What is the source of energy for the sound from the trumpet?

• the metal shell of the trumpet

• the air inside the trumpet

• the musician blowing into the trumpet

• the light that is shining on the trumpet

Shanice assembles a battery, wire, and a light bulb as shown in the diagram. The bulb lights when she joins together the two loose ends of wire. What has Shanice demonstrated about the electrical energy needed to produce light?

• The electrical energy must travel outward from an energy source and not return to it.

• The electrical energy must travel into a device that produces light and not leave it.

• The electrical energy must travel in a closed path that includes an energy source.

• The electrical energy travels through the wires of a closed path, but not through other parts of the path.

Which event occurs because electrical energy is transformed into thermal energy?

• A lamp shines light into a room.

• A campfire heats the campers sitting around it.

• A computer displays a movie with sound.

• Cookies bake inside an electric oven.

Turning on a lamp happens in a series of quick steps. Arrange these steps in the correct order from 1 to 4, where 1 is the first step and 4 is the last step.

• 1. Someone turns the switch on the lamp from off to on. 2. The switch closes the gap in the wires of an electric circuit. 3. Electric current begins to flow through the circuit. 4. Light shines from the light bulb of the lamp.

• 1. Electric current begins to flow through the circuit. 2. Someone turns the switch on the lamp from off to on. 3. The switch closes the gap in the wires of an electric circuit. 4. Light shines from the light bulb of the lamp.
