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
If a great point-mass is removed by a weightless, inextensible and perfectly flexible string from a rigid support, then this arrangement is known as a simple pendulum.
show that the oscillation of a liquid in a u-tube is in simple harmonic motion
1. An ionization chamber is used on Tuesday (T=22°C, P=760mmHg) and then on Wednesday (T=25°C, P=740 mmHg) to monitor the output from an x-ray tube. If the output from the tube is
How can time delay between the different modes be reduced? The time delay between the various modes can be reduced when (a) the rays traveling off axis to the fiber are spee
Q Define: specific rotation? Precise rotation for a given wavelength of light at a given temperature is defined as the rotation produced by one-decimetre length of the liquid c
Can you explain acceleration due to gravity?
It having of an evacuated glass or quartz bulb having anode A and cathode C. The cathode is semi-cylindrical solid on which a thin layer of photo-sensitive material is coated.
An object is thrown at 25 m/s at 39 degrees above the horizontal from a 40m tall cliff. How long is it in the air?
Capacitance: If we increase the voltage between the plates, the charge increases, but the ratio of charge to voltage remains the same. This ratio gives the capacitance (C) of
