Ablender takes in 180 j of electrical energy. of the 180 j, 90 j are transformed into kinetic energy, 60 j are transformed into thermal energy, and the rest is transformed into sound.

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
