Textbook Question
Chapter 36, Problem 2PLA
For an inductor in a series alternating current circuit, the phase relationship between the current in the inductor and the voltage across the inductor is (a) the current leads the voltage by 90°; (b) the voltage leads the current by 90°; (c) the current is in phase with the voltage; (d) the current is at some phase angle ϕ relative to the voltage (ϕ is dependent on the circuit parameters).

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.
