Can anyone help me on the following problem? I'm not sure how to relate the 90-degree rotation with the rest of what's being asked.
A thin uniform rod is initially positioned in the vertical direction, with its lower end attached to a frictionless axis that is mounted on the floor. The rod...
A uniform spherical shell of mass, M=4.5 kg and radius R=8.5 cm can rotate about a vertical axis on frictionless bearings. A massless cord passes around the equator of the shell, over a pulley of rotational inertia I=3.0*10^-3 kg*m^2 and radius r=5.0 cm, and is attached to a small object of mass...
Are rotational energy levels of a molecule in general equally spaced or does the spacing increase with energy? How about a diatomic molecule; I have seen a derivation showing that the rotational levels in a diatomic molecule are equally spaced, but when drawn in an energy level diagram they...
