PHYSICS DISCUSSION HOMEWORK DUE SUNDAY

1)Imagine a superfast fish that is able to swim faster than the speed of sound in water. Would this fish produce a “sonic boom”?

2)Use the concepts from this module to explain why flying bees buzz.

3)If the handle of a tuning fork were to be handled firmly against a table, would the sound from the tuning fork change? If so, what would change?

4)The strings of a harp have different length in order to produce different notes. However, given that the strings in a guitar have all the same length, how are the different notes produced?

5)Why is it that smaller animals (like mice and birds) tend to make higher pitch sounds while bigger animals (like bears and alligators) make deeper sounds?

6) Does it make sense why a cello make lower frequency sounds than a violin? Why?
