A dishwasher takes 1.5 hours to wash one load.During this time, it uses 11.34 MJ of energy.Calculate the power of this dishwasher.Give your answer in watts.

To calculate the power of the dishwasher, we need to use the formula for power which is:

Power = Energy / Time

The energy is given in MegaJoules (MJ) and the time is given in hours. However, we need to convert these units to Joules (J) and seconds (s) respectively, because the standard unit of power (watt) is derived from Joules and seconds.

1 MJ = 1,000,000 Joules 1 hour = 3600 seconds

So, the energy used by the dishwasher is 11.34 MJ = 11.34 * 1,000,000 = 11,340,000 Joules

And the time taken is 1.5 hours = 1.5 * 3600 = 5400 seconds

Now we can substitute these values into the formula:

Power = 11,340,000 J / 5400 s = 2100 Watts

So, the power of the dishwasher is 2100 Watts.
