Jules into kilojules?
kilo means 1000. 1 kilojoule = 1000 joules
An electric jug full of water needs 480000 joules to bring it to boil The element power is 1 Kilowatt how long will the jug take to boil?
1 kilowatt = 1000 joules per second, so it will take 480 seconds. (8 minutes).
If you apply a force of 10 N to a box and push it 10 m in 10 s how much power did you deliver?
as power=P=W/t=Fd/t=(10)(10)/10=10Watt
How much energy must be added to a 2-kg of glass with a specific heat of 644 J kg to increase its temperature from 10oC to 50oC?
51,520 Joules must be added to increase it's temperature to 100 C.
How many Therms per kWh?
A therm is an energy unit (equal to 100000 BTU) while kilowatts are power (energy/time). 1 watt = 1 Joule/second, and 1 kilowatt = 1000 Joules/second. The kilowatt hour is an energy unit (power X time = energy). 1 therm = 29.31 kWh
If it takes 5 seconds for you to do 1000j of work's what is your power output?
Power is defined as the rate at which work is done, and it is calculated by dividing the amount of work done by the time it takes to do that work. In this case, if you do 1000 joules of work in 5 seconds, your power output would be 200 watts (1000 joules / 5 seconds = 200 watts). This means you are exerting a power of 200 watts to perform the work.
How do you convert kilojoules to joules?
To convert from kilojoules to joules you have divide by 1000. meaning 1 kilo joule is equal to 1000 joules.
How do you convert from killi joules to joules?
To convert from kilo joules to joules you have divide by 1000 as 1 kilo joule is equal to 1000 joules. E.g. 2 kilo joules equals 2000 joules.
How much heat is in 1000 watts?
1000 watts is a measure of power, not heat. Power is the rate at which energy is used or transferred. To determine the amount of heat generated by 1000 watts, additional information about the time over which the power is used or the efficiency of the system is needed.
What is the correct conversion between joules and kilojules?
To convert joules to kilojoules, divide the number of joules by 1000. For example, 1 kilojoule = 1000 joules, 5000 joules = 5 kilojoules.
How many kilowatts are needed raise 480 tons of water by 10 degrees centigrade?
First, a kilowatt is a power unit equal to 1000 Joules per second. Raising water temperature, without specifying a timeframe is a question of how much energy is needed. You need to specify how fast you want to raise the temperature to get power kW. A tonne is 1000 kilograms, which is 10^6 grams, so 480 tonnes is 4.8 x 10^8 grams. It takes 1 calorie to raise a gram of water by 1°C, so it takes 10 x (4.8 x 10^8) calories = 4.8 x 10^9 calories. Taking 1 calorie = 4.1868 joules, we have 2.009664 x 10^10 joules, or 20.09664 gigajoules.
How many joules are in 980 kilojoules?
1 Kilojoule is equal to 1000 joules. So, 980 kilojoules x 1000 joules per kilojoule = 980000 joules.
When 1000 joules of coal is burned it only produces 500 joules of electricity What happened to the other 500 joules of energy?
Heat losses from the boiler flue, turbines, etc. Losses in the alternators - it takes an appreciable power simply to rotate them at generating speed without any load. 50% efficiency is probably quite good!
How many joules are in a kilojoule?
The answer is 0.001 kilojoules in a joule 1J = 0.001kJ
How much work is needed for a 30 meter by 5 meter ramp with 200 newtons of force needed to push a 1000 newton piano?
5000 joules
What is the heat equivalent to 4200 joules?
4200 joules is equivalent to 1000 calories, or 1 kilocalorie (kcal).
How many joules are in a kilojule?
There are 1000 joules in one kilojoule. This is because "kilo" stands for 1000 in the International System of Units (SI).
