What is the capital of Egypt? ( Cairo )

1 Answer

  1. The correct answer is: d Some potential energy changes into kinetic energy.

    Explanation: When two magnets are in a system where they either attract or repel each other, the potential energy of the system decreases as they move closer together (in the case of attraction) or further apart (in the case of repulsion). As they move, this potential energy is converted into kinetic energy, causing the magnets to accelerate. Therefore, some of the potential energy is transformed into kinetic energy as the magnets move.
