atomic = no of protons.

mass number-atomic number = neutron number

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential

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.
