Assignment 1: Coulomb’s Law Due: 8:00am on Wednesday, January 11, 2012 Note: To understand how points are awarded, read your instructor’s Grading Policy. [Switch to Standard Assignment View] Coulomb’s Law Tutorial Learning Goal: To understand how to calculate forces between charged particles, particularly the dependence on the sign of the charges and the distance between them. Coulomb’s law describes the force that two charged particles exert on each other (by Newton’s third law, those two forces must be equal and opposite). The force exerted by particle 2 (with charge ) on particle 1 (with charge ) is proportional to the charge of each particle and inversely proportional to the square of the distance between them: , where and is the unit vector pointing from particle 2 to particle 1. The force vector will be parallel or antiparallel to the direction of , parallel if the product and antiparallel if ; the force is attractive if the charges are of opposite sign and repulsive if the charges are of the same sign. Part A Consider two positively charged particles, one of charge (particle 0) fixed at the origin, and another of charge (particle 1) fixed on the y-axis at . What is the net force on particle 0 due to particle 1? Express your answer (a vector) using any or all of , , , , , , and . ANSWER: = Correct Part B Now add a third, negatively charged, particle, whose charge is (particle 2). Particle 2 fixed on the y-axis at position . What is the new net force on particle 0, from particle 1 and particle 2? Express your answer (a vector) using any or all of , , , , , , , , and . ANSWER: = Correct Part C Particle 0 experiences a repulsion from particle 1 and an attraction toward particle 2. For certain values of and , the repulsion and attraction should balance each other, resulting in no net force. For what ratio is there no net force on particle 0? Express your answer in terms of any or all of the following variables: , , , . ANSWER: = Correct Part D Now add a fourth charged particle, particle 3, with positive charge , fixed in the yz-plane at . What is the net force on particle 0 due solely to this charge? Hint D.1 Find the magnitude of force from particle 3 Hint not displayed Hint D.2 Vector components Hint not displayed Express your answer (a vector) using , , , , , , and . Include only the force caused by particle 3. ANSWER: = Correct Exercise 21.4 You have a pure (24-karat) gold ring with mass . Gold has an atomic mass of and an atomic number of . Part A How many protons are in the ring? ANSWER: = 4.27×1024 Correct Part B What is their total positive charge? ANSWER: = 6.83×105 Correct Part C If the ring carries no net charge, how many electrons are in it? ANSWER: = 4.27×1024 Correct Exercise 21.22 Two point charges are placed on the x-axis as follows: charge = 4.05 is located at 0.197 , and charge = 5.00 is at -0.296 . Part A What is the magnitude of the total force exerted by these two charges on a negative point charge = -6.00 that is placed at the origin? ANSWER: = 2.55×10−6 Correct Part B What is the direction of the total force exerted by these two charges on a negative point charge = -6.00 that is placed at the origin? ANSWER: to the + direction to the – direction perpendicular to the -axis the force is zero Correct Problem 21.66 A charge 4.97 is placed at the origin of an xy-coordinate system, and a charge -1.99 is placed on the positive x-axis at = 3.98 . A third particle, of charge 6.05 is now placed at the point = 3.98 , = 3.01 . Part A Find the x-component of the total force exerted on the third charge by the other two. ANSWER: = 8.66×10−5 Correct Part B Find the y-component of the total force exerted on the third charge by the other two. ANSWER: = −5.40×10−5 Correct Part C Find the magnitude of the total force acting on the third charge. ANSWER: = 1.02×10−4 Correct Part D Find the direction of the total force acting on the third charge. ANSWER: = -0.557 Correct between and +x-axis Problem 21.68 Two identical spheres with mass are hung from silk threads of length , as shown in the figure . Each sphere has the same charge, so . The radius of each sphere is very small compared to the distance between the spheres, so they may be treated as point charges. Part A Suppose that the angle is small, and find the equilibrium separation between the spheres (Hint: If is small, then .)

