Quantum dot (25 points total) a quantum dot is a small spherical particle (of e. g. cdse) that can trap electrons. for the purpose of describing the behavior of the electron, the quantum dot can be approximated as a three-dimensional spherical box, i. e. the electron is confined to the volume inside a sphere of radius r. the potential is v(r) = o for r r and v (r) = oo for r > r. (c) the function /(r) = n(r -r) with the normalization constant n = /15/(2tr5) is a reasonable approximation to the exact ground-state wavefunction. using /(r), estimate the ground-state energy (d) the exact ground-state energy is 2 mar2is this energy lower or higher than the one you obtained in (c)? briefly explain

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
