Calculate the power in
operation when a force of 10N
moves distance of 5m at a rate of
2secs.
A. 25W
B. 50W
C. 5W
D. 100W
The power can be calculated using the formula:
Power = Work/Time.
Work is equal to force multiplied by distance, so:
Work = force * distance = 10N * 5m = 50 Nm.
Time given is 2 seconds.
Power = 50 Nm / 2s = 25W.
Therefore, the correct answer is A. 25W.
To calculate the power in this operation, we can use the formula:
Power = Work / Time
First, let's calculate the work done:
Work = Force * Distance
Work = 10N * 5m
Work = 50 Joules
Now, let's calculate the power:
Power = Work / Time
Power = 50 Joules / 2 seconds
Power = 25 Watts
Therefore, the answer is A. 25W.
