Use the information below to answer the three (3) following questions:An LC oscillator consists of a 2 × 10-5 F capacitor and an unknown inductor.  The voltage across the capacitor has a maximum value of 15 V and oscillates with a frequency of ω = 1410 rad/s. What is the maximum energy stored in the inductor?

A light ray in air enters and passes through a block of glass. What can be stated with regard to its speed after it emerges from the block?

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?

Use the information below to answer the four (4) following questions:Consider the electrical AC circuit shown.  It consists of an AC generator providing a voltage V(t) = 24 sin ((250 rad/s) t) volts, an unknown resistor, a 2 × 10-5 F capacitor, and an unknown inductor.  The impedence of the circuit is 140 Ω and the current lags the voltage across the generator by 25 degrees. What is the value of the resistor R in the circuit?

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 magnetic flux through the wire at t = 5.1 sec?
