What is density?
Density is a physical characteristic, and calculates of mass per unit of volume of a material or substance. It is a measurement of the quantity of matter in a given volume of something.
The higher an object's density, the higher it's mass per unit of volume. The average density of an object equivalent its total mass divided by its total volume. A denser object (like iron) will have less volume than an equal mass of some less dense substance (like water).
STABLE EQUILIBRIUM If object is in stable equilibrium and if we displace object to a very little displacement dr then it will return back to starting position. UNSTABLE EQU

Potential free contacts (also known as "dry contacts") are simply contacts which are physically operated with the main device, but not electrically connected to it. For example a m
The device which changes chemical energy into electrical energy is called as electric cell. Battery is a host of constant emf but not constant current.
