I give you a hint about what I was actually thinking. 1)\DeltaV=S.y It would mean that \DeltaP is the difference between the initial pressure of the volume considered and the final pressure of the same column (now volume is reduced to (V-\DeltaV) but mass(amount) remains same)...

Let us consider sound (longitudinal) wave y=A.sin(\omegat-kx) See attachment for diagram Consider air column of length \Deltax and cross-sectional area S at distance x from source. I want to derive the pressure equation of the sound wave using Bulk modulus, B=-\DeltaP/(\DeltaV/V)...

\deltaP=Pocos(\omegat-kx) ...(1) B=-\deltaP/(\DeltaV/V) ...(2) \rho=m/V =>\partial\rho=-(m/V2)\partialV =>\partial\rho=-\rho(\partialV/V) =>\partial\rho/\rho=-\partialV/V =>\partial\rho/\rho=\deltaP/B [using (2)] =>\partial\rho=(\rho.Po/B)cos(\omegat-kx) [using (1)]...

Let pressure equation of sound wave be \Deltap=Pocos(\omegat-kx), then what will be the density equation of the sound wave? give your answer with proof and proper explanation...(Derive the equation)

Yes, you are right... Thank you very much for your reply...

please explain with the help of fischer projections...

Both the products you have shown are same, i.e., they have same configuration, though they might have different conformations...

OKAY- got it Thank you

How? C3 is not chiral... please explain what you want to say...

In C1OOH-C2H(OH)-C3H(OH)-C4H(OH)-C5OOH, is C3 stereocentre? >>Will it make any difference if I use the term 'stereogenic carbon' in place of 'stereocentre'?? Please, explain.

I discussed this problem with someone.. He says, lim (sinx)1/x=1 x->0 So, according to him answer must be 2. I worked it out again and got the same answer, i.e., infinity... How is it happening...?? Please, show the steps if you have got the answer 2, 1 or 0. These were the options...

[SIZE="5"][FONT="Trebuchet MS"]Does anybody have any idea about this?? please help...

We see that the fact whether the current increases or decreases too affect the equation by making the induced emf -ve or +ve respectively. How should we assign -/+ signs to current and magnetic field depending on their direction? Is their any convention or any concept?
