If forces acting on an object are unbalanced, which factors may result from an unbalanced force? Select three options. a. The net force is negative. b. The net force is zero. c. The net force is positive. d. There is a change in motion. e. There is no change in motion.

a, c and d

Explanation:

Force is the product of mass of a body and its acceleration. Unbalanced force is a force that produces a net force for example a 5 N force acting in the positive x axis direction is opposed by 10 N for in the negative x axis

the net force or unbalance force = 5 - 10 = - 5N  which means the body will move in the negative axis direction. Factors which may result in unbalanced force are a) the net force is negative c) the net force is positive d) there is a change in motion of the body

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.
