Peter’s teacher tells him that he should not place his electric stereo near the edge of a pool because the water in the pool is a conductor. What does she mean when she says that the water is a conductor?

Electric charges move through the water in the pool.

Water is a type of electrical energy.

Water damages electric circuits.

Electric charges cannot flow without water.

Some of the materials for a laboratory experiment are copper wire, plastic tubing, and a pair of cotton gloves. Why is the copper wire the best electrical conductor in this group of materials?

Copper wire allows electric charges to flow easily through it.

Copper wire resists the flow of charged particles.

Copper wire can withstand very high temperatures.

How are electromagnets different from magnets?

You can turn an electromagnet on/off

What would increase the strength of an electromagnet?

Increasing the amount of current flowing through the wire

Changing the direction of the current

Decreasing the numbers of coils of wire

The diagram shows four charged objects: A, B, C, and D. Based on the diagram, which statement is true?

The electric force between A and B is greater than the electric force between C and D.

The electric force between A and B is identical in magnitude (size) to the electric force between C and D.

The electric force between A and B is smaller than the electric force between C and D.

The electric force between A and B is canceled by the electric force between C and D.

Daniel has a long piece of copper wire. He shapes the wire into a coil. What could Daniel do to cause electric current to flow through the wire?

connect the two free ends of the wire to a power source so that they form a closed path.

submerge the wire into a pan of hot water

move a bar magnet in and out of the wire coil
