Question

If you increase your work and decrease your time, you will haveA. more power.less power.the same amount of power.power rating can not be determined

Answer 1

You will have the same amount of power.

One way to look at this is:
If you work for 10hours at a normal rate (which we’ll call one) then 10x1 is 10. Your power is still at 10

If you work for 5 hours, but twice as hard, then you do 5x2 which is ten. The amount of power is always the same
