Aspring is mounted horizontally, with its left end fixed. a spring balance attached to the free end and pulled toward the right indicates that the stretching force is proportional to the displacement, and a force of 6.0 n causes a displacement of 0.030 m. we replace the spring balance with a 0.50 kg glider, pull it 0.020 m to the right along a frictionless air track, and release it from rest. (a) find the force constant k of the spring. (b) find the angular frequency w, frequency f, and period t of the resulting oscillation.

200 N/m

20 rad/s

0.31415 seconds

3.18309 Hz

Explanation:

m = Mass of glider = 0.5 kg

x = Displacement of spring

F = Force on spring = 6 N

From Hooke's law we have relation

The spring constant is 200 N/m

Angular frequency is given by

The angular frequency is 20 rad/s

Frequency is given by

The frequency is 3.18309 Hz

Time period is given by

The time period is 0.31415 seconds

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.
