For any variable X, ΔX = “change in X ”, Δ is the Greek (uppercase) letter delta, Examples: If ΔL = 1 and ΔK = 0, then ΔY = MPL. More generally, if ΔK = 0, then Δ(Y − T ) = ΔY − ΔT , so ΔC = MPC × (ΔY − ΔT ) = MPC ΔY − MPC ΔT Now Suppose MPC = 0.8 and MPL = 20. For each of the following, compute ΔS: a.ΔG = 100...

Two protons are initially moving towards each other with equal speeds in the laboratory. They continue to exist after experiencing a head-on collision that also produces a neutral pion of rest energy 135 MeV. If the protons and the pion are all at rest after the collision, find a) the initial kinetic energy of the protons, and b) the initial speed of the protons.

Suppose you’re evaluating a new project costing 125 and yielding an expected payoff of 75 for the two subsequent years. You know that the market(portfolio) rate is 0,10 that the covariance of the new investment’s payoff with the market portfolio is 0,2 and that the variance of the market payoff is 0,1. You also know that the risk-free rate is 0,05. Would you accept the project if you do not account for the risk embodied in the new project? Why?...

A medical researcher believes that a drug changes the body's temperature. Seven test subjects are randomly selected and the body temperature of each is measured. The subjects are then given the drug, and after 30 minutes, the body temperature of each is measured again. The results are listed in the table below. Is there enough evidence to conclude that the drug changes the body's temperature? Let d=(body temperature after taking drug)−(body temperature before taking drug). Use a significance level of...

For one approach to this problem, consult Interactive LearningWare 24.1. For each of the three sheets of polarizing material shown in the drawing, the orientation of the transmission axis is labeled relative to the vertical. The incident beam of light is unpolarized and has an intensity of 1230 W/m2. What is the intensity of the beam transmitted through the three sheets when 1 = 15.2°, 2 = 53.2°, and 3 = 95.4°?
