Question

A person perform 420 j of work in 5 minutes calculate power delivered by him​

Answer 1

$\mathfrak{\large{\underline{\underline{Answer:-}}}}$

$\boxed{\sf</strong><strong>\</strong><strong>r</strong><strong>e</strong><strong>d</strong><strong>{ </strong><strong>P</strong><strong> </strong><strong>=</strong><strong> </strong><strong>1</strong><strong>.</strong><strong>4</strong><strong> </strong><strong>w</strong><strong>}}$

Explanation:

Work done = 420 j

Time taken = 5 minutes

Power is calculated by the formula :-

★ $\boxed{\sf{ P = \frac{work \: done}{time \: taken} }}$

put the value.

$\implies$ $p \: = \frac{420}{300}$

$\implies$ $p = 1.4w$

hence, the power delivered by man is 1.4 watt.
