Respuesta :

Power Rating = [tex]\(1.1 \times 10^3\)[/tex] W

Time for which the machine is operating = 2 hours

Time in seconds  = 2 × 60 × 60

Time = 7200 seconds

Now, we need to use the formula for work done.

Work done = Power × time

Work done = [tex]\( 1.1 \times 10^3 \times 7200\)[/tex]

Work done = [tex]\(7.92 \times 10^6\)[/tex] Joules

Hence, work done by the machine in 2 hours is [tex]\(7.92 \times 10^6\)[/tex] J.

The answer to this question is 7.92 * 10^6 J
