cumulative relative frequency

Summary - With increasing complexity, the organisms have had to develop means of control and coordination between the different parts of the body. Coordination is necessary for acting as one unit and to maintain the homeostasis or steady state within the body. Control and coordination in animals is..

Intensity and Loudness of Sound - Physically, a wave involves the propagation of energy. This transfer of energy by a traveling wave is expressed in terms of the intensity I. Intensity of sound waves is defined as the average energy transported per second per unit area perpendicular to the directio..

. Further, as electron would lose energy continuously, the atoms should emit electro-magnetic waves over a continuous range. But atoms emit only discrete frequency wavelengths only. From alpha ray scattering experiment, Rutherford calculated distance (r o ) of closest approach of a - part..
