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.
Power = energy/timeWatts = joules/seconds(79.3 joules/37.2 minutes) x (minute/60 seconds) = 0.03553 watt= 35.53 mW = +15.5 dBm (rounded)====================To answer the question:(79.3 joules/37.2 minutes) x (minute/60 seconds) x (horsepower/745.7 watts) = 0.0000476 HP (rounded)47.6 microhorsepower(power output of 47.6 microhorses)
Work Done = Force x distance moved in direction of force WD = 900N x 100m WD = 90000 J Time = WD/Power Time = 90,000J/88W Time = 1022.727 s (3dp) Time = 17.05 Minutes (2dp) Sorted.
Great question! It depends on the size. 20 minutes = 0.66 hours. Small: 800 watts/hour 264 watts in 20 minutes Medium: 1440 watts/hour 475 watts in 20 minutes Large: 2000 watts/hour 666 watts in 20 minutes To get an idea of how much this is, in terms of cost and in comparison with other appliances, you may want to check out the related link.
The DC output of the XBox power supply is 135 watts.
27,000 J
300 watts
Multiply the watts by the seconds: 500 x 300 = 150,000 Joules is the answer.
The work or energy in Joules is the power in watts times the number of second it runs for. So 500 watts for 150 seconds is 75,000 Joules.
