Rutherford's alpha-scattering experiment recognized that the mass of atom is concentrated with small positively charged region at the centre which is known as 'nucleus'.
Nuclei are made up of neutron and proton. The quantity of protons in a nucleus (known the atomic number or proton number) is shown by the symbol Z. The number of neutrons (neutron number) is represented by N. The total quantity of neutrons and protons in a nucleus is known it's mass number A so A = Z + N.
Neutrons and proton, when explained collectively are known as nucleons.
Nucleus have two types of particles : Protons and neutrons
Light is normally incident on a thin soap film and is reflected. If the wavelength of this light is "L" and the index of refraction of the soap film is "N", complete destructive i
Give two basic important characteristics of nuclear forces? Neutrons are the best projectiles of process of nuclear reactions. Why? Give any two properties of neutron.
A radioactive substance has a half life of 1 min. If one nuclei decays now , when will be next decay????
Does CPH mass increase? Answer; Never, mass of CPH is constant, as like its speed.
Infrared Waves: Infrared wave also known as heat wave. These waves are radiation by hot body at dissimilar temperature.

Tesla; T (after N. Tesla, 1870-1943): The derived SI unit of magnetic flux density, described the magnetic flux density of magnetic flux of 1 Wb by an area of 1 m 2 ; thus it
What is fusion? It is a nuclear reaction in which two nuclei join to form larger (with nearly combined mass) nuclei. It discharges lot of energy. Sun and stars discharge energy
