What wavelength would equal 5 joules?
You can't determine the amount of wavelength that equals 5 joules. Wavelength measures the length of the period while joules measure energy.
How does solar energy reduce the use of fossil fuels?
Most countries burn fossil fuels to generate electricity.If they used solar power to generate electricity, thenThey would not have to use so much fossil fuel.Solar Energy itself does not reduce the use of fossil fuels. But the use of solar energy should hopefully reduce the need of fossil fuels to create energy, so therefore the more we can use solar power as an energy source instead of fossil fuels, the more we reduce the use of fossil fuels.
Is it reasonable to have a work output of 150 Joules when work input is 110 Joules?
No. It is not reasonable. If that ever happened, we would have to ask where the additional 40 joules came from, since energy cannot be created or destroyed. If there were something inside the box that added 40 joules to the 110 passing through, then that 40 would need to be added to the "input" work.
Why 2 objects at the same temperature will have different amounts of energy if one has a larger mass?
All objects have a specific heat capacity, the amount of energy it takes to increase the temperature of one gram of the object by one degree centigrade. Therefore, if an object has a specific heat capacity of say, 500 joules, and you wanted to heat 3 grams of that object by 1 degree, you would need 1500 joules of energy. But if you put that 1500 joules of energy into only 1 gram of the object, you would heat it by 3 degrees.
A 60 watt light bulb runs for 5 seconds how much energy does it use?
That would be 40x60 watt-seconds, also known as Joules, so it's 2400 Joules of energy. 3.6 MegaJoules is equal to one kilowatt-hour, also known as 1 unit.
What is the unit of energy of inductor?
I am not entirely sure what you mean. Energy is measured in joules. The energy stored in an inductor would therefore also be measured in joules. The "strength" of an inductor is measured in henry, but that is not an energy unit.
What wavelength would equal 5 joules?
You can't determine the amount of wavelength that equals 5 joules. Wavelength measures the length of the period while joules measure energy.
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.
Where would solar energy be good alternative to using fossil fuels?
solar energy would be a good alternitive energy
What measurement is energy measured in?
It depends, If you measure your own energy it would be in joules, if it is for your house you measure it with kilo-watt hour
What energy comes from things besides fossil fuels?
What energy comes from things besides fossil fuels
Converting kilograms to Joules?
Kilograms are mass units, Joules are energy units. You could use Einstein's energy-mass equivalence and multiply the mass (in kg) by the speed of light (in m/s) squared; that would give you the energy equivalent in Joules of a given mass.
How long would a 60 watt light bulb have to burn to produce the energy you used climbing the stairs?
If you weigh 70 kg and the stairs are 3 metres high, the energy needed is 70 x 9.8 x 3 Joules or 2058 joules. That would keep a 60 w bulb going for 2058/60 seconds, or 34.3 seconds. But to produce that same energy in a generating plant, the fuel energy wasted in the process would be between 2000 joules for a gas plant of 50% efficiency, and 6000 joules for a coal plant of 25% efficiency.
What is an amount of water whose temperature would change by 15 degrees Celsius when it absorbs 2646 joules of heat energy?
The amount of water whose temperature would change by 15 degrees Celsius when it absorbs 2646 joules of heat energy is 42,2g H2O.
If coal energy where to run out what would you use in its place?
fossil fuels
