How does sound travel through a solid?

• by vibrating the molecules in the matter

• by moving in a straight line through the object

• by changing its speed as it moves through the object

• by remaining very still while traveling through the matter

Why it is easier for sound waves to move through solids than liquids?

• Molecules in liquids do not move.

• Molecules are farther apart in solids

• Molecules are closer together in solids.

• Molecules in liquids are packed too closely together.

How do foam earplugs affect the sound a person hears?

• The foam reduces the rate of sound vibration.

• The foam increases the rate of sound vibration.

• The foam reduces the amount of energy in the sound vibrations.

• The foam increases the amount of energy in the sound vibrations.

Why are humans unable to hear ultrasound waves?

• Ultrasound waves do not cause matter to vibrate

• Ultrasound waves do not have energy when traveling.

• Ultrasound waves have a higher frequency than humans can hear.

• Ultrasound waves have a larger amplitude than humans can hear
