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.
Can several fibers gives the same amount of light? No, some fibers do not give similar amount of light. If a no. of fibers or light guides are coupled similar illuminator, this
Q. State Brewster's law. Brewster's law the digression of the polarising angle is numerically equal to the refractive index of the medium. That is tan ip = μ
what is this?

A car of mass 800 kg is pulling a trailer of mass 300 kg up the slope of angle ? to the horizontal where sine ? = 1/200. Resistance to motion (apart from gravity) is 1.5 N per kg o
An object located four focal lengths in front of a thin, converging lens is moved to within two focal lengths of the lens. As a result, does the size of the image produced by
As CPH is a boson, does it has structure? Answer; a CPH is tiny energy and it is not a boson. When a CPH takes spin, then it converts to graviton.

What are slide emitting fibers? No, there are not any side-emitting fibers. All fiber optics acquires the light at one end and transport this to the other. While light enters a
Must all illuminator have forced ventilation? Usually yes, the exception being which with a massive construction that dissipate heat by transfer or radiation.
