Q1. An underwater diver sees the sun 56 above parallel.
How high is the sun above the horizon to a fisherman in a boat above the diver?
Q2. You have a hand-crank generator with a 100-turn coil (each turn having an area of 0.0500 m2), which can spin through a uniform magnetic field that has a magnitude of 0.0500 T. You can turn the crank at a maximum rate of 3 turns per second, but hand crank is connected to the coil through a set of gears that makes the coil spin at a rate 6 times larger than the rate at which you turn the crank. What is the maximum emf you can expect to get out of this generator?
