:
(A) conserve mass
(B) conserve momentum
(C) conserve KE
(D) none of these
lid resting​

Answer 1

Answer:

When a bullet is fired from a gun. The gun recoils to conserve momentum.

Explanation:

Because there is no external force on the gun-bullet system, it would conserve momentum. If the bullet gain momentum in one direction, the gun would gain momentum in the opposite direction.

Answer 2

Answer:

Option B) conserve momentum is correct answer.

Explanation:

Additional information

• The recoiling of a gun is accounted for by the principle of conservtion of linear momentum .
• When a bullet is fired from a gun, the gun exerts a force on the bullet in the forward direction. ... The bullet also exerts an equal and opposite force on the gun in the backward direction. Therefore a gun recoils when a bullet is fired from it.
