Question

The expression of power ‘P’ is

(a) mgh (b) p=1/2 mv2

(c) P = F x d (d) P= F x d/t​

Answer 1

(d) P = (F×d)/t is the correct answer

Answer 2

Answer:

d)P=F×d/t

Explanation:

$because \\ power = \frac{work \: done}{time \: taken} \\ as \: we \: know \: \\ work \: done \: = force \times distance \\ thus \: f \times d \\ therefore \\ f \times \frac{d}{t} \\ = \frac{fd}{t} \\ hence \: proved$
