On a beautiful summer day‚ one of the most relaxing things to do is watch the steady rise and fall of the ocean waves. Though this motion seems calm and harmless‚ it is‚ in reality‚ a great force of nature. The force becomes even stronger when it is mixed with one of nature’s greatest disasters: earthquakes. When these two great forces collide‚ structure and society are greatly impacted. Though an earthquake can happen at almost anywhere and anytime in the world‚ they all start out in the same way

http://hyperphysics.phy-astr.gsu.edu/hbase/class/phscilab/dens.html Archimedes’ principle states that the buoyant force experienced by a submerged object is equal to the weight of the liquid displaced by the object. Experimentally this appears in the fact that the submerged object apparently weighs less by an amount equal to the weight of the liquid displaced. The buoyant force can be expressed as http://hyperphysics.phy-astr.gsu.edu/hbase/pbuoy.html#arch3 Buoyancy Buoyancy arises from the

CLASSIFICATION OF VIBRATION Vibration can be classified in several ways. Some of the important classifications are as follows. • Free Vibration. If a system‚ after an initial disturbance‚ is left to vibrate on its own‚ the ensuing vibration is known as free vibration. No external force acts on the system. The oscillation of a simple pendulum is an example of free vibration. • Forced Vibration. If a system is subjected to an external force (often‚ a repeating type of force)‚ the resulting vibration

The electricity requirements of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. It is also now widely recognized that the fossil fuels and other conventional resources‚ presently being used for generation of electrical energy‚ may not be either sufficient or suitable to keep pace with ever increasing demand of the electrical energy of the world. Also generation of electrical power by coal based steam power plants or nuclear power plants

Amplitude - the height of a wave from the origin to a crest‚ or from the origin to a trough. Atomic emission spectrum – a set of frequencies of electromagnetic waves given off by atoms of an element; consists of a series of fine lines of individual colors. Electromagnetic radiation – a form of energy exhibiting wavelike behavior as it travels through space; can be described by wavelength‚ frequency‚ amplitude‚ and speed. Electromagnetic spectrum – includes all forms of electromagnetic radiation;
