No, because that would mean the car essentially uses zero fuel. Even a go cart or bicycle requires the consumption of some fuel (e.g. calories from leg power).
No, no machine is 100% efficient.
it is not very efficientAnswerThey are 100 percent efficient.
No. Nothing is 100 percent efficient. In any situation some energy will be given off in a form that is useless to us.
Basically, almost NO physical process is 100% efficient.
because they are not proper
at 0'kelvin
Sweating is no longer efficient near 100 percent humidity.
Some energy is lost to friction.
No; it is not possible.
Play a play a game
becaus ethey have friction
They can never reach that level of efficiency.