Sex, Gender, and Popular Culture Spring 2015 Look through popular magazines, and see if you can find advertisements that objectify women in order to sell a product. Alternately, you may use an advertisement on television (but make sure to provide a link to the ad so I can see it!). Study these images then write a paper about objectification that deals with all or some of the following: • What effect(s), if any, do you think the objectification of women’s bodies has on our culture? • Jean Kilbourne states “turning a human being into a thing is almost always the first step toward justifying violence against that person.” What do you think she means by this? Do you agree with her reasoning? Why or why not? • Some people would argue that depicting a woman’s body as an object is a form of art. What is your opinion of this point of view? Explain your reasoning. • Why do you think that women are objectified more often than men are? • How does sexualization and objectification play out differently across racial lines? • Kilbourne explains that the consequences of being objectified are different – and more serious – for women than for men. Do you agree? How is the world different for women than it is for men? How do objectified images of women interact with those in our culture differently from the way images of men do? Why is it important to look at images in the context of the culture? • What is the difference between sexual objectification and sexual subjectification? (Ros Gill ) • How do ads construct violent white masculinity and how does that vision of masculinity hurt both men and women? Throughout your written analysis, be sure to make clear and specific reference to the images you selected, and please submit these images with your paper. Make sure you engage with and reference to at least 4 of the following authors: Kilbourne, Bordo, Hunter & Soto, Rose, Durham, Gill, Katz, Schuchardt, Ono and Buescher. Guidelines: Keep your content focused on structural, systemic, institutional factors rather than the individual: BE ANALYTICAL NOT ANECDOTAL. Avoid using the first person or including personal stories/reactions. You must make sure to actively engage with your readings: these essays need to be informed and framed by the theoretical material you have been reading this semester. Keep within the 4-6 page limit; use 12-point font, double spacing and 1-inch margins. Use formal writing conventions (introduction/thesis statement, body, conclusion) and correct grammar. Resources may be cited within the text of your paper, i.e. (Walters, 2013).

HST 102: Paper 7 Formal essay, due in class on the day of the debate No late papers will be accepted. Answer the following inquiry in a typed (and stapled) 2 page essay in the five-paragraph format. Present and describe three of your arguments that you will use to defend your position concerning eugenics. Each argument must be unique (don’t describe the same argument twice from a different angle). Each argument must include at least one quotation from the texts to support your position (a minimum of 3 total). You may discuss your positions and arguments with other people on your side (but not your opponents); however, each student must write their own essay in their own words. Do not copy sentences or paragraphs from another student’s paper, this is plagiarism and will result in a failing grade for the assignment. HST 102: Debate 4 Eugenics For or Against? Basics of the debate: The term ‘Eugenics’ was derived from two Greek words and literally means ‘good genes’. Eugenics is the social philosophy or practice of engineering society based on genes, or promoting the reproduction of good genes while reducing (or prohibiting) the reproduction of bad genes. Your group will argue either for or against the adoption of eugenic policies in your society. Key Terms: Eugenics – The study of or belief in the possibility of improving the qualities of the human species or a human population, especially by such means as discouraging reproduction by persons having genetic defects or presumed to have inheritable undesirable traits (negative eugenics) or encouraging reproduction by persons presumed to have inheritable desirable traits (positive eugenics). Darwinism – The Darwinian theory that species originate by descent, with variation, from parent forms, through the natural selection of those individuals best adapted for the reproductive success of their kind. Social Darwinism – A 19th-century theory, inspired by Darwinism, by which the social order is accounted as the product of natural selection of those persons best suited to existing living conditions. Mendelian Inheritance – Theory proposed by Gregor Johann Mendal in 1865 that became the first theory of genetic inheritance derived from experiments with peas. Birth Control – Any means to artificially prevent biological conception. Euthanasia – A policy of ending the life of an individual for their betterment (for example, because of excessive pain, brain dead, etc.) or society’s benefit. Genocide – A policy of murdering all members of a specific group of people who share a common characteristic. Deductive Logic – Deriving a specific conclusion based on a set of general definitions. Inductive Logic – Deriving a general conclusion based on a number of specific examples. Brief Historical Background: Eugenics was first proposed by Francis Galton in his 1883 work, Inquiries into Human Faculty and its