Answer 1

The correct answer regarding the energy transformations taking place in an alarm clock when it goes off is: Chemical to electrical to mechanical.

Here's the breakdown:

1. Chemical Energy: If the alarm clock runs on batteries, it would start with chemical energy stored in the batteries.
2. Electrical Energy: The chemical energy is converted into electrical energy when the battery powers the clock.
3. Mechanical Energy: The electrical energy then activates a mechanism (such as a motor or a speaker) that produces sound, which is a form of mechanical energy.

If your clock is plugged into an outlet, then it would start from electrical energy directly, but typically the most comprehensive answer that includes battery-powered clocks is Chemical to electrical to mechanical.
