Some ancient objects have been well-preserved in high mountain ranges,
where the concentration of oxygen is low. Otzi the Iceman lived more than
5,000 years ago. Archaeologists found him with his leather pouch, clothes,
and tools perfectly preserved in the ice of the Alps.
Marie's mother lost a leather purse in the yard of their house in Florida, where
the air has more oxygen. Marie found it 30 years later under a tree. It was
rotted and decayed.
Review the information in the data table. What does this information tell you
about the rate of decay reactions relative to the concentration of oxygen?

Consider the particle-in-a-box problem in 1d. a particle with mass m is confined to move freely between two hard walls situated at x = 0 and x = l. the potential energy function is given as (a) describe the boundary conditions that must be satisfied by the wavefunctions ψ(x) (such as energy eigenfunctions). (b) solve the schr¨odinger’s equation and by using the boundary conditions of part (a) find all energy eigenfunctions, ψn(x), and the corresponding energies, en. (c) what are the allowed values of the quantum number n above? how did you decide on that? (d) what is the de broglie wavelength for the ground state? (e) sketch a plot of the lowest 3 levels’ wavefunctions (ψn(x) vs x). don’t forget to mark the positions of the walls on the graphs. (f) in a transition between the energy levels above, which transition produces the longest wavelength λ for the emitted photon? what is the corresponding wavele
