Work done is the distance a force acts over.
So, the work done here is 9.0N * 3.0m = 27 J
Answer:
1500 m/s
Explanation:
Recall that for a wave,
Speed = frequency x wavelength
here we are given frequency = 500 Hz and wavelength = 3m
simply substitute into above equation
Speed = 500 Hz x 3m
= 1500 m/s
Answer:
A, C
Explanation:
It can be found in objects like a swing. It creates kinetic energy when it is coming back or going away, while moving.
B. 1520 is the difference between their weights.
