having problem with mcq no 10 oct/nov 2008.im not getting that howz D the right answer.Need some explanation .
would really appreciate some help .

AsSalamoAlaikum wr wb!

I so wanted to help, but I had biology too...and I coudn't manage it...

JazakAllah Mubarka arlery A.ELWY 7 ....Cud you plz tell me..which one to do...I'll try to do atleast one paper... hope it's not too late yet...

Wa eyyakum .. (hope its correct )
Not at all a problem, it isn't ever too late (unless its after we've appeared for the ppr )
if possible please do 2010, any variant you wish to, cuz there is no ppr of that year here.
Thankyou though.

hey any1 know all the potentiometer formulas

E1 / E2 = L1 /L2

 

[Idolfanatic95]

Please post 2010 solved papers too . .. URGENT!

NOV 10 p12 and JUNE 10 p11 if possible.

november 2011 V2 X_X, number 32

no 32, y the resultant force is zero ?

hmmm 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

could someone please explain these to me asap! thank you!

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 2F

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 answer

sorry I meant november 2011 V1, but okay, thx 4 ur help

 

[Rakayz]

thank u very much

u r welcum

Aoa wr wb!

will try to post second variant of june 2010 inshaAllah

No problem
First of all the resultant can't be downwards. Secondly, its because the force is in one direction...so obviously the resultant for is zero..
The direction is from left to right because the negative charge is attracted by the positive charge, so the resultant torque is anti-clockwise

Hope this helped now!!

 

[Maratib]

now one is answering my question!

Aoa wr wb!

will try to post second variant of june 2010 inshaAllah

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 much

 

[mominzahid]

so we will end with which year??

did u solve w09? if yes please give me the link to that post? thanks alott..

 

[mominzahid]

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

AsSalamoAlaikum Wr Wb!
