An object on a vertical spring oscillates up and down in simple harmonic motion with an angular frequency of 14.2 rad/s. calculate the distance d by which the spring stretches from its unstrained length when the object is allowed to hang stationary from it.

0.04865 m

Explanation:

k = Spring Constant

m = Mass

d = Distance

g = Acceleration due to gravity = 9.81 m/s²

Angular frequency is given by

At equilibrium we have

The distance by which the spring stretches from its unstrained length is 0.04865 m

pe = weightxheight = 2000x1000=2,000,000joules

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.
