The amount of work done by the motor is equal to 6.72 Megajoules.
Given the following data:
- Power = 5.6 Kilowatt = 5600 Watts.
Conversion:
- 20 minutes = [tex]20 \times 60 = 1200[/tex] seconds.
To determine the amount of work done by the motor:
Mathematically, the work done by an object with respect to power and time is given by the formula:
[tex]Work\;done = power \times time[/tex]
Substituting the given parameters into the formula, we have;
[tex]Work\;done = 5600 \times 1200[/tex]
Work done = 6,720,000 Joules
Note: 1,000,000 Joules = 1 Megajoules.
Work done = 6.72 Megajoules.
