Suppose an object with a weight of 272 pounds displaces a spring 45.3333 feet if it is placed on the spring vertically. Suppose this spring is laid horizontally and has one end attached to a wall and the other end attached to the object is laid on the floor and that the friction of the mass with the floor (i. e., the damping constant) is 2 lbs⋅s/ft. Determine the mass m and the spring constant k. If needed, use g=32ft/s2. m= slugs. k= lbs/ft.

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.

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
