In physics, force is equal to mass multiplied to acceleration. We are given that the mass is 0.25 kg and the force is 20 N.
F = ma
20 N = 0.25 kg * a
20 kg*m/s^2 = 0.25 kg * a
a = 20/0.25
a = 80 m/s^2
So the acceleration of the ball is 80 m/s^2.
Longitudinal wave is a wave in which the motion of the medium's particles is parallel to the direction of the energy transport.
Answer:
Wave frequency
Explanation:
Wave frequency is the number of waves that pass a fixed point in a given amount of time.