Development. Galton was a cousin of Charles Darwin and an early supporter of Darwin’s theories of natural selection and evolution. Galton defined eugenics as the study of all agencies under human control which can improve or impair the racial quality of future generations. Galton’s work utilized a number of other scientific pursuits at the time including the study of heredity, genes, chromosomes, evolution, social Darwinism, zoology, birth control, sociology, psychology, chemistry, atomic theory and electrodynamics. The number of significant scientific advances was accelerating throughout the 19th century altering what science was and what its role in society could and should be. Galton’s work had a significant influence throughout all areas of society, from scientific communities to politics, culture and literature. A number of organizations were created to explore the science of eugenics and its possible applications to society. Ultimately, eugenics became a means by which to improve society through policies based on scientific study. Most of these policies related to reproductive practices within a society, specifically who could or should not reproduce. Throughout the late 1800s and early 1900s a number of policies were enacted at various levels throughout Europe and the United States aimed at controlling procreation. Some specific policies included compulsory sterilization laws (usually concerning criminals and the mentally ill) as well as banning interracial marriages to prevent ‘cross-racial’ breeding. In the United States a number of individuals and foundations supported the exploration of eugenics as a means to positively influence society, including: the Rockefeller Foundation, the Carnegie Institution, the Race Betterment Foundation of Battle Creek, MI, the Eugenics Record Office, the American Breeders Association, the Euthanasia Society of America; and individuals such as Charles Davenport, Madison Grant, Alexander Graham Bell, Irving Fisher, John D. Rockefeller, Margaret Sanger, Marie Stopes, David Starr Jordan, Vernon Kellogg, H. G. Wells (though he later changed sides) Winston Churchill, George Bernard Shaw, John Maynard Keynes, Supreme Court Justice Oliver Wendell Holmes and Presidents Woodrow Wilson, Herbert Hoover and Theodore Roosevelt. Some early critics of eugenics included: Dr. John Haycroft, Halliday Sutherland, Lancelot Hogben, Franz Boaz, Lester Ward, G. K. Chesterton, J. B. S. Haldane, and R. A. Fisher. In 1911 the Carnegie Institute recommended constructing gas chambers around the country to euthanize certain elements of the American population (primarily the poor and criminals) considered to be harmful to the future of society as a possible eugenic solution. President Woodrow Wilson signed the first Sterilization Act in US history. In the 1920s and 30s, 30 states passed various eugenics laws, some of which were overturned by the Supreme Court. Eugenics of various forms was a founding principle of the Progressive Party, strongly supported by the first progressive president Theodore Roosevelt, and would continue to play an important part in influencing progressive policies into at least the 1940s. Many American individuals and societies supported German research on eugenics that would eventually be used to develop and justify the policies utilized by the NAZI party against minority groups including Jews, Africans, gypsies and others that ultimately led to programs of genocide and the holocaust. Following WWII and worldwide exposure of the holocaust eugenics generally fell out of favor among the public, though various lesser forms of eugenics are still advocated for today by such individuals as Dottie Lamm, Geoffrey Miller, Justice Ruth Bader Ginsberg, John Glad and Richard Dawson. Eugenics still influences many modern debates including: capital punishment, over-population, global warming, medicine (disease control and genetic disorders), birth control, abortion, artificial insemination, evolution, social engineering, and education. Key Points to discuss during the debate: • Individual rights vs. collective rights • The pros and cons of genetically engineering society • The practicality of genetically engineering society • Methods used to determine ‘good traits’ and ‘bad traits’ • Who determines which people are ‘fit’ or ‘unfit’ for future society • The role of science in society • Methods used to derive scientific conclusions • Ability of scientists to determine the future hereditary conditions of individuals • The value/accuracy of scientific conclusions • The role of the government to implement eugenic policies • Some possible eugenic political policies or laws • The ways these policies may be used effectively or abused • The relationship between eugenics and individual rights • The role of ethics in science and eugenics Strategies: 1. Use this guide to help you (particularly the key points). 2. Read all of the texts. 3. If needed, read secondary analysis concerning eugenics. 4. Identify key quotations as you read each text. Perhaps make a list of them to print out and/or group quotes by topic or point. 5. Develop multiple arguments to defend your position. 6. Prioritize your arguments from most persuasive to least persuasive and from most evidence to least evidence. 7. Anticipate the arguments of your opponents and develop counter-arguments for them. 8. Anticipate counter-arguments to your own arguments and develop responses to them.
