Question

The power of a crane is 25,000wat.calculate the work done by it in 4 seconds

Answer 1

Answer:

Explanation:

power  = W/t

Power= 25000 watts

time = 4 seconds

Now,  power x time= work done =  25000 x 4 = 100000 joules

Answer 2

given,

power (P)= 25,000watt

time (t) = 4 seconds

we have,

P = w/t

w = P × t

w = 25,000 × 4

w = 100000watt/ sec

w = 10⁵watt/s
