(a) A solenoid having an inductance of 6.30μH

is connected in series with a 1.6 kΩ

resistor. If a 14.0V

battery is connected across the pair, What is the current in units of A

through the resistor at time t=1.0τL

?

(b)A certain elastic conducting material is stretched into a circular loop of 4.6 cm

radius. It is placed with its plane perpendicular to a uniform 0.5 T

magnetic field. When released, the radius of the loop starts to shrink at an instantaneous rate of 75.0cm/s

. What emf is induced in the loop at that instant in units of V
