THOMSON'S ATOMIC MODEL:-
According to Thomson's atomic model positive charge is distributed uniformly over the entire body of the atom while the electrons are embedded in it. Similar to the seeds in a water melon.
Thomson's model failed to explain observed spectra emitted by an atom .
In a certain cathode-ray tube, a beam of electrons, moving at a constant velocity, enters a region of constant electric force midway among two parallel plates that are 10.0 cm long
a) Thomson's heat is proportional to the current passing by the conductor. b) This effect is produced when parts of similar conductor are kept at dissimilar temperature. c) I
