideal polarizing sheet is  

Generally the intensity of  light emerging from the first polarizer is mathematically represented as

substituting values

Then the intensity of  incident light emerging from the second polarizer is mathematically represented by Malus law as

substituting values

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

overcharge is the right answer system
