Wa eyyakum .. (hope its correct )
E1 / E2 = L1 /L2hey any1 know all the potentiometer formulas
november 2011 V2 X_X, number 32
no 32, y the resultant force is zero ?
No frequency found lower than the 1 of the resonance means, that this is the fundemental harmonic, for tube X, needs a minimum of a quarter wavelength for a resonance, so conider both tubes have a length of 12m for example, so tube X will be 12m, so the stationary wave inside, which is just a quarter wavelength is 12m, so the wavelength will be 12*4 =48m , conisder v (velocity) = 300, so v=f*lamda , 300=f*48, so f=6.25 ...... for tube Y u gotta do the same thing, the minimum wavelength for resonance to occur is half wavelength,, taking the length of the tube as 12, so half wavelength will be 12m, so the wavelength will be 12*2= 24m,, v=f*lamda, 300=f*24, f=12.5,, so the answer will be 2FView attachment 12927

could someone please explain these to me asap! thank you!
for number 15, the drop is falling at terminal speed, so weight = air resistance, retarding force due to air is kv (which can be considered as air resistance), so mg=kv,, v=mg/k ,,, kinetic energy = 0.5mv^2 ,, so u substitute v with mg/k, and u get the answerView attachment 12927

thank u very muchhmmm question 32 is not about the resultant force for nov 11 varient 2. its about electricity-charge
anyway if its that one then here's the solution:
32) look the question said that 8C of charge passes through the 30 ohm resistor in 20sec....
so to find the potential difference, first u need to find current using this formula I=Q/T .....then when u find the current, apply it this formula V=IR ...here R is already known
so V=0.4 x 30 = 12
so answer is C
Hope this helped
sorry I meant november 2011 V1, but okay, thx 4 ur helphmmm question 32 is not about the resultant force for nov 11 varient 2. its about electricity-charge

u r welcumthank u very much
No problemsorry I meant november 2011 V1, but okay, thx 4 ur help
no im the one who is supposed to thnk you..thnk you 4 ur consideration, and its never too late..help is always given for the ppl needed...thnx very muchAoa wr wb!
will try to post second variant of june 2010 inshaAllah
did u solve w09? if yes please give me the link to that post? thanks alott..so we will end with which year??
can u please give me the link to w09 if its solved?Hi all, i've made this thread only for yearly papers starting from june 2002. We'll do 2-3 years each day. And anyone who wishes to help is most welcome. But please once again, this is only for YEARLY papers.
MOD EDIT
