1000km which is realy powerful but it can let you live until your 200 years old
50% energy
On average, humans give off about 100 watts of heat energy.
Because, it is booming hot.
Infrared light doesn't "give off" energy; in this case, it IS the energy.
you give off calary and diet energy
No. Neither High or Low pressure Sodium Vapour lamps give off much energy in the UV wavelengths.
Computers give off mostly heat, but also give off magnetism in the form of radio waves. Plus their displays give off light energy and the speakers give off sound waves. The fans inside create kinetic energy.
yes!
Electrical energy.
Yeah, I need to know for my school project!!! HELP!!!
It gives off thermal energy.
Electrical energy can be converted to light. In addition, nuclear energy as in a nuclear weapon will give off a blinding flash of light. Also, using fireflies as an example, chemical reactions can also give off light energy.
