2. Let D be a relation on the natural numbers N deﬁned by D = {(m,n) : m | n} (i.e., D(m,n) is true when n is divisible by m. For this problem, you’ll be proving that D is a partial order. This means that you’ll need to prove that it is reﬂexive, anti-symmetric, and transitive. (a) Prove that D is reﬂexive. (Yes, you already did this problem on one of the minihomework assignments. You don’t have to redo the...

extra credit1 A 2-source dipole system has two in-phase sound sources located at (0, d/2) and (0, -d/2). Given a sound detector using displacement pressure detection principle, basically a force vector measurement perpendicular to the propagation wave vector of a single sound source, find the total signal intensity expression as a function of distance along the x-axis at large distances, >> wavelength, >> d, when a 1-source system would generate displacement (b/r)sin(k(r - vt)) . Use the binomial expansion to find...

a power plant treats 2 ML/d of feedwater to remove total organic carbon (TOC). The source water contains 30 mg/L of TOC. The treatment system consists of a square coagulation and flocculation tank that with a removal efficiency of 30% TOC (because organic matter sticks to floc). The coagulation tank is followed by a long (20 m), narrow(2 m) ozonation channel of 100,000 L with TOC degradation rate of 1.73/hour by reaction with ozone. What is the TOC concentration at...
