11. Imagine that the solar system formed with the temperatures as indicated by the graph below. The graph shows that the distance from the center of the protoplanetary disk on the x-axis, and the temperature on the y-axis. The horizontal dashed line marked “water” indicates the temperature at which water would condense. If the solar system had formed with the temperatures indicated at these distances what would the planets be made of and why? ANSWER: Outer Planets are Terrestrial and the Inner Planets are Jovian. This is because the temperature is lower at the center of the protoplanetary disk in this scenario and in this case OUTSIDE the frost line actually means that it gets hotter the farther away, and so water would melt outside this water line and the outer planets would be Jovian.

...Review List (Exam 2) 10/27/2010 This review list covers important topics for Exam 2 (Annuities, Health Insurance, Chapter 19 to 24, and Special Topic 2). This list should be used only as a reference for exam preparation. All materials that are covered in the lectures and in the related sections of the textbook are testable unless explicitly excluded. Annuities (Chapter 14) 1. What is “annuity”? Why do we need it? An annuity provides periodic payments to an annuitant, which continue for either a fixed period or for the duration of a designated life or lives. The fundamental purpose of a life annuity is to provide lifetime income that cannot be outlived. 2. Understand how annuities work. 3. What are common types of annuities? Understand how fixed annuity and variable annuity work and their differences. Fixed annuity pays periodic income payments that are guaranteed and fixed in amount. It can be purchased so that the income payments start immediately, or the payments can be deferred to some later date. Deferred annuities typically provide for flexible premiums. Variable annuity pays a lifetime income, but the income payments vary depending on investment experience of the subaccount in which the premiums are invested. The purpose of this type of annuity is to provide an inflation hedge by maintaining the purchasing power of the periodic payments. Equity indexed annuity offers the guarantees of a fixed annuity and limited participation in stock market gains. ......

The Sociological approach: a. is not scientific b. suggests that relations we have with other people create opportunities for us to think and act c. suggests that relations we have with other people set limits on our thoughts and actions d. leaves the study of personal issues to psychologists e. b and c * EXPLANATION: Although sociology contains both objective and subjective elements it is a science. Sociologists observe reality in a systematic and controlled manner and evaluate the validity of their ideas based on observations. Objectivity plays the role of a reality check while subjectivity makes us set our priorities for research. The sociological approach to improving human welfare is based on the idea that the relations we have with other people create opportunities for us to think and act but also set limits on our thoughts and actions. Accordingly, we can better understand that what we are and what we can become by studying the social relations that help shape us. FOR EXAMPLE: even the most personal issues can be studied using a sociological approach Suicide could have been seen as an anti-social act caused by psychological distress but Durkheim studied it from a sociological perspective correlating it to “social solidarity”, how frequently people interact with others and share their beliefs, values and morals. Social forces then determine the likelihood to commit suicide. Sociologists use...
