Clyde and marilyn are riding a roller coaster. during which section of the track is their potential energy converted to kinetic energy?

Potential energy is when the roller coaster rises. Kinetic energy is when the roller coaster declines.

i think the answer would be reserve.

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
