3.3 kg block is on a perfectly smooth ramp that makes an angle of 52° with the horizontal. (a) what is the block's acceleration (in m/s2) down the ramp? (enter the magnitude.) m/s2 what is the force (in n) of the ramp on the block? (enter the magnitude.) n (b) what force (in n) applied upward along and parallel to the ramp would allow the block to move with constant velocity?

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.
