work is distance * force so 15*100=1500
and to find time you know power = diastance * force / time
so 25=15*100/t
25=1500/t
25/1500=t
.016=time
The work done is 1500 Joules and the time required to do the work is 60 seconds.
The subject at hand is related to concepts in physics, specifically work and power.
To find the work done, we use the formula Work = Force x Distance. Substituting the given values:
Work = 100 Newtons x 15 meters = 1500 Joules
To find the time required to do the work, we use the formula Power = Work / Time. Substituting the given values and rearranging the formula to solve for Time gives us:
Time = Work / Power = 1500 Joules / 25 Watts = 60 Seconds

By using the relation between period and frequency, we conclude that the period of the fork is0.0023 seconds.
We know that the relation between period and frequency is:
T = 1/f
where T is the period and f is the frequency.
In this case, we know that the frequency of the fork is 440 Hz, where:
1 Hz = 1/s
Then the period of the fork will be:
T = 1/(440 Hz) = (1/440) s = 0.0023 s
Meaning that each complete vibration of the fork takes 0.0023 seconds.
