How long does it take to perform 450 Joules of work with 25 watts of power?
18 Seconds (:
How long does it take to perform 500 Joules of work with 25 watts of power?
Divide 500 by 25. The answer is 20.
How long does it take to perform 480 Joules of work with 20 watts of power?
480 joules = 480 watt-seconds20 watts x (time) = 480 watt-secondsDivide each side by 20 watts:Time = 24 seconds
How much power does it take to do 104j of work in 60 seconds?
Power (Watts) is Joules (energy) per Second (time) so divide the number of joules by the number of seconds. 104/60 = 1.733 Watts
How long does it take to do 432 joules of work with 75 watts of power?
A watt is equal to 1 Joule per second. So 432 Joules * (1 / 75 Joules per second) = 432/75 = 5.76 seconds.

What is the formula to work out horsepower?
Horsepower is a unit of power. 1 horsepower = 745.699872 watts The formula for Power is this: Power = Work/TimeThe SI unit of power is the watt (W), which is equal to one joule per second. The SI unit for work is the joule (J). The SI unit for time is seconds (s).
How long does it take for a 100-watt light bulb to consume 100 watts of energy?
it will take more than100 watts until the filament reaches operating temperature so perhaps a second to get as low as 100 watts . then 100Watts there after until 300 hours pass then 0 watts if you mean 100Watt hours then the answer is 1 hour and the hour will cost about a penny
How long will it take to produce 150kw from 780 joules of energy?
If you can stuff the 780 Joules of energy through the system in 0.0052 second,then the power during that time is780/0.0052 = 150,000 watts.But it only lasts for that 5.2 milliseconds, and then you're out of joules.
How many watts of energy does it take to lift 1000 pounds ten feet?
Energy is measured in Joules, not in Watts. Watts is a unit of power, and is equal to Joules / second. To calculate the potential energy (in Joules), convert the units to SI units (lbs to kilograms, feet to meters), then use the formula potential energy = mass x gravity x height. Use 9.8 meters per second square for gravity. A2: The Energy to lift 1000 # 10 feet is 10kft# or 40/3 k Joules.
How many watts of power does it take to run the average home in Canada?
15 watts
How much energy does a blow dryer take?
They come in different sizes, and power ratings. Look at your dryer; somewhere it should have electrical specifications. These should either include a power (in watts), or volts and amperes separately. If volts and amperes are listed separately, multiplying them gives you a good idea of the amount of watts consumed. Note: watt is a unit of power, not of energy. You need to multiply that by the time you use the device, to get energy: joules = watts x seconds
