1) A 10-ohm light bulb is connected across two long straight conducting rails that are separated by 1m. A straight conductor is placed perpendicular across the rails. A 0.2 Tesla magnetic field points perpendicular to both the rails and the conductor.

a) What is the magnitude and direction of the current in the conductor when it is sitting still?

b) What is the magnitude and direction of the current in the conductor when it is moving to the right with a velocity of 2m/s?

c) What is the magnitude and direction of the current in the conductor when it is accelerated at 0.5 m/s/s? (hint: It may depend on time.)

2) Find the power dissipated in each element in a L-C-R series circuit with R=10 ohms, L=5mH, and C=10μF.
