Nick, a 60 kg physics student, wants to go bungee jumping, but doesn’t have a bungee cord. He finds
a 15 m long, strong spring (with a spring constant of 60 N/m) in his garage, which he decides should
work just as well. He takes the spring to a nearby bridge, attaches one end to the bridge and the other to
his leg and jumps off. After bouncing around violently for a while, he finally comes to rest. How far
below the bridge is he hanging

Which is the most accurate name for the covalent compound p2o3?

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states

Ahypothetical metal has an orthorhombic unit cell for which the a, b, and c lattice parameters are 0.413 nm, 0.665 nm, and 0.876 nm, respectively. (a) if there are 8 atoms per unit cell and the atomic packing factor is 0.536, determine the atomic radius (in nm). (b) if the density is 3.99 g/cm3, calculate the metal's atomic weight (in g/mol).
