A ball of 5.2 kg is swings around on a rope with radius 0.86 meters. If the ball is traveling at 1.8 m/s, what is its angular
momentum? (Round to the nearest hundredth).

Explanation:

Angular momentum is L = mvr:

L = (5.2)(1.8)(.86) so

L = 8.05 kg*m/s

unlike poles attract

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.
