Strictly speaking, it's not. It's connected to the fact that the mechanical energy can be converted to IR radiation (or other kinds of EM waves), or it can be converted to the vibrations of the material's lattice and so on.
No. In heat energy, there is always a certain amount of unusable energy. What amount depends on the availability of colder objects.
Yes. But it is a negligible amount comparing to the mechanical energy it produces.
A generator doesn't really have any significant amount of energy; it is supposed to convert mechanical energy into electrical energy - but it doesn't store it.
For example, if a heated gas expands, it can make things move.Please note that you can't convert ALL heat energy into mechanical energy or other types of useful energy; the maximum theoretical amount of heat you can convert is limited by the Carnot formula.
Totally
No, the mechanical advantage is greater than 1. If you input a force of 1 unit you get out a force of 1+ units. However keep in mind that if this were a PERFECT machine the amount of WORK INPUT is EQUAL to the the amount of WORK OUTPUT. Since perfection is not possible, and there are frictional losses this is not possible. Otherwise you could have a perpetual motion machine, which is not yet possible.
mechanical advantage
yes. piezoelectric crystals can convert mechanical energy (applying physical force) to electrical energy, and vice versa. however, this is a very tiny amount of electricity.
the amount of enerygy transferred by a force
No. They both have totally different pin sizes and amount of pins. Socket AM2 has a lot more pins, socket a has 462 pins.
mechanical advantage _ l l -
Yes, but irrigation would be required and that means lots of water. A person would have to double the amount of precipitation at least.
