∙ 10y agoUse the definition of power as energy / time. Or work / time; it's basically the same thing.

∙ 10y agoThe answer will depend on the power. The work can be done in one second or a billion years!
Power input = 700 WEfficiency = 75% so power output = 75% of 700 = 525 W Time = 30 seconds => Work done = 525W * 30s = 15750 W.s = 15750 Joules = 15.75 kiloJoules.
i done know
2 to the 2nd power is 4.
20GB as a power of 10 is 1010.30103
Power is calculated as the amount of work done divided by the time taken to do that work. In this case, the power used would be 600 Joules of work done in 10 seconds, which equals 60 Watts.
Work is the same as energy, equal to power times time. 500 watts for 2 minutes could be expressed as 1000 watt-minutes, but is more conventionally expressed as 500x120 watt-seconds, otherwise known as 60,000 Joules or 60 kJ.
I Did this when I was little too, all you do is w= f(d)The answer is 600J
Power
Power is a measure of how much work can be done in a certain amount of time. It quantifies the rate at which work is done or energy is transferred. Power is typically measured in units such as watts (W) or horsepower (hp).
The measure of how much work can be done in a certain amount of time is called power. Power is the rate at which work is done or energy is transferred. It is commonly expressed in watts (W) or horsepower (hp).

Power is the rate at which work is done, given by the formula Power = Work/Time. In this case, Power = 120 Joules / 60 seconds = 2 Watts.
Power is calculated by dividing the work done in Joules by the time taken in seconds. So, if x Joules of work are done in 10 seconds, the power used would be x/10 watts.
60 W
Power is the rate at which work is done. To find the power required to do 100 J of work in 5 s, divide the work by the time: 100 J / 5 s = 20 watts. If the same work is done in 1 s, the power required would be 100 watts, as power is inversely proportional to time.
