That depends on the exact circumstances. For example, in electrical circuits, power = I2R. However, since the current, in turn, depends on the voltage and the resistance, it is better to express this as V2/R. For mechanical energy, power is basically speed times force.
the power it is givin.
no
they both depend on weather
nope!
That would depend on the power supply.
Army/Troops
Horse power and gear ratio.
they depend on the tide and arent very realible
If you know the power you do not need to calculate it by anything. And if you don't, the answer will depend on what measure you do know!
Ontarians depend on forests for fire wood, pencils, paper and houses. They depend on rivers for fish to eat. They use hydroelectic power from fast flowing rivers.
hi
flowing water to turn turbines
