Answer: Work done = 2o joules

               Time = 10 sec.

               Power = W/T

                          =   20/10

                           = 2 watt

The power of the machine = 2 Watt

Given :

A machine performs 20 J of works in 10 sec

To find :

The power of the machine

Formula Used :

\displaystyle \sf Power  =  \frac{Work \:  done}{Time}

Solution :

Step 1 of 2 :

Write down work done and time

The machine performs 20 J of works in 10 sec

Work done = 20 J

Time = 10 sec

Step 2 of 2 :

Calculate power of the machine

The power of the machine

\displaystyle \sf   =  \frac{Work \:  done}{Time}

\displaystyle \sf   =   \frac{20}{10}  \:  \:J/s

\displaystyle \sf   =   2  \:  \: Watt
