A thick layer of oil floats on top of some water in a cup. If a light ray hits the boundary between the oil and water at an incident angle of 31.0 deg., and refracts into the water at an angle of 34.4 deg., what is the index of refraction of the oil, n_1? a: n_1 = 1.46
b: n_1 = 0.751
c: n_1 = 1.10
d: n_1 = 1.21

The two metal spheres in the figure are connected by a metal wire with w switch in the middle. initially the switch is open. sphere 1, with the larger radius, i'd given a positive charge. sphere 2, with the smaller radius, is neutral. then the switch is closed. afterward, sphere 1 has charge q1, is at potential v1 and the electric field strength at its surface is e1. the values for sphere 2 are q2, v2, and e2. a. is v1 < ,> , or = to v2? explain. b. is q2 < , > , or = explain? c. is e1 < ,> ,or = to e2? explain?
