Answer:
Power of the man is 132.9 W.
Explanation:
Given that,
Work performed by the man is 2525 J
Time for which the work is performed is 19 second
To find :
Power of the man
Solve :
Let P is the power of the man. The total work done divided by time taken is called the power of an object. Its formula is given by :
or
Therefore, the power of the man is 132.9 W.
B
Answer: -5×10-3
E=kq/r
1km = o.621371 mile
1.609 kilometers equal 1 mile. The kilometer is a unit of measurement, as is the mille. However, a mile is longer than a kilometer.
Acceleration = Change in velocity / time taken
= (5 - 15) / 2
= -5 ms^-2
