Describe the mechanism of ferromagnetism Ferromagnetism is the basic mechanism by which certain materials (like iron) form permanent magnets or/and exhibit strong interactions
Q. Explain about beta radiation? The second common kind of radiation is beta radiation which consists of high-energy electrons called beta particles (β -particles).
A metal surface is exposed to solar radiations: (1) The emitted electrons have energy less than a maximum value of energy depending upon frequency of incident radiations
The uncertainty in momentum of an electron is 1 x 10 -5 kgm/ s . The uncertainity in its position will be( h= 6.63 x 10 -34 Js) : (1) 5.28 x 10 -30 m
