A wheel starts from rest and accelerates with constant angular acceleration to an angular velocity of 15 revolutions per second in 10 second calculate the the angular acceleration and angle which the wheel has rotated at the end of 2 second. 2. A ballad dancer spins with 2.4 revolution per second with her arms outstretched when the moment of inertia about the axis of rotation is I with her arms folded the moment of inertia about the same axis becomes 0.6I. calculate the new rate of spin. 3. An electric fan is turned off and its angular velocity decreases uniformly from 500 revolution per minute to 200 revolutions per minute in 4 second . Find the angular acceleration and the number of revolution made by motor in

Atomic Structure [Normal Revision ]

Atomic Structure (Physics) Thomson's Model Thomson's tried to explain about the arrangement of +ve & -ve charges in an atom. An atom is a +vely charged sphere of diameter about 10 − 10 − 10 m is which +ve charge are uniformly distributed where as -ve charges are slightly embedded like plum in a pudding. This model is also called plum-pudding model. He explained unequal concentration of electric change. Atom is electrically neutral, the concentration of electric charge must be equal. This model could not explain about the atomic stability. This model could not explain about α -particle scattering experiment. Hence, this model is fails to exist Rutherford's Model Rutherford's carried out of α α particle scattering experiment and achieved the following observation. Observation Most of α α -particles cross thin gold foil without any deflection. Some of α α -particles are deflected with particular angle i.e. less than 90 0 0 i.e. acute angle. Few α α -particl
