When a 2-kg block is suspended from a spring, the spring is stretched a distance of 20 mm. determine the natural frequency and the period of vibration for a 0.5-kg block attached to the same spring

7.05 Hz

Explanation:

The natural frequency of a mass-spring system is:

To determine the constant k of the spring we use Hooke's law:

Δl  = F / k

k = F / Δl

In the first case the force was the weight of the 20 kg mass and the Δl was 20 mm.

F = m * a

F = 2 * 9.81 = 19.6 N

Then:

k = 19.6 / 0.02 = 980 N/m

Therefore:

the clapeyron equation (also called the clausius-clapeyron equation) relates the slope of a reaction line on a phase diagram to fundamental thermodynamic properties.
