Given the following function: def reverse_str(st, pos=0): Returns a new string that is the reverse of st When first called, the pos parameter must be zero if pos == len(st): return "" return reverse_str(st, pos+1) + st[pos] If a user were to call the function like this reverse_str("recursion") What would be the value of pos in the first call? Nothing; an error would occur. 0 "recursion" 1
4 DON Corp. is contemplating the purchase of a machine that will produce net after-tax cash savings of $24,000 per year for 4 years. At the end of four years, the machine can be sold to realize after-tax cash flows of $5,400. Assuming a 9% discount rate, calculate the total present value of the cash inflows and the cash savings from the machine. (FV of $1, PV of $1, FVA of $1, and PVA of $1). (Use appropriate factor(s) from the tables provided. Round final answer to the nearest whole dollar.) Total present value of the cash savings $ 3,826
The Maxwell-Jüttner distribution and the expanding universe The Maxwell-Boltzmann distribution of speeds is the equilibrium distribution of speeds for a distinguishable set of particles, moving with non-relativistic speeds. In this question, you will show that the relativistic form of this distribution - the Maxwell-Jüttner distribution - reduces to the Maxwell-Boltzmann distribution in the limit of low speeds: by this, we mean that the rest mass energy of the particles is much greater than their kinetic energy or k << mc. You will then compare the Maxwell-Jüttner distribution with the Planck distribution for photons in the limit when the particle speeds are highly relativistic so that kT >> mc^2. (a) Show that the Maxwell-Boltzmann distribution, given in terms of speeds, 8 marks f(u)du = 2kT can be written in terms of the magnitude of the non-relativistic momentum p as: f(u)du = f(p)dp = p'dp (Equation 1.1) (b) The Maxwell-Jüttner distribution can be written in terms of the Lorentz factor as: 12 marks f(u)du = K * z * e^(-z) (Equation 1.2) In this equation, K = K(T). The function K(z) is called an Intermediate Bessel function of the second kind. Rewrite equation 1.2 in terms of the relativistic momentum rather than y and z. We will look at the limit where the motion is classical so that kT << mc and therefore z is very much less than 1. Show that your new version of Equation 1.2 reduces to Equation 1.1 in this limiting case. Hints: a) For large arguments z, the function 1 b) The relativistic momentum is p = ymc and the relativistic energy is E = ymc^2 = mc^2 + pc.
