Figure Q.13.33 shows a 100 g block of copper (ρ = 8900 kg/m 3 ) and a 100 g block of aluminum (ρ 2700 kg/m 3 ) connected by a massless string that runs over two massless, frictionless pulleys. The two blocks exactly balance, since they have the same mass. Now suppose that the whole systemis submerged in water. What will happen? Figure Q13.33 A. The copper block will fall, the aluminum block will rise. B. The aluminum block will fall, the copper block will rise. C. Nothing will change. D. Both blocks will rise.

Imagine you are out for a stroll on a sunny day when you encounter a lake. Unpolarized light from the sun is reflected off the lake into your eyes. However, you notice when you put on your vertically polarized sunglasses, the light reflected off the lake no longer reaches your eyes. What is the angle between the unpolarized light and the surface of the water, in degrees, measured from the horizontal? You may assume the index of refraction of air is nair=1 and the index of refraction of water is nwater=1.33 . Round your answer to three significant figures. Just enter the number, nothing else.
