Question

The amount of power has decreased. This is most likely the result of less work being done over a longer period of time.

less work being done over a shorter period of time.
the same amount of work being done over a longer period of time.
the same amount of work being done over a shorter period of time.

Answer 1

The first option is the most correct.

Answer 2

Option (A)

Step-by-step explanation:

Power is defined as the rate of doing work.

Or

The work done in unit time is defined as the power.

The formula for the power is given by

`Power = (Work)/(Time)`

Power is a scalar quantity and its SI unit is Watt.

As the power is decreased, either work is decreased or time is increased.

So, if a less work is done in a longer period of time, the power is decreased.
