d.) - log 2

thanks for ur gud work again

good work

Congratulations keep going

nishant is correct i blive.2 should be d answer.

Increase your internet speed

Follow these simple steps :

Go to Desktop -> My computer -> (right click on it) -> Manage -> now u see a window of Device Manager

Now go to Ports -> Communication Port (double click on it and Open).

There may be 2 of them Communication Port 1 , Communication Port 2 ,double click on it

Go the Port Settings :--

and now increase ur "Bits per second" to 128000.

and then "Flow control" change to Hardware.

It should immediately increase your internet speed atleast twice.

In case it doesnt please restart and it should work.

I dont know whether it will work but for desktops it must.

I got to know it only a couple of days earlier.So i felt all of us here should benefit from it.

Please rate if you find it useful.

ya quite correct

just after u said mr.polymath i checked up my votes and to my amazement i found that there are 14 hats.A little bit of mathematics will tell u that 14* 5 = 70 How come my altitude be 63 then??? Before falsely accusing people please check the grounds on which ur accusations are based.That will prevent you from embarrassments

this topic was created when some member put in a discussion named "Is this justice" {http://www.goiit.com/posts/list/general-is-this-justice-is-it-right-30051.htm} and in a hot discussion somebody accused chimansu_007 that he is here for rates.The thing rolled on for sometime and we came to the conclusion that there are so many users who are false who dont answer any questions but idiotically rate people.Now this false users just are a burden to this wonderful site.Just as a proof to the fact that i practice exactly what i preach i am going to interact with the administrators and moderators just to ensure that no rates are added to my altitude.And as a matter of fact Mr.Polymath it would be better if you stop wasting ur time as well as mine because time is more precious to me than rates!

I blive u hav a little problem in ur eyesight or maybe a little difficulty in understanding english.Go to the beginning of the post and find out for urself whats written up there.and get this well into ur head that i'm not here for rates.

What will rates give u? will it help u to get into any good college or perhaps the one of your dreams , Mr.Dream_iit???

pls friends help out experts pls do try the quesn. The answer is 7/12 ma^2.This quesn was given in FIITJEE Escape velocity test last year.

What is the moment of inertia about the face diagonal of a cube of mass m and length a ?

CuSO₄reacts wit KI in acidic medium to liberate I₂.

2CuSO₄ + 4 KI = Cu₂I₂+ 2K₂SO₄.

Mercuric periodate Hg₅(IO₆)₂ eacts with a mixture of KI and HCl following the eqn

Hg₅(IO₆)₂ + 34 KI + 24 HCL = 5K₂HgI₄ + 8I₂ + 24KCL + 12H₂O.

The liberated iodine is titrated against Na2S2O3 solutn.1ml of which is equivalent to .0499 gms of CuSO4.5H2O. What volume in ml of Na2S2O3 soln will be reqd to react withI2 liberated from 0.7425 gms of Hg5(IO6)2?

mol wt of mercuric periodate = 1448.5 and mol wt of hydrated coppersulphate = 249.5 gms

How important are rearrengements like Hoffmann Maurtius,Neber,Cope for IIT 08.pls reply frnds and experts.
