11q3 refractive index of water shud be given ...it was 4/3
3) 1/f = (u - 1) (1/R1 - 1/R2)
so 1/fa1/fw = (ua - 1)(uw -1)
or fwfa = (ua - 1)(uw -1)
so fwfa = 1.5 - 11.5/(4/3) - 1 = 4
so fw = 4 fa = 4 x 8 = 32 cm
13Cleanliness does not imply Hygiene, though Hygiene does imply Cleanliness.
Fr more Clarification, WiKi says-
"Hygiene refers to the set of practices associated with the preservation of health and healthy living."
So, me going with (D) too.
4D - 3
C -2
@Pritish : I was just kidding ya
I already said in #8 which one I feel more logical
But ans given C So just w8ing 2 c if I've mistaken :(
39Now now don't decide by vote. Decide by the clearest logic you can get, this is a logical question!

4@Avik : U r √ . Thanks
(Actually 2 , 3 ,4 were not doubts but i had a prob with the ans given So i posted)
But ya thanks everyone
13(2) More the value of "i", Lower the freezing point will go. (Concentrations are the same, so is the solvent.)
Which implies ...(A).
4@Organic : Y do u think it is C?
I mean I think D coz awareness and consiousness r synonyms like the pair in qs
But Laugh n Joke r not syns
and moreover Laugh is verb and Joke may be taken as Noun or Verb
114)a actually they are asking for the total charge in the circuit...
the individual charges come out to be 400 mu C and 900 mu C
so total charge in circuit which flows = 900 + 400 = 1300 mu C
4(4) A 3muF capacitor is charged to 300 V and a 2muF cap is charged to 200 V.The caps r then connected in parallel with the plates of opposite polarity joined together.What will be the amount of charge that will flow when the plates r so connected??
(A)1300 mu C
(B) 600 mu C
(C) 250 mu C
(D) 700 mu C
4(3) A convex glass lens (mu = 1.5) has a focal length = 8 cm when placed in air

(B) 4
(C) 16
(D) 32
4(2)Which of the following has minimum freezing point ?
(A) 1 molal Cacl2 solution
(B) 1 molal Urea solution
(C) 1 molal Nacl solution
(D) 1 molal Kcl solution
