A) a magnet falls through a loop of wire with the southpole entering first. as the south pole approaches the loop, what isthe direction of the induced current in the loop (as veiwed fromabove, looking down on the magnet)? b) a magnet falls through a loop of wire with the southpole entering first. after it has fallen all the way through, sothat the north pole end is moving away from the loop, what is thedirection of the induced current in the loop (as veiwed from above, looking down on the magnet)?

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius ν
=0.381meters and mass ν=3.1νν. initially ν"is on the ground and ν#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of ν#just before it strikes the ground. assume the pulley bearing is frictionless.
