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).
Basically, almost NO physical process is 100% efficient.
because they are not proper
at 0'kelvin
No; it is not possible.
No, nuclear generators are not 100 percent efficient. They typically have an efficiency rate of around 30-40%, which means that 30-40% of the energy from the nuclear reactions is converted into electricity, while the rest is lost as heat.
Some energy is lost to friction.
becaus ethey have friction
A common device that fits this description is a combustion engine, such as those found in cars. These engines convert the heat generated from burning fuel into mechanical energy to do work, but they are not 100% efficient and expel excess heat through the exhaust system.
To write 11 percent as a fraction, you divide the percent by 100 and simplify the fraction if possible. In this case, 11 percent is written as 11/100.
No because it will lose electron by core losses and winding losses
friction and entropy the production of heat with in a system
Just put it over 100. 168 percent = 168/100