Assignment 2 Conditional Probability, Bayes Theorem, and Random Variables Conditional Probability and Bayes’ Theorem Problems 1-14 from Problem Set on Conditional Probability and Bayes’ Theorem I am including all the question here so that there is no confusion. Q1. Pair of six sided dices are rolled and the outcome is noted: What is the sample space? What is the size of the sample space? Suppose all we are interested in is the sum of the two outcomes. What is the probability that the sum of the two is 6? 7? 8? (Note: This can be solved using both enumeration and conditional probability method). Here, it makes more sense to use the enumeration approach than conditional probability. It is, however, listed here to set the stage for Q5. What is the probability that the sum of the two is above 5 and the two numbers are equal? Express this question in terms of events A, B, and set operators. What is the probability that the sum of the two is above 5 or the two numbers are equal? Express this question in terms of events A, B, and set operators. Q2. If P(A)=0.4, P(B)=0.5 and P(A∩B)=0.3 What is the value of (a) P(A|B) and (b) P(B|A) Q3. At a fair, a vendor has 25 helium balloons on strings: 10 balloons are yellow, 8 are red, and 7 are green. A balloon is selected at random and sold. Given that the balloon sold is yellow, what is the probability that the next balloon selected at random is also yellow? Q4. A bowl contains seven blue chips and three red chips. Two chips are to be drawn at random and without replacement. What is the probability that the fist chip is a red chip and the second a blue? Express this question in terms of events A, B, and set operators and use conditional probability. Q5. Three six sided dices are rolled and the outcome is noted: What is the size of the sample space? What is the probability that the sum of the three numbers is 6? 13? 18? Solve using conditional probability How does the concept of conditional probability help? Q6. A grade school boy has 5 blue and four white marbles in his left pocket and four blue and five white marbles in his right pocket. If he transfers one marble at random from his left pocket to his right pocket, what is the probability of his then drawing a blue marble from his right pocket? Q7. In a certain factory, machine I, II, and III are all producing springs of the same length. Of their production, machines I, II, and III produce 2%, 1%, and 3% defective springs respectively. Of the total production of springs in the factory, machine I produces 35%, machine II produces 25%, and machine III produces 40%. If one spring is selected at random from the total springs produced in a day, what is the probability that it is defective? Given that the selected spring is defective, what is the probability that it was produced on machine III? Q8. Bowl B1 contains 2 white chips, bowl B2 contains 2 red chips, bowl B3 contains 2 white and 2 red chips, and Bowl B4 contains 3 white chips and 1 red chip. The probabilities of selecting bowl B1, B2, B3, and B4 are 1/2, 1/4, 1/8, and 1/8 respectively. A bowl is selected using these probabilities, and a chip is then drawn at random. Find P(W), the probability of drawing a white chip P(B1|W): the probability that bowl B1 was selected, given that a white chip was drawn. Q9. A pap smear is a screening procedure used to detect cervical cancer. For women with this cancer, there are about 16% false negative. For women without cervical cancer, there are about 19% false positive. In the US, there are about 8 women in 100,000 who have this cancer. What is the probability that a woman who has been tested positive actually has cervical cancer? Q10. There is a new diagnostic test for a disease that occurs in about 0.05% of the population. The test is not perfect but will detect a person with the disease 99% of the time. It will, however, say that a person without the disease has the disease about 3% of the time. A person is selected at random from the population and the test indicates that this person has the disease. What are the conditional probabilities that The person has the disease The person does not have the disease Q11. Consider two urns: the first contains two white and seven black balls, and the second contains five white and six black balls. We flip a fair coin and then draw a ball from the first urn or the second urn depending on whether the outcome was a head or a tails. What is the conditional probability that the outcome of the toss was heads given that a white ball was selected? Q12. In answering a question on a multiple-choice test a student either knows the answer or guesses. Let p be the probability that she knows the answer. Assume that a student who guesses at the answer will be correct with probability 1/m where m is the number of multiple choice alternatives. What is the conditional probability that a student knew the answer given that she answered it correctly? Q13. A laboratory blood test is 95% effective in detecting a certain disease when it is, in fact, present. However, the test also yields a “false positive” result for 1% of the healthy persons tested (i.e., if a healthy person is tested, then, with probability 0.01, the test result will imply that he has the disease.). If 0.5% of the population actually have the disease, what is the probability a person has the disease given that his test results are positive? Q14. An urn contains b black balls and r red balls. One of the balls is drawn at random, but when it is put back in the urn, c additional balls of the same color are put in it with it. Now suppose that we draw another ball. What is the probability that the first ball drawn was black given that the second ball drawn was red? Random Variables Q15. Suppose an experiment consists of tossing two six sided fair dice and observing the outcomes. What is the sample space? Let Y denote the sum of the two numbers that appear on the dice. Define Y to be a random variable. What are the values that the random variable Y can take? What does it mean if we say Y=7? What does it mean if I say that Y<7? Q16. Suppose an experiment consists of picking a sample of size n from a population of size N. Assume that n≪N. Also, assume that the population contains D defective parts and N-D non defective parts, where n
