$\clubsuit$ Power Formula :

$\mapsto \sf\boxed{\bold{\pink{Power =\: \dfrac{Work}{Time}}}}$

Solution :-

Given :

• Work = 40 J
• Time = 4 seconds

According to the question by using the formula we get,

$\longrightarrow \sf Power =\: \dfrac{\cancel{40}}{\cancel{4}}$

$\longrightarrow \sf Power =\: \dfrac{10}{1}$

$\longrightarrow \sf\bold{\red{Power =\: 10\: W}}$

${\small{\bold{\underline{\therefore\: The\: power\: of\: a\: body\: is\: 10\: W\: .}}}}$
