    Why Does Heat Stop Flowing When Q=TS in Thermal Equilibrium?

    Hey, Equilibrium is of various types, like mechanical , thermal, chemical etc. When we speak of it in general we mean all the above are satisfied meaning the two bodies are in thermal equilibrium as well. in fact the Helmholtz and Gibbs equations are obtained for the conditios that The...

    Same pinch :P I said the same thing :-)

    Derivative of log/exponential functions

    Hey, don't think it that way. I think Wolfram Alpha is the best site for mathematic calculations.It can do integrations as well In fact in your answer, look at the first block at the lower right corner.Tou can see that its stated log is natural logarithm :-)

    Derivative of log/exponential functions

    I hope it's clear now. ln is to the base e where as log is to the base 10. Also log(a/b)= log(a)-log(b) Not log(a)-log(1/b). This rule can be derived using basic definition of log function. NOTE :I HAVE EDITED THE QUOTE A LITTLE

    Emailanmol's discussion on angular displacement

    NOTE : I had edited my previous post a bit, but it changes the meaning in no way :-) ---- Ok, thanks K2 . I will go through the wiki page.

    Emailanmol's discussion on angular displacement

    Hello K2, Thanks for your reply :-) Actually this isn't my statement. It's from Resnick halliday krane where they say that for small angles its true even in 3d You can view the pages of the book from the links i posted http://imageshack.us/g/85/img0390nv.jpg/ I think that this...

    Emailanmol's discussion on angular displacement

    I completely agree that once a quantity has been defined , mathematically it includes the information if it is a vector or scalar (or anything else), and in fact my experiment is loosely based on taking advantage of this fact. You are getting me wrong which is causing a bit of...

    Emailanmol's discussion on angular displacement

    Your welcome :-) In case you still have doubts, open the FIITJEE package or RSM and confirm that the book states and makes exactly the same point as me. I have been a part of FIITJEE for a significant span of time now, and know on what logic the question was based and why it was given as a...

    Emailanmol's discussion on angular displacement

    So you mean to say the statement and proof in the book is wrong? Here's a thread where the last guy speaks of exactly the same thing. https://www.physicsforums.com/showthread.php?t=279292 I think there are two versions going here.Perhaps treating it as a vector is more of a...

    Why Does Heat Stop Flowing When Q=TS in Thermal Equilibrium?

    What happens during a reversible process? How are the temperatures(or some other quantities like pressure) of system and surrounding related during each step in such a process? (Hint: It has something to do with equilibrium.)

    Emailanmol's discussion on angular displacement

    Hello cepheid and Tiny Tim, First of all I would like to point out that any comments I have made (or will make ) so far are just to continue a discussion on a healthy basis and to find out what is actually the right answer to my doubts. My aim is to learn as much as possible from the two of...

    Emailanmol's discussion on angular displacement

    Precisely my point. You CHECKED if the angular displacement is scalar by subtracting the angles. Not by stating it as a scalar in first place. In a more accurate way, for angular displacement we rotate objects along some steps and then reverse the chronological order of these steps and...

    Emailanmol's discussion on angular displacement

    Ok, So on what basis, did we come to know that the average angular displacement is not a vector . Whereas instantaneous angular displacement is a vector.? We defined pressure as force per unit area. How did we come to know if the combined pressure at a point added as a scalar and not...

    Emailanmol's discussion on angular displacement

    Hey, It's not just a matter of DEFINITIONS.Usually, we never define a quantity as a vector or scalar in the first place. We define them as a property of the system. Like angular displacement was defined as the rotating angle and then put to test against the laws of vector addition. It...

    Electric Potential of three concentric spheres

    No.The figure clearly shows these are three concentric solid conducting spheres.(not shells). That is all three are virtually in contact. I in fact fail to get why there would be any charge on sphere A and B.It should all move to the surface C and reside there. However, those are the...
