Answer: two waves with identical crests and troughs meet
Explanation:
My teacher gave me the answer
Hello! Assuming that the only force acting on the mass is 30N...
Fnet = 30N
Fnet = ma (mass x acceleration)
ma = 30N
a = 30N / m
a = 30N / 7kg
a = 4.2857 m/s^2
a = 4 m/s^2
I hope this helps!
D, as the others will result in the likelihood of the particles colliding decreasing
