    Volume of a cone covered with a plane

    Homework Statement I need to find the volume of a cone covered with a plane z=h using multiple integrals. The scheme is something like this: Homework Equations Formula of the cone x^2-y^2-z^2=0 The Attempt at a Solution I tried to integrate ∫∫∫(x^2-y^2-z^2)dxdydz in all...

    Momentum values in quantum mechanics

    The first part of your reply was just what I was expecting, so thank you for that. I have given all the information concerning the problem, so I don't know if I can express it in terms of eigenfunctions, in case I haven't missed anything. Can you help me formulate an answer, what are the values...

    Momentum values in quantum mechanics

    Homework Statement In an infinite potential hole, the ground state is described by the wavefunction ψ=A*sin(\frac{πx}{a}). Does the ground state have a definite momentum? If not, then what are the values of momentum in ground state? Homework Equations Wavefunction ψ=A*sin(\frac{πx}{a})...

    Complex impendance in RL circuit

    Homework Statement I have to show that the impendance of a parallel RL circuit would be the same in measure as the impendance of a non-parallel RL circuit (sry, don't know how to express this in English). I have to show this so that the inductivity stays the same in both cases but the...
