Oh yeah...relative measurement does make sense. We do start experiments related to conductance by measuring cell constant specific to the cell and so goes for specific conductance. Hopefully the books meant the same as well. Thank you for answering the question sir. :-)

Please anyone can help me?

Thanks tiny-tim for your clarification on the problem... Almost all the books and websites I have referred to don't consider the shape..Maybe they do so secretly ;-) Anyways thanks again.The question was bugging me too much. "a better definition and explanation (of molar conductance, which i...

I have a question about the derivation of the formula for relation between Specific Conductance and Equivalent Conductance i.e. Eq. Conductance = k.V where, k= Specific Conductance ,V=Volume in ml Given link explains the derivation...

I have been trying to simplify the equation but in vain...It is too messy and long. Please let me know if you have a better way. Anyways thanks for assistance. :)

Thanks again.. I tried solving it assuming parameters A and B [P(acosA,bsinA)] and [Q(acosB,bsinB)] Therefore OP.OQ = a^2(cosA)(cosB) + b^2(sinA)(sinB) = 0 Now I simplified it in two ways leading to two equations 1) (b^2+a^2)[cos(A-B)]=(b^2-a^2)[cos(A+B)] 2) -(a^2)/(b^2) = tanAtanB What...

Oh! Interesting...I had failed to notice that and took it as the angle between positive x-axis and the position vector of the point. Thanks Ok, so how do I prove the property then ?

Homework Statement If P and Q are two points on ellipse [(x^2/a^2)+(y^2/b^2)]=1 such that PQ subtends a right angle at the centre O then.Prove that 1/[(OP)^2] + 1/[(OQ)^2] = [1/(a^2)] +[1/(b^2)] Homework Equations Parametric form of points P(acos(θ),bsin(θ))...

Thank you sir/madam for your help.

Homework Statement A metal rod (1/sqrt(pi)) m long rotates about one of its ends in a plane perpendicular to magnetic induction of 5*10^-3 T. Calculate the number of revolutions made by the rod if EMF induced between the ends of the rod is 1.5 mV. I have been thinking about this problem for...

Hello, The line would not change its position by rotating the frame of reference. The motion is the same irrespective of the reference point one takes. For example the moon travels in the same orbit irrespective of where you see it from your location or me from another. (Considering both our...

As the title suggests, there is a practical in which we have to find mass of the spring (m*) having a block of mass M attached to bottom, from GRAPH of time period (T)^2 against M. Here's what the practical handbook says: T^2= [16{(pi)^2}(R^3)N][M+(m*/3)] / [(r^4)n] there is no...

Can anyone explain point 44 of the attached pdf document on surface tension. (Here's the link in case attachment doesn't work: http://www.sakshieducation.com/EAMCET/QR/Physics/Jr%20Phy/12Surface%20tension%20_198-208_.pdf) How is the surface tension direction found out? Also why is...

Nicely answered Sirs. Thank you for helping me sort this problem (it was bugging me continuously :) ) Its seems clear to me right now, I might trouble you guys more later in case I find something incomprehensible. Again thank you.

Thank you guys for the help...:) Its not crystal clear yet but well better than it was before.. So do we take in consideration the 'resistive force' during the process (Pext for expansion and Pint for compression?). Then why isn't work done in pushing a block of mass on ground taken as, say...
