LENARD ATOMIC MODEL:
Lenard suggested that the atom must have a lot of empty in it.
Lenard's model of an atom could not explain about the stability and mass of an atom .
a beam of electron is incident on barrier 6eV high and 0.2 nm wide. find the energy in eV these should have if 1% of them are to get through the barrier.
Disadvantages of D.C. Transmission of power 1. Electric power cannot be produced at high d.c. voltages because of commutation problem. 2. The d.c. voltage cannot be stepped
what is motion
Q. Define: Thomson effect. Thomson recommended that when a current flows through unequally heated conductors heat energy is absorbed or evolved throughout the body of the meta
Photomultiplier tube(PTM) it can detect a weak flash of light and estimate the amount of light .The principle of operation (fig(4)) a light photon released electron at the phot
unlike Parallel forces
Coulomb: Coulomb is the fundamental unit of charge. It is explained as the charge required to obtain 9?109 newton of force among two equal charges separated at a distance of one m
how to transform series to parallel
Light propagates as transverse EM rays. The magnitude of electric field is much larger as compared to magnitude of magnetic field. We generally prefer to define light as electric f
