Answer:
the answer would be A hope it helps.
Explanation:
Work is equal to force times distance or W = Fn x d
In this situation, you would use the following equation:
W= 200N x 50N
W= 10,000N
The man performed 10,000N of work.
B) wavelength
Notice how Z goes from one wave's crest (top) to another's crest. Wavelength can also be measured from a wave's trough (bottom) to the next one's trough.
