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
An ideal Brayton cycle uses air as a working fluid. The air enters the compressor at 101 kpa and 37 C. The pressure ratio of the compressor is 12:1, and the temperature of the air
A guitar string produces 4 beats/second when sounded with a250Hz tuning fork and 9 beats/second when sounded with a 255 Hz tuning fork. What is the vibration frequency?
Gauss' law for magnetic fields The magnetic flux by a closed surface is zero; no magnetic charges present. In differential form, div B = 0.
why do electric field lines contract longitudinally
