    Determining the change of entropy

    Homework Statement A composite system consists of an insulated partitioned volume, shown in Figure 4.9. Side 1 contains 2 mol of a monatomic ideal gas and Side 2 contains 4 moles of the same monatomic ideal gas. Initially, the two sides are separated by a fully insulated partition (adiabatic...

    Transformer current theory problem

    Homework Statement it is a long question so I have attached the question and picture Homework Equations I feel it is more theory based, which I explain below. 3. The attempt at a solution I am unsure- but I would think it is from B to A for part B, as using the RHR, if the coils are wrapped...

    Energy of Oscillations in Clamped String of Tension T

    Okay I couldn't understand why the diagram showed that because i was quite sure KE would be 0, but my prof is foreign and very tough to understand so I must have mixed that up. I'll just hope my prof is there tomorrow because I truly do not understand this and I feel like I'm just getting jerked...

    Energy of Oscillations in Clamped String of Tension T

    So the tension is directed along the string away from where its being pulled? And W=KEfinal-KEinitial. Here I feel like you would have potential energy but no kinetic, but in my diagram from class at the maximum displacement its all kinetic ( if I'm reading it right) so is the kinetic equal to...

    Energy of Oscillations in Clamped String of Tension T

    OKay so my textbook doesn't have examples and I have a very hard time understanding my prof so these are the formulas that I'm thinking may apply somehow: E=KE+U but it says work done against tension so W=Fd=Th? and that's all I can pull out of that. Then I have the standing wave equations so...

    Energy of Oscillations in Clamped String of Tension T

    Homework Statement A string of length L, which is clamped at both ends and has a tension T , is pulled aside a distance h at its center and released. a) What is the energy of the subsequent oscillations? b) How often will the shape shown in the figure reappear? (Assume that the tension remains...
