A simple circuit has a 2 ohm resistor in series with a 5 ohm resistor. If 3 amps of current pass through the circuit, this is the amount of power.
What is 63 W? Remember that resistance in a series circuit adds, so the resistance in this circuit is 7 ohms and P = I^2 R

This physics term describes the behavior of light as it passes from one medium to another. AND explain specifically what happens when light (incident at some angle moves) from less dense to more dense AND more dense to less dense.
What is refraction? What is rotates or bends towards the normal in the more dense material? What is rotates or bends away from the normal in the less dense material? Bonus Question: as a light passes from more dense to less dense does it always pass through? If not when will it not pass through?

The particles in the medium swish back and forth in a direction parallel to the direction of energy transfer. This wave is called
What is a longitudinal wave?

As you move closer to a proton this happens to the electric field.
What is the electric field increases exponentially? or What is the field increases by the inverse squared law?
300
A charged particle is moving perpendicularly between the poles of a horseshoe shaped bar magnet. If the magnetic field was tripled, this describes the change in force that the charge will experience.
What is the force will increase by a factor of 3? Bonus: what would happen if the charged particle was moving parallel to the magnetic field and the same change was made?

A simple circuit is made up of a 5.0 ohm resistor and a 7.0 ohm resistor in parallel. The EMF is 120V, this describes the amount of power.
What is 4.9 x 10^3 W? remember that the resistance in a parallel circuit is the inverse of the sum of the inverses so in this case the resistance is about 2.9 ohms. and P = V^2/R

600 Joules or work is required to move a charge of +5.0 x 10^-6 microcoulombs of charge through an electric field. This is the magnitude of the electric potential between its starting and ending points.

This describes how a magnet can be damaged AND what happens if the magnet is cut into two pieces.
What is heating and dropping will make the domains random? AND What is cutting a magnet in half produces two smaller magnets?
400
A circuit has a 10 ohm resistor in series with a branch that has 2 resistors in parallel with one another (a 5 ohm resistor and a 3 ohm resistor). This describes the equivalent resistance of the circuit.
What is 11.2 ohms? (in the parallel branch the resistance is 1.2 ohms we add this to the 10 ohms to get our total or equivalent resistance)

The electric field between two protons is 7.0 N/C. This is the magnitude of the force between them.
What is 4.375 x 10^19 N? or What is 4.4 x 10^ 19 N? (recall that Electric Field due to a source charge = Force between the charged particles / amount of charge "on" the source)
