Inside a light bulb is a wire. When electric energy travels through the wire, it transforms into heat energy and light energy. Which pair of sentences explains what happens if the wire breaks?

• The wire is part of the electric circuit. The electric current will not flow if it breaks.

• The wire is not part of the electric circuit. The electric current will continue to flow, but the bulb will not light.

• The wire is not part of the electric circuit. The electric current will flow, but the bulb is burned out.

• The wire is not part of the electric circuit. The electric current will flow, but the bulb is burned out.

Look at the picture. What is the best evidence that the source of the phone’s electric energy is a battery?

• The phone has a switch, earphones, and a plug.

• The phone produces heat, sound, and light.

• The phone has a switch, wires, and can be opened.

• The phone produces positive and negative charges.

When the window is closed, the switch on the electric circuit of the alarm is moved to the "off" position. When the window is opened, the switch on the electric circuit of the alarm is moved to the "on" position. Which pair of sentences describes how the system works?

• When the window is opened, it stops the flow of current in the electric circuit. Stopping the current flow changes the energy to sound energy.

• When the window is opened, it starts the flow of current in the electric circuit. Electric energy is changed into sound energy.

• When the window is closed, it stops the flow of current in the electric circuit. Mechanical energy is changed into sound energy.

• When the window is closed, it starts the flow of current in the electric circuit. Mechanical energy is changed into sound energy.
