The positron is a positively charged electron. It is an anti-electron - antimatter! The positron consists of a charge of +1 (mere the opposite of -1 of the electron), and a spin of 1/2 as an electron does. Mass of this elementary particle is around 9.103826 x 10-31 kg.
Uncertainty principle (W. Heisenberg; 1927): A principle, central to the quantum mechanics that states which two complementary parameters (like energy and time, position and momentum, or angular momentum and angular displacement) can’t both be r

Gauss' law (K.F. Gauss): The electric flux via a closed surface is proportional to the arithmetical sum of electric charges contained in that closed surface; in its differential form, div E = rho,
When air is compressed adiabatically the law connecting the absolute temperature T and the pressure P is of the form T = A.Pn where A and N are constants. Show by drawing a suitable linear graph that the experimental dat
