If you run with an average speed of 3.9 meters per second for 1,200 seconds, then what distance will you have traveled?

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.

force tends to be low and long diustance masses are high
