A heavy box sits on a floor. The net force on the box can be represented as which of the following? A -zero vector pointing up
B. Non-zero vector pointing down
C. Non- zero vector pointing left
D. Non- zero vector pointing right
E. It is zero

yup its correct its: c) b b

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.
