Answer 1

When an electric fan is plugged into a wall outlet, the fan blades spin as a result. What energy transformation occurred?(1 point)

Answer 2

A simple circuit is wired with a battery, a switch, and a bell. When the switch is turned on, what energy transformations will occur?

Answer 3

A woman runs as shown. What main energy conversion occurs?

Answer 4

Heated gases will rise to the top of its container. Why does this occur?(1 point)

Answer 5

Electrical energy to mechanical energy

Answer 6

Electrical energy to mechanical energy

Answer 7

When the switch is turned on in a simple circuit with a battery and a bell, the following energy transformations will occur:

1. Chemical energy in the battery is converted to electrical energy.
2. Electrical energy flows through the circuit.
3. Electrical energy is converted to mechanical energy in the bell, causing it to ring or produce sound.

Answer 8

The main energy conversion that occurs when a woman runs is the conversion of chemical energy stored in her body to mechanical energy, which is used to power her movement.

Answer 9

This occurs due to the process of convection. When gases are heated, their molecules gain kinetic energy and move faster, causing them to spread out and become less dense. As a result, the heated gases become lighter than the surrounding cooler gases, causing them to rise to the top of their container.
