Question 12

What causes the speaker to vibrate?

Accepted Answer

The speaker needs a force such as being plugged in or turned on to cause vibration.

Answer

The sound makes it vibrate.

Question 13

When the speaker vibrates, why do the air particles move?

Accepted Answer

The air particles move because the speaker pushes on the air particles.

Answer

The air particles move because of the sound.

Question 14

How do the air particles between the speaker and sound detector move?

Accepted Answer

The particles vibrate back and forth.

Answer

The particles travel across the whole space to the sound detector.

Question 15

What moves across the whole sound wave?

Accepted Answer

Energy

Answer

Air particles

Question 16

How is energy transferred through the medium?

Accepted Answer

The air particles collide into each other over the space between the speaker and the sound detector.

Answer

The speaker sends out energy.

Question 17

If the sound had a large amplitude, how would the particles move?

Accepted Answer

They would vibrate back and forth farther away from the speaker.

Answer

They would vibrate back and forth closer to the speaker.

Answer

They would vibrate back and forth faster.

Answer

They would vibrate back and forth slower.

Question 18

If the sound had a low pitch, how would the particles move?

Accepted Answer

The particles would vibrate back and forth slower.

Answer

The particles would vibrate back and forth farther from the speaker.

Answer

The particles would vibrate back and forth closer to the speaker.

Answer

The particles would vibrate back and forth faster.

Question 19

Why does the sound detector vibrate?

Accepted Answer

It vibrates because the air molecules are pushing on the sound detector.

Answer

It vibrates because the speaker is playing sound.

Question 20

How would hair cells react to a low pitch sound?

Accepted Answer

The hair cells would vibrate slowly.

Answer

The hair cells would vibrate quickly.

Answer

The hair cells would move back and forth farther.

Answer

The hair cells would move back and forth less far.

Question 21
