Physics Questions

We know that Kinetic energy is the energy of a moving object and in the same way Electrical energy is the form of kinetic energy caused by moving electric charges called electrons.

On the basis of magnetic properties, substances are classified into three groups namely diamagnetic, paramagnetic and ferromagnetic.

As solids diffuse and reorder very slowly under ambient conditions, the net, directionally dependent (anisotropic) magnetic moment can persist. Conversely, liquids and gases freely tumble and reorder: water rearranges every few pico seconds (10^12 times per second).

Hence liquids and gases can never show ferromagnetic properties.

A rotameter is a flow meter that measures volumetric flow of liquids and gases.

In S.I. System unit of angular momentum is "joule.Second".

SI unit of Planck's constant is joule-seconds(j-s).
