The efficiency of a car’s engine is 14 percent. this implies that the engine wastes a) 14 j of energy for every 86 j that enter it. b) 14 j of energy for every 100 j that enter it. c) 86 j of energy for every 100 j that enter it. d) 100 j of energy for every 114 j that enter it.

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.

Hope it helps!

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.
