Final answer:
The scenario of a bullet embedding into a block and transferring its momentum exemplifies the Law of Conservation of Momentum since the total momentum of the system remains constant in the absence of external forces.
Step-by-step explanation:
The scenario described involves a bullet transferring all of its momentum to a block it embeds in, which indicates the concept of the Conservation of Momentum. This principle is fundamental in physics, stating that the total momentum of a closed system remains constant when no external forces act on it. In this case, if the bullet and block system is isolated, the momentum before the collision (bullet traveling towards the block) is equal to the momentum after the collision (the combined mass of the bullet and block moving together).
Answering the multiple-choice question, the bullet embedding into the block and transferring its momentum without external forces acting on the system is an example of: A. Law of Conservation of Momentum.
