A student that just received their driver's license decides to buy a new car. He remembers from physics class that heat engines have a thermal efficiency that can
be calculated. He asks the car dealer for a car that has a high thermal efficiency
rating. The car dealer says he has a car that is 100% efficient.
Which law of thermodynamics best describes why the car cannot be 100% efficient?

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

hope that !                                         : )

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide

option number c is the right answer.
