Aheavy boy and a lightweight girl are balanced on a massless seesaw. if they both move forward so that they are one-half their original distance from the pivot point, what will happen to the seesaw? assume that both people are small enough compared to the length of the seesaw to be thought of as point masses. g

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.
