Question

question #9 the total momentum of a system stays constant. question #10 which law states that momentum must be conserved. o newtons 1st law o newtons 2nd law o law of conservation of momentum o newtons 3rd law o newtons law of gravity o newtons 1st law o newtons 2nd law o the law of conservation of momentum

Explanation:

The law of conservation of momentum states that the total momentum of a closed - system remains constant. It is not Newton's 1st, 2nd, or 3rd law. Newton's first law is about inertia, the second law is $F = ma$, and the third law is about action - reaction pairs.

Answer:

Question #9: Law of conservation of momentum
Question #10: Law of conservation of momentum
