Answer 2

Answer:

Given :-

• A man does 1200 J of work for 1 min.

To Find :-

• What is the power.

Formula Used :-

$\clubsuit$ Power Formula :

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

Solution :-

First, we have to convert time minutes into seconds :

$\implies \sf Time =\: 1\: minutes$

$\implies \sf Time =\: 60\: seconds\: \: \bigg\lgroup \small\sf\bold{\pink{1\: minutes =\: 60\: seconds}}\bigg\rgroup$

$\implies \sf\bold{\purple{Time =\: 60\: seconds}}$

Now, we have to find the power :

Given :

• Work Done = 1200 J
• Time = 60 seconds

According to the question by using the formula we get,

$\longrightarrow \sf Power =\: \dfrac{120\cancel{0}}{6\cancel{0}}$

$\longrightarrow \sf Power =\: \dfrac{\cancel{120}}{\cancel{6}}$

$\longrightarrow \sf Power =\: \dfrac{20}{1}$

$\longrightarrow \sf\bold{\red{Power =\: 20\: Watt}}$

${\small{\bold{\underline{\therefore\: The\: power\: is\: 20\: Watt\: .}}}}$
