Question

Describe any two ways you can use vibrations to make a sound.

Answer 1

Answer:

The varying pressure on your eardrums cause them to also vibrate, and transferring this vibration through the hammer, anvil and stirrup, the signal is sent through electrical pulses to the brain, which interprets it as sound.

Explanation:

Take a rubber string stretch it tightly between two supports. Pluck the string, the string begins to vibrate. Then we will be able to hear some sound, stop the movement of the string. Even the sound also stops. From this activity we can show that the sound is produced by the vibration of material

Answer 2

Answer:

an object vibrates, cause moment in surrounding air molecules. This molecule is bump into the molecules close to them, causing them to vibrate as well. This makes them bump into more near by air molecules.This"chain reaction" movement, called sound ways, keep going until the molecules run out of energy.
