Bonus Two spherical objects have masses of 6.3 x 103 kg and 3.5 x 104 kg. The gravitational attraction between them is 6.5 10-3 N. How far apart are their centers?

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.
