Question

Answer the following questions briefly:
1. Suppose you are on a pleasure trip to the moon and a hammer drops out of your hand on a metal plate. Will you hear the sound?
2. State the range of audible frequencies of humans. ​

Answer 1

Answer:

1. No

2. 20 Hz to 20 kHz

Explanation:

1. Moon has no atmosphere. Sound needs a medium to travel. Earth has air,         so we can hear sounds. If their would be no air, we'll be unable to hear sounds. There is no air on moon. So, we cannot hear any sound on the moon, may it be the sound produced on your hand hitting a metal plate.

2.Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz. (Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some high-frequency sensitivity as they mature; the upper limit in average adults is often closer to 15–17 kHz.)
