When two objects collide, the momentum of the system remains constant. this is a statement of a. change in momentum b. newton’s third law c. impulse d. the conservation of momentum

B. Newton's third law

Explanation:

When two bodies collide the moment remains constant.

This occurs because we define a system that is formed by the two bodies, so that the forces last = before the shock are forces of action and reaction, from one body to the other, so that for the system (two bodies) the force total is zero, we assume that the system is isolated from the outside.

In summary, the initial establishment is a consequence of Newton's third law

good for her? ? where is the question?

electromagnetic waves travel through space with vacuums. give me brainliest if right.
