A proton moves in a circle in radius 20 cm perpendicular to a field of magnitude 0.005 T. Find the magnitude of its momentum. (qp= 1.6 × 10-19 c)

answer; (arch); good luck

i would say the answer is food.

hope this !

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.
