gauss' law for electric field, especially the third question is confused mee. ooh ..hmm E.dA=Q/e0 ok ı know..for shell what can ı do? dQ=RHO*4*Pİ*r2*dr ı didnt understand this equation.isnt rho used for 3D shapes? is shell 2D isn't it?

heyy:cry: I am not an idiot..I tried to solve the first one.. but I don't know true or false,I have some opinions about the third one, but I couldn't understand why rho is given for spherical shell, Isn't is used in volumetric shape (I want to mean that ..for instance rho *4pi/3*r3=Q for...

please help mee, I have an exam tomorrow:cry: 1) Two long,thin cylindirical shells of radii r1 and r2,respectively,are oriented coaxially (one cylindwer is centered inside the other).The cylinders carry equal and opposite linear charge densities lambda ,describe the resulting electric field...

hi , I have problems with thesis statement,(already my eng is not good).ı have a intro paragraph but not thesis maybe one of you wants to help me..ı am writing ..thanks for it. lung cancer kills more people in one year than all criminal and accidental deaths combined. these statics...

hmm . I don't know what gaussian surf. is,why we use this,what determines the gaussian surface's shape..?? :zzz:

hi I have problems with gaussian surface.:cry: is anybody who tell me here?:shy: help me please,thanks :-p

what is your knowledge about carbon ions? is there a machine that determines its creature?

HallsofIvy ,your explanation is very good,thanks a lot

f(x) is not cont at x=2 because f(2)=1 is not equal to lim x->2f(x)=2.I know what continuity is.I don't know how we change the value of f(2) to 2 to be continuous x=2?? and what are the conditions of the continuous extension ?Can be every funct.that is not continuous become cont.?

the book says that g(x)= x ,if x is not equal to 2 / 1,if x=2 has a removable disc. at x =2. I couldn't remove it.I guess I didn't understand a removable dic. completely.I have an exam on friday.I need your help:confused...

ohh thanks a lot.It was easy.

hi, Is anybody who can explain the proof of cosine law here? thanks,:smile:

hımm.I mean that after the certain point(when applied force >the static force) ,the static friction transletes to the kinetic friction.It is true?

yeah..I am confused...in the high school teachers said' friction's and motion's direction are always opposite to each other' now ı know it is not true.all right, when have they the same directions?
