1. Treacherous Triangle Trickery. Consider a charge distribution consisting of an equilateral triangle with a point charge q fixed at each of its vertices. Let d be the distance between the center of the triangle and each vertex, let the triangle’s center be at the origin, and let one of its vertices lie on the x-axis at the point x = −d. 1.1. Compute the electric field at the center of the triangle by explicitly computing the sum of the...

One design for a solar furnace is based on the paraboloid formed by rotating the parabola x2=3y around its axis of symmetry. The object to be heated in the furnace is then placed at the focus of the paraboloid (assume that x and y are in units of feet). How far from the vertex of the paraboloid is the hottest part of the furnace? Express your answer as a fraction or a decimal rounded to two decimal places. Please show...

A confectioner sells two types of nut mixtures. The standard-mixture package contains 50 g of cashews and 120 g of peanuts and sells for $1.95. The deluxe-mixture package contains 100 g of cashews and 40 g of peanuts and sells for $2.25. The confectioner has 15 kg of cashews and 18 kg of peanuts available. On the basis of past sales, the confectioner needs to have at least as many standard as deluxe packages available. How many bags of each...

The Fraud Triangle LO 5-2 Explain the components of the Fraud Triangle. Donald R. Cressey, a noted criminologist, is mostly credited with coming up with the concept of a Fraud Triangle. Albrecht points out that, while researching his doctoral thesis in the 1950s, Cressey developed a hypothesis of why people commit fraud. He found that trusted persons become trust violators when they conceive of themselves as having a financial problem that is nonsharable, are aware that this problem can be...

A barbell spins around a pivot at its center at A. The barbell consists of two small balls, each with mass 450 grams (0.45 kg), at the ends of a very low mass rod of length d = 50 cm (0.5 m; the radius of rotation is 0.25 m). The barbell spins clockwise with angular speed 120 radians/s. We can calculate the angular momentum and kinetic energy of this object in two different ways, by treating the object as two...

Programming can be used to assist users in completing complex calculations very quickly. As seen in class practices, we were able to calculate the area of geometric shapes, figure out the number of calories in cookies, and even calculate a restaurant bill. For this assignment, you will take input from the user to provide interactive messages and to solve the following word problem: Engineers often need to convert between different types of units to perform calculations that follow standard formulas....

It has often been suggested that elements in our environment can provide cues for recalling past information. For example, a hypothetical study examined the effect of a specific perfume scent on students’ abilities to recall a set of objects. A random sample of 18 subjects was randomly assigned to one of two conditions: 1) Nine subjects memorized and then recalled a set of objects while a scent was present in the air. 2) The other nine subjects memorized and then...
