Identify a month in which the rainfall was approximately 5 inches. Select all that apply.

Two parallel long wires carry the same current and repel each other with a force F per unit length. If both these currents are doubled and the wire separation tripled, the force per unit length becomes:

An electron goes from one equipotential surface to another along one of the four paths shown below. Rank the paths according to the work done by the electric field, from least to greatest.

A circular loop of wire is positioned half in and half out of a square region of constant uniform magnetic field directed into the page, as shown. To induce a clockwise current in this loop:  

  The electric field for a plane electromagnetic wave traveling in the +y direction is shown. Consider a point where E field is in the +z direction. The B field is:

A negatively charged particle is moving to the right, directly above a wire having a current flowing to the right, as shown in the figure. In which direction is the magnetic force exerted on the particle?

A parallel plate capacitor with plates of area A and plate separation d is charged so that the potential difference between its plates is V.  If the capacitor is then isolated and its plate separation is decreased to d/2, what happens to the potential difference between the plates?

A certain capacitor, in series with a resistor, is being charged. At the end of 10 ms its charge is half the final value. The time constant for the process is about:

Match the definition on the left with the term that most closely matches it on the right:
