A car has its 0.45m long radio antenna oriented vertically upward and is traveling at highway speeds of 70 mph. At the car's location the Earth's magnetic field has a magnitude of 0.3*10-4 T and is directed out of the ground at 35 degrees above the ground pointing Northward.
a) Calculate the range of induced emf on the antenna.
b) Specify the directions the car must travel to produce the minimum and the maximum values of that induced emf.
