light year is the unit of distance..not light plz correct sir
Is the magnitude of one charge constant (1.6x10*-19)? If so, then by Coulomb's law, can the force be changed only by a change in distance?
If pdf is there please send me 9738407757 whatsapp number ...i am preparing for physics teacher exam ...help me sir thank you sir
@akki: the impurities added to semiconductors don't always provide free electrons eg impurities of 15th group.
Thanks for keep in touch with us. I have resolved all problems.
Metal is good conductor of electricity because of more free electron
Earth is rotate from west to east so stars looks like rotate east to west
And the capillary tube with unequal length the presure are not maintained so the water fill not flow
And semiconductor main impurity conductivity ko increase karta hai because of more free elctron
