We know that for an ideal gas the differential of the internal energy function is: dU = n Cv dT But is Cv the molar heat capacity or not?

Update: Problem solved. Thanks a lot for your time, much appreciated.

So, according to the FBDs we have a force for each object, but again I can't decide if the tension is the same as the weight or the accelerations are the same. I'm completely stuck here.

Okay, so a professor of mine told me that the rope carries the same force from B to A. But same force means different acceleretion if the masses are different. If this is true how can different parts of the rope have different acceleretions if the rope is inextensible?

Absolutely, I just forgot to mention them.

Let's suppose we have a body A with mass M that can move on a horizontal frictionless ground. Now we connect that with another body B, mass m, with the help of a rope. The body B can move vertically and the rope is curved with a pulley. Now we set the body B free to move. What's the relationship...

Update: The math says that the rotating observer measures a force given by: F = mω×(ω×r) which is towards the center of the circular motion. Is that it?

Suppose we have a rotating frictionless disk and there is a rotating observer on the center of it. Furthermore, suppose a very small ball on the disk's edge. Now we clearly know that the ball is not moving but the rotating observer sees the ball following a circular path with an angular velocity...
