Extrasolar were searched by monitoring stars for slight dimming that might occur as unseen planets pass in front of them.
He feels a 10 N to the left force moves. Yes ,he moves.
Answer:
800J
Explanation:
Given data
Force= 100N
Distance moved= 8m
The expression for the work done is
WD= Force* distance
substitute
WD= 100*8
WD= 800Joules
Hence the work done is 800J
