Answer: Because The potential energy you build going up the hill can be released as kinetic energy — the energy of motion that takes you down the hill. Once you start cruising down that first hill, gravity takes over and all the built-up potential energy changes to kinetic energy. Gravity applies a constant downward force on the cars.Potential energy is the energy an object has as a result of its position. Potential energy is stored energy that has not yet been released. Gravitational potential energy is potential energy that results from an object's position in a gravitational field, and is equal to the object's weight multiplied by its height.
hope this helps have a nice day❤️

Answer:
The sex cells could not easily combine to form the body cells of an offspring because of the different chromosome number.
Explanation:
Answer: The correct answer is -
B) haploid.
Meiosis is a type of cell division that occurs during the process of formation of gametes particularly sexually reproducing organisms.
Gametes are reproductive, sex cells that are haploid (having half the number of chromosomes as their parent cell).
Thus, during meiosis a diploid parent cell gives 4 haploid daughter cells, called gametes (such as eggs and sperms).
