    3) Y = Ae^-kx^2 ln Y = ln A - kx^2 ln Y = -kx^2 + ln A This is now rearrange into Y = mX + C form. So k = gradient ln A = y intercept.

    Thanks a lottttttttttt!! ^_^ Do u have more notes??? :D This concetric ring I never found in my text book. From where did u get? Can I get notes on hall probe? How De broglie wavlength and radius is related?

    Crms is proportional to sqrt(T) Crms1/Crms2 = sqrt(T1)/sqrt(T2) 500/1000 = sqrt(300)/sqrt(T2) T2 = 1200K

    It depends from person to person. I had a friend who gave 6 subjects in 6 months and scored 6A*s and a friend who is giving just As level since 2 years and yet he is stuck at D. So now as I said, it depends. If you love studying and your complete focus is in studies and wanna score good u need...
