sound energy transformations

Sound is the form of energy propagated as waves which our ears receive. When we speak, our vocal cords vibrate. When we play a guitar, the spring on it makes to and fro motion and produces sound..

Energy is the capacity to do work. All living organisms require energy for carrying on their vital metabolic activities. The primary source of energy for living system is solar radiation. The radiant energy of sunlight cannot be utilised directly by all livi..

Transformer - For a given power requirement, one has the choice of the relative values of I r m s and E r m s . That is, for the product to be a constant, we can choose a relatively large current I and a relatively small potential difference v or just the reverse. In an electric power dis..

(i) Copper loss is the energy lost due to heating of copper coils of transformers. (ii) Iron loss due formation of induced current in the iron line resulting in lot of heat. (iii) Leakage of magnetic flux. All flux linked with primary may not be linked with secondary. (iv) Magn..

The storage and expenditure of energy in an ecosystem is in accordance with the laws of thermodynamics (basic laws of thermodynamics). The first law of thermodynamics is the law of conservation of energy, which says that 'energy can neither be created nor destroyed b..

Introduction - You have learnt that sound is a form of energy. It is produced by vibrations. Sound waves are longitudinal waves. They are also elastic waves hence they need a material medium for their transmission. They can not be transmitted in vacuum. They travel in ..

A ringing bell, a thunderclap, laughter, and rock music are sounds that seem very different to us. However, all sounds are alike because they are waves. Let us understand how wave properties can be applied to sound. Sound is the form of energy propa..

Thus, the total energy is a constant. At the equilibrium position, y = 0 At the extreme position, y = A, As the body oscillates, there is a transformation between kinetic energy and potential energy, maintaining the total energy const..

The figure shows a vibrating simple pendulum, O is the point of suspension. When the centre of gravity of the bob is vertically below the point of suspension, the position of the pendulum is called the rest position or mean position. Let us say that the bob is displaced to a position E 1 . When ..
