Some of the factors that decrease efficiency of automobiles include:
A) friction between tires and the road
B) Energy lost as heat during combustion inside the engine
C) their heavy weight relative to the weight of passengers
D) friction and energy lost as heat during combustion inside the engine
E) all of these answer choices are correct

Question

Quizplus · Accepted Answer

All of the answer choices listed contribute to a decrease in automobile efficiency. Friction between tires and the road creates resistance that the engine must overcome, energy lost as heat during combustion represents wasted energy that could have been used to power the vehicle, and heavy weight relative to the weight of passengers means that more energy is required to move the vehicle.
