A force f acts in the x direction, its magnitude given by f=ax2, where x is in meters and a is exactly 9. 0 n/m2.

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.

true tan speed = ang vel x radius

d. air pressure decreases as altitude increases.
