Answer:
C) 86 J of energy for every 100 J that enter it.
Explanation:
Efficiency is a measure of performance of an engine which can be calculated by the formula as given below to get in percentage:
Efficiency = energy output/energy input x 100
If the efficiency of a car’s engine is 14 percent it means that for every 100 joules of energy that is entered into it, only 14 joule is converted into useful output and rest of the 86 Joules is wasted.
The efficiency of any machine is never 100%, however, if any machine miraculously converts all the input energy to useful output energy, it means it is 100% efficient.
