    Vectors: why is the cosine of this angle always -1/2?

    how can we (a) Geometrically and (b) Physically(in real life application) interpret the equation ?

    Finding Energy Stored in a Capacitor

    But we also know the charge on the capacitor in steady state. Don't we? Then why is it coming incorrect using this method.

    Finding Energy Stored in a Capacitor

    Homework Statement How to find the energy stored in the capacitor in steady state in this circuit. Homework EquationsThe Attempt at a Solution I found out the charge on the capacitor in steady state using loop law and did energy stored = (Q^2)/2C. but its coming...

    Can Adiabatic Processes Be Irreversible?

    Please help me qualitatively in the following points : 1) If in a system(consider a cylinder) fixed with a piston , if the piston is moved suddenly then how can a process be adiabatic. 2) I understood that the process would be irreversible but, if the process is adiabatic then is the relation...
