Question

Within the alarm clock seen here, energy is transformed. It is time to get up! The alarm clock goes off. What are the energy transformations taking place in your alarm clock?

Answer 1

An alarm clock undergoes energy transformations including electrical to mechanical, mechanical to sound, and some energy being transformed into thermal energy.

Step-by-step explanation:

In an alarm clock, there are several energy transformations taking place. First, electrical energy from the battery or power source is transformed into mechanical energy as the gears and springs inside the clockwork to turn the hands and set off the alarm. This mechanical energy is then transformed into sound energy as the alarm sounds, producing vibrations that create sound waves. Finally, some of the energy is also transformed into thermal energy due to the friction between the moving parts of the clock.

Answer 2

Step-by-step explanation:

Please see the attached image of the alarm

Options for the given question

A) electrical --> heat --> sound

B) electrical --> light --> sound

C) electrical --> chemical --> light

D) chemical --> electrical --> mechanical

Solution -

The alarm shown in this picture is a digital alarm in which the chemical cells are the major source for storing electrical energy. These chemical cells then provide stored electrical energy as chemical energy which is again converted into electrical energy and as the alarm rings, the electrical energy is converted into sound energy.

Thus, the energy transformations taking place are as follows –

electrical energy -- Chemical energy -- Sound energy.

Hence, option C is correct
