20. This is a transverse wave.
21. a is a Crest
b is the wavelength
c is the amplitude
d is the trough
e isthe amplitude
f is the wavelength
g is time
Explanation:
Answer:
v = 16 m/s
Explanation:
It is given that,
Acceleration of a particle along x -axis is 
At t = 0s, its velocity is 6 m/s
We need to find the velocity at t = 4 s
It means that the initial velocity of the particle is 6 m/s
Let v is the velocity at t = 4 s
So,
v = u + at

So, the velocity at t = 4 s is 16 m/s.
