Sorry can you elaborate?

Oh! Sorry then. The idea is to take a differential strip(a ring of thickness dr) at a general distance r, find its' M.I and then integrate it to get M.I of the whole disc(a flywheel).

Homework Statement Find the maximum area of a triangle with sides a\in (0,1] ,b\in [1,2], c\in [2,3]. Homework Equations The Attempt at a Solution I tried to make the area as a function of a single variable so that by differentiating I can get the answer. But it was...

Is the answer (9∏\rhoa5 /10) ? If its' correct pls. reply so that i would post my solution.

Hi! STEP 1: convert the alkyne to an alkene using Na/liq.NH3 . STEP 2: Use NBS(N-Bromosuccinimide) to get allyl bromide(CH3CH=CHCH2Br) which when reacted with aq.NaOH gives alcohol(CH3CH=CHCH2OH). STEP 3: Acidic hydrolysis of this alcohol gives the required product. Vineeth.

Ok then what I found out was correct.

Hi!nil1996. Can you give me some information about you like class studying,syllabus(IGSE,CBSE,...),city (or state).

hello! I have to verify the formula of the moment of inertia of an ellipse about its' centroidal axis, is it M*(a^2 + b^2)/4.This is the one I got by myself. But in a webpage it was given as Pi*a*(b^3)/4. NOTE: don't ask for the proof of what I did.Its' a bit longer.I just want to know...

But in this webpage,no general methods of construction of a magic square of any numbers are given. Can you give me a better one ?

Is there any algorithm to form a magic square of any size with a desired magic sum ? Also can we make a magic square not only with the numbers from 1 to n2 but using any random numbers ?

Can anyone give me a situation when the gravitational potential due is 0 but gravitational field is non-zero.

Which is more acidic H2S or H2O?And why?

Then is it confirm that the answer is 281250. But the answer is given as 179550.(source:Problems In Mathematics With Hints And Solutions by V Govrov) Thanks for everyone.

The formal charges in both the cases is zero. In your above formula for FC you wrote the second term as " number of electron pairs ",it should be " number of non-bonded electrons ".

Yes! It is that fraction times p. I have edited it.
