Un cuerpo es lanzado desde el piso verticalmente hacia arriba con una velocidad inicial V0= 30m/s. Determine: a. La altura máxima alcanzada. b. El tiempo de altura máxima. c. El Tiempo de altura máxima. d. El Tiempo en el aire. e. Velocidad en altura máxima

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.

a. spokes of a wheel.

as indicated in the question radial contains rad, also found in radius, so the fracture's would span the radius.
