Velocity = Frequency x Wavelength
= 18 x 13 = 234 mm/s
Capable of being reversed or of reversing: as a : capable of going through a series of actions (as changes) either backward or forward

Answer:
960J
Explanation:
Given parameters:
Force = 120N
Distance = 8m
Unknown:
Work required = ?
Solution:
The work done by a body is the force applied to move a body in a specific direction.
Work done = Force x distance
Insert the parameters and solve;
Work done = 120 x 8 = 960J
