If a motor is rated at 5.6KW, work done in 20minutes is equal to:​

Answers

Answer 1

Answer:

given Power= 5.6×1000=5600watt

t=20min=20×60=1200sec. work done=?

P=w/t

w=pt=5600×1200=672×10^4Joule

Answer 2

The amount of work done by the motor is equal to 6.72 Megajoules.

Given the following data:

Time = 20 minutesPower = 5.6 Kilowatt = 5600 Watts.

Conversion:

1 minute = 60 seconds20 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.
