Three nested coffee filters fall, quickly reaching a terminal speed of ~ 1.7 m/s. If the air resistance force on a single falling coffee filter was F1, how large is the air resistance force on the three falling filters? 1) F1 2) 3*F1 3) (1/3)*F1 4) not enough information

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.
