How much power is needed to do 1200 Joules of work in 90 seconds?
Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
What does one thousand watts equal?
That is called a kilowatt (kW). It is also equal to 1000 joules/second.
What is Planck's constant dimensionally equal to?
Planck's Constant is dimensionally equal to Angular Momentum. The unit is Joules second.
What is the rate at which work is done?
Work is energy, measured in joules. The rate of work, or joules per second, is known as watts, or power.
How are watts and joules related?
This is a very good question. A joule is a unit of energy, and a watt is a unit of power. Power is the rate at which energy is converted from potenital to kinetic energy. So power is some quantity of energy divided by some unit of time. In the SI system, a watt is equal to 1 joule per second. Real life example. A 60W lightbulb uses 60 joules of energy every second. Hope this helps!
What unit is power measured in?
The SI unit for power is the watt, which is equal to joules/second.The SI unit for power is the watt, which is equal to joules/second.The SI unit for power is the watt, which is equal to joules/second.The SI unit for power is the watt, which is equal to joules/second.
What is the unit measure for power?
The watt, which is equal to joules/second.

How much power is needed to do 1200 Joules of work in 90 seconds?
Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
What does power times time equal?
Power is defined as energy per unit time or Joules per second if you use SI units. This means that multiplying power by time leaves Joules, or energy. Power times time = energy
How many joules is equal to 7.456?
31.22 joules.
How many joules is 1 kWh equal to?
1 kWh is equal to 3.6 million joules.
What equals 100 watts?
That depends what you want to convert it to. Watt is a unit of power. 100 watts is equal to:0.1 kilowatts100 joules/second
What is the SL unit of power?
I don't know about SL. If you mean SI, the unit of power is the watt (equal to joules/second).
How many watts are 4680000000joules?
Watts are a measure of power, Joules are a measure of energy. The energy is equal to the power times the time. So if you have a power of 5 watts running for 7 seconds, that is 5x7 Joules of energy, or 35 Joules. Looked at another way, power measures how fast energy is converted. So 35 Joules converted in 7 seconds would be 5 watts of power, but it would need 35 watts to convert that energy in 1 second.
What does 80 joules equal to foot pounds energy?
80 joules is approximately equal to 59 foot-pounds of energy.
How long does it take to do 432 joules of work with 75 watts of power?
To calculate the time taken to do 432 joules of work with a power of 75 watts, you would use the formula: time = work / power. Plugging in the values gives you time = 432 Joules / 75 watts = 5.76 seconds.
