1. Derive the equation for the radius of gyration of a cylinder 2. Explain the importance of this concept in dealing with problems concerning rotating bodies
3. describe in detail how you would find find experimentally the moment of inertia of a bicycle wheel about the centre line of it's hub​

Which situation will produce the greatest change of momentum

In an experiment, how can i change human errors? be specific.

An engine undergoes a cycle as shown in the diagram. during a complete cycle the work done by the gas is 28.5×103 j and the energy transferred thermally out is 99.4×103 j. there are 1.5×1024 gas molecules and they have three active degrees of freedom. 6. (6 pts) during which process(es) is energy transferred thermally into the gas? a. 1→2 b. 2→3 c. 4→1 d. 1→2 and 4→1 e. none of the above
