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
Illustrate the term temperature sensor? Temperature sensor: Bimetal coated onto the tip of fiber. When temperature increases the bimetal bends because of difference within t
A universe is spatially flat, and contains both matter and a cosmological constant. For what value of Om,0 is t0 exactly equal to H0 -1?

Working of a galbanometer?
Two moles of an ideal gas expands reversibly and isothermally to ten times its volume at 25°C. Evaluate the change in entropy during the process. ( R = 8.314 JK -1 mol -1 )
differentiate between direct and indirect band gaps
A particle with mass m = 2:5 is moving along a straight trajectory. The distance covered by a particle is described by the function S(t) = t 3 + 2t 2 , where t > 0 is the time
