Resonance - A mechanical system which is free to vibrate like a hacksaw blade clamped at one end, a diving spring board or the air in pipes has a natural frequency of vibration f 0 , which depends on its dimensions. When a periodic force of a frequency different from f 0 is appl..

The effects of resonance is prominent in conjugated systems (having alternate single and double bonds) wherein displacements of electrons from one part of the molecule to another part takes place, creating centers of high and low electron densit..

When the functional group or any substituent, in aromatic compounds is directly attached to the benzene ring, it is a called nuclear substituted compound. Such compounds are named as the derivatives of benzene under the IUPAC system. However, the common names of many such compo..

. Nowadays other bombarding particles (i.e., projectiles) like protons ( 1 H 1 ), deutrons 1 H 2 electrons can be accelerated to very high speeds by fluctuating electric and magnetic fields in machines such as cyclotron, synchrotron etc. These high speed particles are more efficient in ca..

Nuclear energy is released when very small particles of matter split or combine. After the split or combination, they result in small particles or heavy particle. The rest of the mass is changed into energy. This process of changing mass into energy produces the energy. Energy can also ..

Formation of Our Solar System - Many scientists believe that our solar system was formed from a giant, rotating cloud of gas and dust known as the solar nebula. According to this theory, the solar nebula began to collapse because of its own gravity. Some astronomers speculate th..

Argon is used mainly to provide an inert atmosphere in high temperature metallurgical processes (arc welding of metals or alloys) and for filling electric bulbs. It is also used in the laboratory for handling substances that are air-sensitive. Helium is a non-flammable and light gas. Hence, it is u..

In this, the patient lies down surrounded by massive electromagnets and is exposed to short bursts of powerful magnetic field and waves. These bursts stimulate the protons (hydrogen nuclei) of the patients tissues to emit radio signals which are picked up and converted into digital signa..
