Question

A machine does a work of 2700 j in 30 second. What is the power of the machine?​

Answer 1

Step-by-step explanation:

we know that the power is equal to work done / time taken so,

2700/30 = 90 watts

Answer 2

Given -

• Work = 2700 J

• Time = 30 s

To find -

• Power of the machine.

Solution -

Formula to calculate power -

• $\sf{\dfrac{Work~done}{Time}}$

Substitute the given values.

⇛ $\sf{\dfrac{2700}{30}}$

⇛ 90 watts

$\large{\underline{\boxed{\sf{\red{Power= 90~watts}}}}}$
