What is the difference between speed and velocity? A.
Speed measures an object's change in position, while velocity measures an object's change in position per unit time.
B.
Speed measures an object's change in position per unit time, while velocity measures an object's change in speed per unit time.
C.
Velocity and speed both measure an object's change in position, but velocity only depends upon the object's speed.
D.
Velocity measures an object's rate and direction of motion, and speed measures rate only.

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.
