7. Average age in a population. Suppose the 100-vector a represents the distribution of ages in a population, with xi being the number of i-1 year olds, for i = 1, . . . , 100. Find an expression for the average age across the population. (You can assume that xメ0) Your expression must use vector or matrix notation; you cannot use a sum over ages You can use any notation we've encountered, including vectors, matrices, matrix-vector products, inner product,...

question 7 and 8
Purpose To examine the properties of polarized light and the mathematical relationship describing the intensity of linearly polarized light (Malus'law). In addition, the lab will investigate different ways light can be polarized Overview This lab is the first of three labs exploring the properties of electromagnetic waves. Electromagnetic waves are composed of oscillating electric and magnetic fields. As discussed in the lecture the electric and magnetic field vectors are mutually perpendicular to each other. Light waves...

A. Issues [1] In addition to damages for one year's notice period, can a trial judge award significant damages for the mere fact of an employee's dismissal, or for the stigma that that dismissal brings? Or for the employer thereafter competing with the ex-employee for the clients, before the ex-employee has got a new job? B. Basic Facts [2] This is an appeal from 2009 ABQB 591 (CanLII), 473 A.R. 254. [3] Usually a judgment recites facts before law. But...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
