Answer:
4.4 MJ
Explanation:
We are given that an automobile with an internal combustion engine converts the potential energy of gasoline into kinetic energy of the moving piston.
1 kg of gasoline gives energy=44 MJ.
Average internal combustion engine =10 % efficient
We have to find how much potential energy is converted into energy to run the pistons.
10% of 44 =[tex]\frac{10}{100}\times 44=4.4 MJ[/tex]
Since 10% is efficient of internal combustion.
Therefore, 4.4 MJ potential energy is converted into energy to run the pistons.
