Is the force of the earth’s gravity on the sun stronger, weaker, or the same as the force of the sun’s gravity on the earth? explain why the sun’s attraction affects the motion of the earth more than the earth’s attraction affects the sun’s motion. employ newton’s second and third laws in your answer.

answer:

the first statement is false, the sun has a stronger gravitational pull.

explanation:

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.
