Suppose a soccer ball is kicked from the ground at an angle 20.0º above the horizontal at 8.00 m/s. The initial y-velocity is determined to be 2.74 m/s. If the ball lands at the same height at which it was kicked, what is the value of Δy for the ball?

answer; equivalent to a one(1) horsepower motor;

the rearrangement of particles in a physical change. hope this

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.
