What is Conductors and insulators
Conductors - one or more electrons from each atom in solid can move freely by body conducting electric charge (metals)
Insulators - electrons are strongly bound to nuclei inhibiting electric charge (plastics, rubber, and glass)
Why is extended source use in Newtown ''s ring experiment?
a) Heat produced is directly proportional to the square of the current passing by a conductor. b) This effect is produced because of collision of free electrons with positive io
A spectrometer is required for creating pure spectrum of a source in laboratory and measuring of ? of material of prism and ? of a transparent liquid. It has of three parts: Col
Explain how receiver functions in fibre optic communication system. Receiver: The optical signal received must be first converted within digital form and in case analog outp
The maximum value of electric field in an electromagnetic wave is 800V/m. Determine the maximum value of magnetic intensity and the average value of pointing vector.
The angular displacement of a body is a function of time and giving by equation h=10+3t+6t square,where t is in seconds.determine the angular velocity, acceleration when t=5seconds
Q. It is possible to have motion in the absence of a force. Yes it is True, in the absence of a force a body will continue moving in a straight line and at a constant velocity
