An automobile with an internal combustion engine converts the potential energy of gasoline (44 mj/kg) into the kinetic energy of the moving pistons. if the average internal combustion engine is 10 percent efficient and 1 kg of gasoline is combusted, how much potential energy is converted into energy to run the pistons?

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 =

Since 10% is efficient of internal combustion.

Therefore, 4.4 MJ potential energy is converted  into energy to run the pistons.

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff

explanation:

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
