Answer:
18,850 Hz
Explanation:
We need to figure out the wavelength of the sound wave.
Thus,
Wavelength = 1000 * Lowest Amplitude Wave
Wavelength = 1000 * 2.0 * 10^(-5)
Wavelength = 0.02
Or,

Now, we need the frequency of this wave. It goes by the formula:

Where
f is the frequency in Hz
v is the speed of sound in air (to be 377 m/s)
is the wavelength (we found to be 0.02)
Substituting, we find the frequency:

The wave has frequency of 18,850 Hz
Your answer would be B because potential energy is an object's potential to move while kinetic energy is the energy of the object in motion. So if the apple is falling, then the potential energy would decrease and its kinetic energy would increase.
Hope this helps :)
