The average<span> speed of an object is defined as the distance traveled divided by the time elapsed. </span>Velocity<span> is a vector quantity, and </span>average velocity<span> can be defined as the displacement divided by the time. Hope this answers the question. Have a nice day.</span>
Answer:

Explanation:
The Law of Conservation of Mass states that mass cannot be created or destroyed.
So, in a chemical reaction, the mass before a reaction and after cannot be different. In other words, the mass of the products must be equal to the product of the reactants.
So, this is a <u>true statement.</u>

Answer:
Net force equals 0
Explanation:
Newton's first law states that an object at rest tends to remain at rest, and an object in motion tends to remain in motion with a constant velocity (constant speed and direction of motion), unless it is acted on by a nonzero net force. Note that the net force is the sum of all the forces acting on an object.
