Homework Statement Homework Equations and the attempt at a solution:[/B] AC is adiabatic and AB is isothermal. Heat absorbed during process AC = 0 (adiabatic). Heat absorbed during process CB = C_p \triangle T=-\frac{\gamma}{\gamma -1} (P_2V_3 - P_2V_2) Heat absorbed during process BA =...

@kuruman : Thanks for the help. Maybe I should not be too rigorous about the pointed cones. If I round off the cones a little, then A will be a concave surface and B will be a convex surface. It looks like the charges would be crowded at B compared to A. Therefore B has a lesser charge density...

1. Homework Statement : Homework Equations :[/B] A conductor is an equipotential surface. The charge density near a conductor is proportional to the electric field. Electric field is the negative gradient of potential and thus electric field is in a direction normal to the surface.The Attempt...

Yes I have. I have used that formula on the left side of my workout. The answer is not there among the options.

The following question has stumped me. I am not getting the answer marked. Instead I am getting option a). I have produced my attempt below. Also I have no idea which formula to use when the question says Doppler width. Since frequencies form a distribution, there are multiple notions of width...

Thanks for that clarification. If it is classical, how has the total energy increased?

How did you know that it is a classical momentum problem apriori? The energies of the two pieces are 8GJ and 2GJ. I have updated my original post.

This question was asked in an competitive exam in India. The relevant equations are momentum conservation in the classical sense and the 4 momentum conservation. My attempt: Classical momentum conservation would seem inaccurate since the kinetic energies are high. However, a straightforward...

hello all, My name is Srikanth. I am from India and I am 30 years old. I have a ph.d disassertation in the area of error correcting codes. I am awaiting the award of the degree. However I spend most of my time reading the fascinating connections between mathematics and physics. I teach physics...
