Question

The clock will slowly become quieter and will ultimately fade from view.
The appearance of the clock will not
• change, but its sound will become
fainter.
The appearance of the clock and the sound of the clock will not change.
The clock will slowly become less visible, until you can only hear

Answer 1

As the air is removed from the space around the ringing alarm clock, the sound will become fainter. This is because sound requires a medium (like air) to travel through, and as the air is removed, there are fewer molecules to carry the sound waves. However, the appearance of the clock will not change significantly, as the visibility of the clock is not directly affected by the removal of air. Therefore, the correct answer is:

The appearance of the clock will not change, but its sound will become fainter.
