If you attach a 100 g mass to the spring whose data are shown in the graph, what will be the period of its oscillations?
ycow [4]

if for a force of 0.5 N we have a displacement of -0.02m we can calculate the elastic constant(k) with the formula F=-kx(F=0.5N x=-0.02)

k=F/x k=0.5/0.02=25N/m

now we can calculate the period by the formula

T=2π√(m/k)

in the mass we convert grams to kilograms so 100g=0.1kg

T=6.28√(0.1/25)⇒T=0.39seconds

Describe the relationship between temperature and energy
yKpoI14uk [10]

Answer:

The Temperature is the measure of Average Kinetic Energy  of the molecule in the substance.

Temperature and Kinetic Energy of molecules are related by the equation

= \frac{3}{2} kT

Where

<E> denotes average kinetic energy

k - Boltzmann constant

T - Temperature of the substance

Explanation:

The energy inside the substance is characterised by translational and vibrational motion.

The molecules in a substance have a range of kinetic energies because they don't all move at the same speed. As a substance absorbs heat the particles move faster so the average kinetic energy and therefore the temperature increases.

As the molecules of a substance vibrate faster their temperature increases.

Thus an increase energy corresponds to an increase in temperature

<E> α T (α denotes proportionality)

= \frac{3}{2} kT
