Mass spectrometry.....identifies dyes on nylon
☺☺☺☺
You could use the formula
W=Fd
F(force)=20N
D(distance/displacement) =15m
W=(20N)(15m)
W= 300 J
Explanation:
period of pendulum = time taken for 1 oscillation = time taken for 1 complete back and forth vibration
q1 ans is given in question its 1.5 sec
q2 ans is 1.5 sec longer than 1 sec period
The work done by a system on a different body is equal to the product of the force exerted and the distance that the body has move in parallel to the force exerted. In this item, we have to determine first the distance and multiply it with the given force equal to 750N.
