The power of a machine is 60 W. How much work can the machine do in 5 minutes?
Step 1
Given Data:
Power of a Machine
Power(P)=60W
Time(t)=5mins=5x60s=300s
Step 2
To find out: Work done by the machine
We know that
Power(P)=workdonetimeworkdone=powerxtimeW=Pxt=60x300=18000J
Hence, Work done by the machine is 18000 J
A machine does a work of 25kJ in 3minutes and 20seconds. Calculate the power of the machine in kW.
Power of a machine is its rate of doing work.
An engine can pump 30000L of water to a vertical height of 45 m in 10 minutes. Calculate the work done by the machine and its power.
A machine can help us in doing ……..work.
