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
1. Fill a sink or bath tub with water. 2. Practice tapping the cork on the surface of the water (about 3 _times per second works well) to create evenly spaced waves. 3. Tappi
In the SI system of measure, what is the unit of capacitance? Ans: In the SI system of measure, farad is the unit of capacitance.
A capacitor is to be constructed so that its capacitance is 0.2µF and to take a p.d. of 1.25kV across its terminals. The dielectric is to be mica which, after allowing a safet
