The amplitude of a sound wave is related to which property?
a. speed
b. volume
c. pitch
d. wavelength

B

Explanation:

The higher the volume, the higher the amplitude of the sound wave. This is because the sound wave is being converted to electricity. The higher the vibrations the higher the current it is induced. Changes in the amplitude of a particular wave do not change its wavelength or frequency. This is observable in an oscilloscope.

before we can answer, we have to see the choices that are printed there with the question.   that's the only way we can point you to the correct one.

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s
