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.
Calculate the power in watts used if you exert 50 joules of work in 5 seconds?
Watts is joules per second, so 50 joules in 5 seconds is 10 watts.
Why was James watt so important?
his work was so important because he improved the steam trains by making them run with out water and invented some parts of electric e.g 30 watts of electricity in a light bulb he named it after himself
Do 100 joules of work in 50 seconds and your power output is?
If one were to do one hundred Joules of work in five seconds, he/she would have a power output of 20 Watts.
How much work can a 500 watt electric mixer do in 2.50 minutes?
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.
Amps to watts?
Watts = Amps x Volts Amps = Watts / Volts you only need to know two of the three to work out the other so 230 volts at 10 amps gives 2300 Watts (2.3 kW) 2.3kW at 230 volts draws 10 Amps
What size generator do you need to run a 7.5 hp motor?
Conversion from gas to electric should be 750 watts/hp So 7.5*750=5625 watts These are running watts so that is a bare minimum. Depending on the application it needs much more starting watts (up to 3 times for a compressor). Generator should be no less than 8000 watts, maybe more if you work it hard.
1500 watts equals how many volts?
Watts is a power level, not a voltage. The wattage in a circuit is defined as Volts x Amps, so you need to know the current before you can work out the voltage.
How many watts is 20 rms watts?
Rms is watts that's the amount of watts a speaker is rated for.
Why was James watt work so important?
He wasn't...
How many horspower is in 1 kilowatt?
They are both measures of power, i.e. the rate of doing work. One HP is defined as 746 watts, so 1 kilowatt is 1.3405 HP.
How many kilowatts are there in 124 watts?
1 kilowatts = 1000 watts. so, 124 watts = 0.124 kilowatts.
