What fundamental frequency would you expect from blowing across the top of an empty soda bottle that is 24 cm deep

708.3 Hz

Explanation:

For an open-air column, like the empty can, the fundamental frequency is given by

where

v = 340 m/s is the speed of sound

L is the length of the column

In this problem, the length of the bottle is

L = 24 cm = 0.24 m

Therefore, the fundamental frequency is

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
