I need help with this question...

Which of the following are correct representations of The Momentum Principle? (assuming a small-enough At whenever it shows up) P =F||+F Pf, z = Pi, z + Fnet, z t For every action there is an equal and opposite reaction. dP/dt=Fnet Pf, y = Pi, y + Fnet, y t The momentum of a system is conserved. Pf, x = Pi, x + Fnet, x t F = ma IS Pf =P, +Fnet t n = r i + vavg t For every gravitational and electrostatic force that one object exerts on another, there is an equal and opposite reaction force from the second object on the first. The rate of change of momentum of a system is proportional to the net external force on the system. P =Fnet t

Explanation / Answer

1,2,4,5,6,7,9,12 are the valid principles of momentum, please see that no 12 is also correct

if you have any doubt regarding explanations,you can ask me
