Power = 400 WTime = 2.5 minutesCalculate the work done.Work done = _____ kJ

To calculate the work done, we first need to convert the time from minutes to seconds because the standard unit of time in physics is seconds.

1 minute = 60 seconds So, 2.5 minutes = 2.5 * 60 = 150 seconds

We know that Power = Work done / Time. So, rearranging for Work done gives us:

Work done = Power * Time = 400 W * 150 s = 60000 Joules

Since 1 kJ = 1000 J, we convert Joules to kiloJoules:

Work done = 60000 J / 1000 = 60 kJ

So, the work done is 60 kJ.
