Question

A machine does 30j work in 6 second find its power

Answer 1

Answer:

5 Watt

STEP BY STEP EXPLANATION:-

Power=Energy(in joule) ÷ Time

P=30÷6

So, Power=5 Watt

Answer 2

Answer:

Given :-

• A machine does 30 joules in 6 seconds.

To Find :-

• What is the power of the machine.

Formula Used :-

$\clubsuit$ Power Formula :

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

Solution :-

Given :

$\bigstar\: \: \rm{\bold{Work =\: 30\: J}}$

$\bigstar\: \: \rm{\bold{Time =\: 6\: seconds}}$

According to the question by using the formula we get,

$\longrightarrow \sf Power =\: \dfrac{\cancel{30}}{\cancel{6}}$

$\longrightarrow \sf Power =\: \dfrac{\cancel{15}}{\cancel{3}}$

$\longrightarrow \sf Power =\: \dfrac{5}{1}$

$\longrightarrow \sf\bold{\red{Power =\: 5\: Watts}}$

$\therefore$ The power of the machine is 5 Watts.
