Limiting reactants is the reactant that will be consumed first in a chemical reaction. in automobile, the primary reaction would be combustion reaction. the reactants would be oxygen and a fuel, since oxygen is readily available in the air, oxygen is not the limiting reactant. that is why fuel is always what we are monitoring in our automobiles, because it will dictates if the reaction can still occur or not.
This drag force is always opposite to the object's motion, and unlike friction between solid surfaces, the drag force increases as the object moves faster.
i just took the test on edg enuity it was B.The mass of the rocket decreases as fuel is burned, so the acceleration increases.
