Question

Tommy wakes up in the morning to his alarm clock at 7:00 a.m. every day. The alarm clock is connected to a wall outlet. Which statement best describes the energy transformation that is happening in the alarm clock?

The alarm clock is producing electrical energy, and the electrical energy is being transformed into light and sound energy.
Electrical energy is flowing through the wires into the alarm clock. The electrical energy is being transformed into sound energy by the buzzer.
Electrical energy is being produced by the alarm clock. The electrical energy is being transformed into sound energy by the buzzer and into light energy by the light bulbs.
Electrical energy is flowing through the wires into the alarm clock. The electrical energy is being transformed into heat energy by the buzzer and into light energy by the light bulbs.

Answer 1

The statement that best describes the energy transformation that is happening in the alarm clock is "Electrical energy is flowing through the wires into the alarm clock. The electrical energy is being transformed into sound energy by the buzzer"

ENERGY TRANSFORMATION:

• Energy exists in different forms and can be transformed from one form to another.

• According to this question, the alarm clock being described is plugged to a wall outlet, meaning that electrical energy is flowing through the wire into the alarm clock.

• The alarm clock produces a buzzing sound as a result of this energy flow.

• Therefore, statement that best describes the energy transformation that is happening in the alarm clock is "Electrical energy is flowing through the wires into the alarm clock. The electrical energy is being transformed into sound energy by the buzzer".
