Which ocean had the greatest average depth

The Pacific ocean has the greatest average depth of 4280 meters.

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

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.
