In year 0, javens inc. sold machinery with a fair market value of $450,000 to chris. the machinery’s original basis was $355,500 and javens’s accumulated depreciation on the machinery was $55,000, so its adjusted basis to javens was $300,500. chris paid javens $45,000 immediately (in year 0) and provided a note to javens indicating that chris would pay javens $67,500 a year for six years beginning in year 1. what is the amount and character of the gain that javens will recognize in year 0? what amount and character of the gain will javens recognize in years 1 through 6?

If the speed of a particle triples ,by what factor does its kinetic energy increase?

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

What is the stall speed at sea level of an airplane that weights 10000 lbs., has a wing area of 300ft^2, and a maximum lift coefficient of 1.4? what is the stall speed if flaps that double cl, max are applied?
