"Escriba la fórmula matemática que permite calcular la fuerza y el peso de un cuerpo que cae desde cierta altura."

answer: i pick a

explanation:

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

f is prop to m1xm2 double m1 double force

reserve is the answer
