Amagnetic field of 0.200 t exists within a solenoid of 500 turns and a diameter of 10.0 cm. how rapidly (that is, within what period of time) must the field be reduced to zero if the average induced emf within the coil during this time interval is to be 10.0 kv?

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.
