Use the information below to answer the three (3) following questions:A circular wire with radius r and resistance R is placed within a time-dependent but uniform magnetic field at t = 0 sec, as seen in the figure below.  The magnetic field is given by B(t) = B0 t2 and points out of the page.  Here, r = 2.7 cm, R = 2 Ω, and B0 = 8 mT/s2. What is the magnitude of the induced current at t = 3.7 sec?

Use the information below to answer the two (2) following questions:A circuit is constructed with two resistors and one inductor as shown below.  The values for the resistors are R1 = 2.5 Ω and R2 = 4.5 Ω.  The battery voltage is V = 12 V.  The switch S is initially open. After the switch has been opened for a long time, it is closed.  What is the magnitude of the voltage across L immediately after the switch is closed?
