Question

What would happen when a two-dimensional array of ball bearings is shaken?

a. Changing frequency would do nothing, we need to change the temperature.

b. As the frequency of the driver increased the ball bearings went through the following phase changes. Solid - Liquid - Gas

c. As the frequency of the driver decreased the ball bearings went through the following phase changes. Gas - Liquid - Gas

d. As the frequency of the driver increased the ball bearings remained Solid, or, the ball bearings never moved.

e. As the frequency of the driver increased the ball bearings went through the following phase changes. Gas - Solid - Liquid

Explanation / Answer

As the frequency is increased, it makes more number of revolutions per second. As in each revolution some energy is dissipated in to heat it ma Melt from solid to liquid and further to gas also. Hence the correct choice of answer is option "b".
