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

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
