Which two factors does the power of a machine depend on?
lianna [129]

The power of a machine depend on two factors are work and time.

Option C

<u>Explanation:</u>

In science, power defined as the amount of work done in a unit time. i.e. delivering work in a rate of time or energy supply, expressed in input of work or transmitted energy divided by the time interval (t) or W/t.

Example: Some work can be done in the long run with a low-power engine or in a short time with a motor with high performance. The equation for power can be given as

              Power\ (in\ watts) =\frac{\text { work (joules) }}{\text { time (seconds) }}

              P=\frac{W}{t}
