QA particle performs harmonic oscillations along the x axis
according to the law x= a cos wt. Assuming the probability P of
the particle to fall within an interval from --a to +a to be equal to
unity, find how the probability density dP/dx depends on x. Here
dP denotes the probability of the particle falling within an interval
from x to x+dx. Plot dP/dx as a function of x. ?????

LOCKERZ !!!! IT REALLY REALLY WORKS................

Mon, 22 Mar 2010 08:18:21 +0530

HI GUYS
WONDERING WHAT LOCKERZ IS......???
IT'S A BASICALLY A WEBSITE WHERE YOU CAN GET A CHANCE TO WIN AN IPOD, XBOX360, SONY PLAYSTATION, APPLE MAC BOOK, AND LOTS OF OTHER GADGETS.
THE ONLY THING ONE NEEDS TO DO IS TO EARN PTZ AND THERE ARE A COUPLE OF WAYS TO DO THAT. HOWEVER, THE SITE IS SO MUCH POPULAR THAT IT CAN ONLY BE ACCESSED THRU MEMBERSHIP AND I HAV SOME LIMTED INVITES AVAILABLE. SO IF U WANT TO BE THERE, KINDLY MAIL ME UR EMAIL ID SO THAT I CAN SEND U AN INVITE.
REMEMBER GUYS, THIS IS NOT A SPAM. I M A CLASS 12TH STUDENT IN DELHI.
AND I M 100% SURE THAT U'LL THANK ME LATER ON.
YES, ONE THING MORE, I RECENTLY WON AN IPOD NANO FROM LOCKERZ N AM NOW AIMING FOR XBOX 360...

THANX.............:)

1)A:Alkali metals form ionic hydride .
R:Alkali metals have low EN,their hydrides conduct electriicty when fused and liberate H2 at anode

2)A:Dipole moment of pyridine >pyrrole but in opp direction
R:In pyrolle N atom contributes 2 electrons for delocalized pi orbital but this is not true for pyridine

3)A:Addn of AgNO3 to aq KI gives -ve sol wheras add of KI to AgNO3 gives +ve sol of AgI

R:Sol particles adsorb common ions present in sol acquire their character

which process ?????????????

The earth bulges slightly at the equator, due
to the centrifugal force in the earth's rotating frame.
Show that the height of a point on the earth (relative
to a spherical earth), is given by

where is the polar angle (the angle down from the
north pole), R is the radius of the earth and is the
earth's angular speed of rotation about its own axis.

1) Equimolar quantities of each of the following substances are dissolved in enough water to make 1 L of solution. Arrange the solution so prepared in order of increasing pH.
(a) KHSO₄ (b) NaHCO₃ (c) Na₂O (d) HClO₄ (e) CH₃ NH₃ Br

2) Calculate the pH of a 0.15 M aqueous solution of AlCl ₃ , Given:-

[Al (H2O)₆] ³⁺ + H₂O (l) → [Al (H₂O)₅ OH]²⁺ (aq) + H₃O⁺ (aq) ......K_a= 1.4 X 10^-5

3) Find the pH of the solution obtained when 25 mL of 0.005 M benzylamine is titrated to the equivalence point with 0.005 M H Cl. pK_b of benzylamine is 9.33

4) 10 mL of 0.1 M CH₃COOH (pKa = 4.74) is titrated with 0.1 M NaOH. What is the pH when :-
(a) 5 mL of NaOH has been added
(b) 10 mL of NaOH has been added

well one after a LONG LONG time...first time ever in chemistry!! grossly conceptual though!! may be easy!!

A DIAMOND MOLECULE IS LARGER IN SIZE THAN A CARBON ATOM...SAME FOR MANY...WELL LETS LOOK IN THE CASE OF HYDROGEN...HYDOGEN MOLECULE IS SMALLER IN SIZE THAN HYDROGEN ATOM..TRUE or FALSE...STATE THE REASON...

DISCLAIMER: The question is to confuse a very easy concept!![3][3][3][3]

this may be called a hint but this is a crooked hint!![3][3][3][3]
