Question
A printer is used for 4 minutes. During that time, it transferred 79 200 J of energy.Calculate the power of this printer.Give your answer in watts. Make sure to include the units in your answer.
Solution
To calculate the power of the printer, we need to use the formula for power which is:
Power = Energy / Time
The energy transferred is given as 79200 Joules and the time is given as 4 minutes. However, the standard unit of time in this context is seconds, so we need to convert the minutes to seconds.
1 minute = 60 seconds So, 4 minutes = 4 * 60 = 240 seconds
Now we can substitute the values into the formula:
Power = 79200 J / 240 s = 330 W
So, the power of the printer is 330 Watts.
