At high velocities, the drag force is seen to depend on the square of the velocity of the object. suppose you are told that the terminal velocity for a fast moving mass of 0.038 kg is 16 m/s. what is the drag coefficient for this v2-dependent air resistance?

An ideal polarizer with its transmission axis rotated 30 degrees to the vertical is placed in a beam of unpolarized light of intensity 10w/m^2. after passing through the polarizer, what is the intensity of the beam? a. 8.7 w/m^2 b. 7.5 w/m^2 c. 5.0 w/m^2 d. 10 w/m^2 e. 2.5 w/m^2
