What is Scattering. Explain using formulas, diagrams and what applications it can be used for
(a) Explain what it means for a particle to be "off-shell". [1] (b) In a scattering experiment, an electron and positron are elastically scattered off each other. Show that there are two tree-level Feynman diagrams that contribute to this process, with photons as the exchange particle. [2] (c) By considering the conservation of energy and momentum, show that the exchange particle in both of your Feynman diagrams must be off-shell. (Hint: work in the centre of mass frame.) [4] (d)...
(i) Describe with appropriate diagrams, the concept of Raman scattering spectroscopy. Name 2 primary differences between Raman and Infra-red spectroscopy. What is the fundamental property of a molecule that is probed by Raman scattering? [6 Marks] (ii) What are the three possible deviations from the Beer Lambert law? Explain why they might arise. Give an example using chemical equations of a deviation in the Beer Lambert Law due to a chemical shift. [
5 hapter 4 Problems and Applications 1. Explain each of the following statements using supply-and-demand diagrams "When a cold snap hits Florida, the price of orange juice rises in supermarkets throughout the country." "When the weather turns warm in New England every summer, the price of hotel rooms in Caribbean resorts plummets." "When a war breaks out in the Middle East, the price of gasoline rises and the price of a used Cadillac falls a. b. C.

Error Proofing using Vision system can provide several error proofing applications, what applications?
Explain what Pourbaix diagrams show and how they are derived along with the assumptions used.
Question 1 1.1 Discuss the applications of automated production lines and give examples. 1.2 Using diagrams, discuss the fundamentals of automated production lines.
(a) Explain using diagrams how monopoly power can impose costs on society. (b) If the gains to producers from monopoly power could be redistributed to consumers, would the social 5. cost of monopoly power be eliminated? Explain. (c) What can the government do to reduce the social costs of monopoly?
Directions: Show all work including steps used during computations using formulas and diagrams when appropriate. Write a DETAILED statement explaining the meaning of your computations (conclusions) for all problems- hypothesis tests and confidence intervals. Remember that the conclusions for hypothesis tests need both a statement about the null and alternative hypotheses and another sentence or two describing how that applies specifically to the context given in the question. 1. A recent poll of 500 registered Democrats found that 315 of...
Describe five real-world applications in which regression can be used. For each of these applications, describe the y-value and the corresponding feature vector X. Also discuss whether linear regression can be used in each case.
