Problem 25P The mathematics of the previous problem can also be applied to a one-dimensional random walk: a journey consisting of N steps, all the same size, each chosen randomly to be either forward or backward. (The usual mental image is that of a drunk stumbling along an alley.) a) Where are you m

Problem 11P IP Three 6.75-kg masses are at the corners of an equilateral triangle and located in space far from any other masses. (a) If the sides of the triangle are 1.25 m long, find the magnitude of the net force exerted on each of the three masses. (b) How does your answer to part (a) change if t

Problem 31P Indium (In) reacts with HC1 to form a diamagnetic solid with the formula InCl2. (a) Write condensed electron configurations for In, In+, In2+, and In3+. (b) Which of these species is (are) diamagnetic and which paramagnetic? (c) What is the apparent oxidation state of In in InCl2? (d) Giv

Urban Economics 8
Consider the effects of housing subsidies on the ?ltering process. As before, assume that each household tolerates up to a 10-unit mismatch between its ideal and the actual quality of housing. All new housing is built for high-income households. Upgrading housing to a higher quality level is prohibit
