Question
An air conditioner is turned on and used for 10 800 seconds.During that time, it transfers 40.5 MJ of energy.Calculate the power of this air conditioner.Give your answer in watts. Make sure to include the units in your answer.
Solution
To calculate the power of the air conditioner, we need to use the formula for power which is:
Power = Energy / Time
The energy is given in Mega Joules (MJ) and the time is given in seconds. However, we need to convert the energy from MJ to Joules (J) because the standard unit of energy in the International System of Units (SI) is the Joule.
1 MJ = 1,000,000 J
So, 40.5 MJ = 40.5 * 1,000,000 J = 40,500,000 J
Now we can substitute the values into the formula:
Power = 40,500,000 J / 10,800 s = 3750 W
So, the power of the air conditioner is 3750 Watts.
