Maxwell's Distribution of Molecular Speeds
On plotting a fraction of molecules having different speeds against the speeds of the molecules (along x-axis) a curve known as Maxwell's distribution curve is obtained. ..

Electromagnetic theory of light was put forward by James Clerk Maxwell in 1873. According to this theory, light consists of fluctuating electric and magnetic fields propagating in the form of electromagnetic waves. But this theory failed to explain the photoelectric effe..
Maxwell's Distribution of Molecular Speeds

The rms speed of an oxygen molecule in a sample at 300 K is about 480m/s. This does not mean that the speed of each molecule is 480 m/s. Many of the molecules have speed less than 480m/s and many have speed more than 480m/s. Maxwell derived an equation giving the distribution o..

Imagine a right-handed corkscrew being rotated along the wire in the direction of the current. The direction of rotation of the thumb gives the direction of the magnetic lines of force...
R.D and Archimede's Principle
A solid weighs 50 gf in air and 44 gf when completely immersed in water. Calculate (i) R.D of the solid (ii) upthrust (iii) density of the solid in cgs and SI unit..
One gram weight of force
is the force with which a body of mass 1 g is attracted towards the centre of the Earth. 1 gm wt = 981g /cms 2 = 1 x 'g' dyne [g is acceleration due to gravity in CGS unit..
Gravitational or practical units of force
Another unit of force by which the magnitude of force can be understood and gauged, is the gravitational unit of force. A gravitational unit of force is that force with which the Earth attracts a body of unit mass towards its centre. A gravitational unit of force may also be defined as that force w..
