A toy car rolls at a constant speed down a straight inclined track. When the car reaches the flat surface at the base of the inclined track, the speed of the car decreases.

Which statement best explains why the speed of the car decreases when it reaches the flat

surface

A. The force of gravity acting on the car increases

B. The force of gravity on the car decreases

C. The forces influencing the car are not balanced.

OD. The forces influencing the car are balanced.

DALL

the dependant variable is spilled water

the independent is the heat

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
