Auniform thin rod of mass m = 4.17 kg pivots about an axis through its center and perpendicular to its length. two small bodies, each of mass m = 0.519 kg, are attached to the ends of the rod.

what must the length l of the rod be so that the moment of inertia of the three-body system with respect to the described axis is i = 0.913 kgm2?

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?
