Can someone help me identify two food chains in the ecosystem of Southeast Asia rainforest this is for a project would honestly help lots (only answer if you are serious)

the bal will not change its velocity.

it would be c. predictability

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.
