Answer:
5. Amplitude.
6. 344.8 meters/second
Explanation:
5. The energy is proportional to the amplitude is all I remember. Sorry :/ Been a long time since I took these classes.
6. Traveling to the wall & back is 200m
100 + 100 = 200m total traveled
The time is 0.58s so, we can use the speed formula to solve [ s = d/t ] where s = speed, d = distance, and t = time.
s = 200/0.58
s = 344.82758
I don’t know if they’ll have you round, but I would say the speed of the sound is 344.8 m/s.
