A computer has a 800 W power supply.Calculate how much energy is transferred while it was used for 40 minutes.3 J20 J1.92 MJ3200 JI DON'T KNOWSUBMIT ANSWER
Solution
To calculate the energy transferred, we need to use the formula for energy which is:
Energy (Joules) = Power (Watts) x Time (Seconds)
First, we need to convert the time from minutes to seconds because the standard unit of time in this context is seconds.
1 minute = 60 seconds So, 40 minutes = 40 x 60 = 2400 seconds
Then we substitute the given values into the formula:
Energy = 800 W x 2400 s = 1,920,000 Joules
Therefore, the energy transferred is 1.92 MJ (since 1 MJ = 1,000,000 Joules).
