When driving straight down the highway at a constant velocity you have to give the engine a little gas (which means an added external force of tires pushing on the road) to maintain your uniform motion. Explain why this does not violate Newton’s 1st law. What are the other forces acting on the vehicle?"

Explanation:

This does not violate Newton's 1st law because the net force would still be 0 in order to produce uniform motion (aka constant velocity). The other forces acting on the vehicles is air resistance which is non-zero. So we need car internal force to counter balance this force, which require extra gas for the car.

are there answer choices to this question? this seems like a question where you have options to choose from.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
