Question

11) A boy is standing next to a radio. As he moves away from the radio, which would MOST LIKELY occur? A) an increase in the speed of sound wave particles B) a decrease in the speed of sound wave particles C) a decrease in sound intensity, with respect to the observer D) an increase in sound intensity, with respect to the observer

Answer 1

It's C

Step-by-step explanation:

An observer moves toward the source, the sound intensity increases. As an observer moves away from the source, the sound intensity decreases. The speed of sound molecules is not altered. Therefore, the correct answer is a decrease in sound intensity, with respect to the observer.

Answer 2

a decrease in speed of sound waves okay my friend
