but its very difficult to post ..a lots if integration signs ..many changes in limits and long single-lined expressions ( at most 4 I think ..yaaa 4 ) , Last time I came online I tried to post the entire , but my pc got hanged .

yes its right . Its integrable ...the point is there are not many questions of this type in the ncert ..thats why many couldn't do it ...but I did ..I am so happy .

|
yes it should be D and for that H-Bonding question b should be the correct one .

I believe Ken ( Mr.IITIAN007) has given the exact answer .He is right abt his answer and any cutting -shutting will reduce the exact weight of the head as some amount of blood or any fluid in the form of harmones will flow away rapidly before even starting to weigh the head .And subham_sachdeva I can not understand
12p - 12q ?????????????????

Adsorption of a gas on the surface of a solid is generally accompanied by a
decrease in entropy .Still it is a spontaneous process , why ?

An organic compound CxH2yOy was burnt with twice the amount of oxygen needed
for complete combustion to CO2 and H2O .The hot gases when cooled to 0 degree
celcius and 1 atm pressure , measured 2.24 litres .The water collected during
cooling weighed 0.90 gm . The vapour pressure of pure water at 20 degree celcius
is 17.5 mm Hg and is lowered by 0.014 mm Hg when 50 gm of organic compound is
dissolved in water . Calculate the molecular weight of the compound .

In the displacement method , a convex lens is placed in between an object and a screen .If the magnification in the two positions be m1 and m2 and the displacement of the lens between th two positions is X , then foal length of the lens is
a) X / (m1 * m2)
b) X/ |m1 - m2|
c) X/ |m1 + m2|
d) X / (m1-m2)2
