1 W is 1 joule per second so I reckon it's 300x60 = 18000 Joules.
60 W
as work done is dot product of force and displacement so cos(90)=0;therfore work done is zero
Work done is equal to Force multiplied by distance:Wd = FxdWd = 324x3Work done = 972 Joules.
Work is said to be done where certain displacement is involved. Ex. Of work not done is Coolie carrying Load on his head..
as power=P=W/t=Fd/t=(10)(10)/10=10Watt
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.
The work done can be calculated using the formula: work = power × time. Substituting the given values, the work done would be 478 Watts × 14 seconds = 6692 Joules.
The work done can be calculated using the formula: Work = Power x Time Substitute the given values: Work = 550 watts x 55 seconds Work = 30250 joules So, 30250 joules of work was done.
The power used would be 60 watts. This can be calculated by dividing the work done (600 joules) by the time taken (10 seconds).
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.
The work done can be calculated using the formula: Work = Power x Time. Plugging in the values, we get Work = 600 watts x 45 seconds = 27,000 joules. Therefore, 27,000 joules of work was done.
(600 Watts) x (4 minutes) = (600 joules per second) x (240 seconds) = 144,000 joules =144 kilojoules
The power used would be 60 watts. This can be calculated by dividing the work done (600 J) by the time taken (10 seconds), resulting in 60 watts.
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.
If a human adult uses energy athe rate of 100 watts, or 100 joules per second, and sustains this rate for 10 seconds, the work done equals 1 kilojoule.
The power required to do 50 joules of work in 5 seconds is 10 watts. This is calculated by dividing the work done (50 joules) by the time taken (5 seconds), which equals 10 watts.
Zero.
