Which, if any, of the following statements about entropy is/are true? My answers are in brackets...which one(s) did I answer incorrectly? An explanation of why it's wrong would also be helpful. For a process in which Sgen = 0 is a reversible process. [True] Entropy is a measure of...

What I answered is in brackets...what did I answer incorrectly? It is impossible to construct a device that, operating in a cycle, will produce no effect other than the extraction of heat from a reservoir and the performance of an equivalent amount of work. [True] For all naturally...

...can you try to solve it? When I say I have no idea how to do this problem, I mean I really don't get it. Or at least give me a formula/derivation

Homework Statement The figure below shows a pendulum of length L with a bob of mass M. The bob is attached to a spring that has a force constant k. When the bob is directly below the pendulum support, the spring is unstressed. Derive an expression for the period of this oscillating system...
