What type of energy is due to motion potential energy or kinetic energy

Kinetic Energy

Explanation:

Potential Energy is where something is building up energy to move.

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.

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
