Answer 2

$\huge \mathfrak{solution}$

$\displaystyle \large{ \sf{given}}$

$\displaystyle \large{ \sf{work \: = 2700j \: }}$

time = 30s

Required -;

90W

To find

power of machine

Formula,,

we know that

$\displaystyle \large{ \sf{ \red{power = \frac{work}{time}}}}$

$\displaystyle \large{ \sf{ \frac{2700j}{30s} = 90w}}$

A machine does a work of 2700 J in 30 s. then power of machine is 90W
