When a spherical body goes by a viscous fluid, it feels a viscous force. The value of the viscous force increases with the enhance in speed of the object falling under the function of its weight. As a result, the viscous force soon becomes the driving force and the object starts rolling with a constant speed, called as its terminal velocity. Let us now produce a relation for the terminal velocity, as an application of stokes' principle.
Describe the construction and working of a rubby LASER with related diagrams?.
(1) Holes works as virtual charge, although there is no charge on holes. (2) Effectual volume of hole is more than electron. (3) Mobility of hole is fewer than electron.
Explain about the term spatial coherence of Laser. Spatial coherence: This coherence is a measure of the correlation among the phases of a light wave at several points’ tran
an object moves along the x axis according -to the equation x(t)=(3t^2-2t+3)m .determine (a) the average speed b/n t=2sec and t=3sec,(b) the instantaneous speed at t= 2s and t=3s (
Volume resistance: The resistance provided to the current which flows through the material is called volume resistance. For a cube of unit dimensions this is called volume resisti
