Answer :
Final answer:
The object most likely to cause a sound wave is a hammer hitting a metal cup because the impact creates vibrations that produce sound. Other objects listed do not create sound waves when stationary. Sound waves are generated by vibrating objects.
Explanation:
Identifying Sound Wave Sources
Sound waves are created when an object vibrates, causing the air around it to move and create pressure waves. In the options provided, the object that would most likely cause a sound wave is:
- A hammer hitting a metal cup.
When the hammer strikes the metal cup, it creates vibrations in the cup, which then causes the surrounding air to vibrate as well, producing sound waves. The other options, such as a drill laying on its side, a nail stuck into a piece of wood, and a wrench locked in place around a bolt, do not inherently cause vibrations that would result in sound waves being produced. While these objects can be involved in processes that make sound (like using the drill or striking the nail), they are not actively generating sound waves when they are at rest or secured in place.
