Astudent hits a drum with two different forces. draw the two different longitudinal waves being sure to label the characteristic of the wave that increases

This picture explains it all
Other than that here is an explanation
As force increases the amplitude increases
Amplitude is the maximum displacement of particles from mean position.
The frequency and period stays same as the speed at which the person hits the drums is same

Hello how was your day? ? i hope it was good

It may possibly be c i think |-/
