Bohr given a model for hydrogen molecule which is also applicable for some lighter atoms in which a one electron revolves around a stationary nucleus of positive charge Ze (known as hydrogen like atom)
Bohr's model is based on the following postulates.
(i) The electron can revolve only in particular discrete non-radiating orbits, named stationary orbits, for which total angular momentum of the revolving electrons is an integral multiple of
Characteristics of resistance:- Similar amount of current passed by each resistance i.e. I = I1 = I2 = I3 = I4 ........ The sum of potential difference across individual res

Consider an electron in a simple one-dimensional periodic potential. The energy of the electron will vary periodically due to the influence of the periodic potential, and can be de
The idea that electrons revolved in orbits around the nucleus of an atom without radiating energy away from the atom was postulated by: a) Thompson b) Bohr c) Ruther
Laws of Refraction: There are two laws of refraction. The incident ray, the refracted ray and the normal to the surface of the point of incidence all lie at the similar plan
In 1.0s, 5.0x10^23 nitrogen molecules strike an area of8.0cm^2 at a speed of 300m/s. What is the pressure? (mass of one nitrogen molecule = 4.68x10^-26 kg.) I believe I should use
If the distance between the earth and moon were halved, the force of the attraction between them would be: a) One fourth as great b) One half as great c) Twice as g
What is the raw file size for an image of 80 rows and 100 columns, with pixels on 14 bits and with an extra row for the header? The minimum and maximum values observed in a low
1- Two researchers test the same hypothesis. Researcher A rejects the null hypothesis and researcher B fails to reject the null hypothesis. Discuss three reasons that could cause
