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
what is radiant energy?.
Advantages of fibre optics: Fibre-optic communications systems have a large bandwidth, e.g. 1 GHz. The bandwidth is the maximum rate at which information can be transmitted.
What is the work done to take a particle of mass m from surface of the earth to a height equal to 2R (R=radius of earth )? Ans) Initial PE= - GMm/R Final PE = - GMm/3R
Atwood's machine A weight-and-pulley system is used to measure the acceleration because of gravity at Earth's surface through measuring the net acceleration of a set of weight
POSITIVE ACCELERATION: If velocity of a body is enhancing, then its acceleration is said to be positive. The direction of positive acceleration is similar as that of velocity.
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
What are the three particles that make up an atom? Atoms are made up of electrons, protons, and neutrons. The protons and neutrons are found together in the core of the atom, k
A girl starts and finishes the ride at rest. Her horizontal motion can be take as. •an initial uniform acceleration for 3.0s, followed by •a constant speed of 2.4m/s for a further
How does the elevation and air pressure affect the boiling point of water? The only factor that explains the boiling point of water at any altitude is the barometric pressure (
