Answer:
4.33m
Explanation:
Power = work done/ time
work done = power × time =650 × 2 = 1300J
work done = force × distance
distance = work done/force
distance = 1300/300 = 4.33m
ocean waves because its not artificial
Answer:

Explanation:
Since the work done is same everywhere in the universe. Hence, the work done in jumping will be same for the person on moon and earth:

Answer:
The work done by the frictional force is 600J.
Explanation:
The work
done by the frictional force is
.
Now,
and
; therefore,


Hence, the work done by friction is 660J.
B is the only answer that makes sense.
