Practical Applications of Reflection of Sound - Some applications of the principle of Reflection of Sound are: (1) Megaphone, (2) Hearing Board, (3) Sound Board..

Practical Applications of Joule's Heating - This heating is inevitable in any electrical circuit. Since the energy lost by the flowing charges ends up as disorderly thermal motion, the phrase 'ohmic dissipation' is also used to describe it. Often, this is an undesirable effect. For exampl..

Megaphone: Megaphone is a horn-shaped tube. The sound waves are prevented from spreading out by successive reflections and are confined to the air in the tub..

Another unit of force by which the magnitude of force can be understood and gauged, is the gravitational unit of force. A gravitational unit of force is that force with which the Earth attracts a body of unit mass towards its centre. A gravitational unit of force may also be defined as that force w..

This heating is inevitable in any electrical circuit. Since the energy lost by the flowing charges ends up as disorderly thermal motion, the phrase 'ohmic dissipation' is also used to describe it. Often, this is an undesirable effect. For example, in electric circuits, the heat produced in a small ..
