If the motor is used for 30 s, how much work does it do? (Power: P = W/t)

Answer 1

Answer:

answer will be 30

Explanation:

here, power=900W

time. =30 s

Power(P)= W/t

in here P= 900/30

30 is the answer

Answer 2

Answer:

Please mark my answer Brainliest

Explanation:

Since, P = W/t

So, W = P x t

Power = 900 W

Time = 30 s

W = 900 x 30

W = 27000 Ws

So work done is 2.7 x 10³ Joules
