Astronomy 101 Final Exam (150 pts.)Final exam is Friday, May 16 at 8:00 am - 10:00 am physics lecture hall (1412). Bring # 2 pencil, a pen, and your student ID.The final is cumulative, however, the new material from Apr.29—May 13 will receive greater emphasis (at least 70% short answer questions). There will be 50 multiple choice questions worth2 pts. each (total of 100 pts.) and 5 multipart short answer questions worth 50 pts. The final exam totals 150 pts.New MaterialLecture & Book: - Extraterrestrial life (4/29), which was followed up, by a group discussion anda homework problem. Follow the syllabus for remaining topics and material in book. (Reading on ET Life is listed on syllabus under Apr. 22)Discussion: You did a group activity and will be given a blue summary sheet--on Extraterrestrial life and The Drake Equation. You do not need to memorize the Drake equation but you should befamiliar with the terms and what goes in to selecting values for the most important terms. There will be solutions for HW #5 available on May 8.Lab: Since last exam, Labs 11, 13, The Hubble Redshift Distance Relation.Lecture: There was a handout (white) on ET Life. There will be a running paper on the expanding universe.STUDY your lecture notes for entire semester, Skywatch, and Milkyway summaries, terms and questions. Review your homework and solutions, all labs, previous exams (2—3multiple choice questions from each exam will appear, and also questions that re-test what was asked in short answer sections), quizzes, lecture & discussion activities. Use the STAR CENTER exams to help you prepare for the final.New material and things you should be able to explain/describe:Review accretion disk models for both supermassive and regular black holes. Extraterrestrial Life, Drake Equation—see blue summary sheetMilkyway galaxywhat we see; what we don't see visually, Dust problems--Herschels’ modelRadio and infrared observations, esp. How is 21 cm radiation produced?--sketchGlobular clusters, overall structure--Shapley’s modelGalaxies beyond Milkyway--how are distances determined?Hubble's investigation of Andromeda, using Cepheid variables (Period/Luminosity relation)Hubble's classification of galaxies: types and characteristicsHubble's Law/Diagram, how do astronomers use Hubble’s law?Expansion of the UniverseWhere does this idea come from? What does it really mean? What doesn’t it mean?Dark Matter--where does this theory come from? Large scale structure--How do we “map” the universe? Bubbles and near VoidsGalactic Evolution--Galactic collisions, mergers and cannibals; observations & explanationsQuasars and active galaxiesObservations & Models to explain, Looking back in time concept--what does it mean?Big Bang TheoryCosmic background radiation--where does it come from? what does it tell us about the early universe?Future of the Universe--2 possibilities hereGeneral overview questions: Where are we in terms of space and time?Where? Planet Earth--Solar System, galaxy, universeAge? How old is the Earth? --Solar System, galaxy, universeAppreciation/understanding of sizes, masses, ages, distances in astronomyPutting it all together questions--Life perspectives (here and elsewhere)Makeup Lab for those with excused absences (Labs 11-14) is scheduled for the Study Day, Thursday, May 15 from 8:30-10:30 AM. You must sign up in lab this week with your TAs approval.REVIEW SESSION: Thursday, May 15 11:00 AM -12:15 PM in physics 1412. Thursday, May 15 9:00 PM – 10:00 PM in CSS 2400 before eclipse!Bring your questions!Mrs. Deming's office hrs. (CSS 1233)Monday May 12 9:00 AM – 11:00 AMTuesday May 13 12:30 - 2:30 PMGood Luck studying for the final.I hope that you look back on ASTR 101 fondly.I had fun teaching your class this semester & hope you have enjoyed learning about astronomy!Mrs. DemingASTR 101 COSMOLOGY REVIEW1. Given the following HR Diagrams for star clusters choose the one that you would expect to come from the oldest cluster.Now explain your answer:2. Given the Hubble Diagram below, estimate the distance to a galaxy whose velocity of recessionis 40,000 km/sec.3. Astronomers use a supermassive blackhole model to account for the observations made of quasars. Sketch this model and label the important parts. Describe below your drawing how X rays are produced and why a jet might be observed.On the back of this page, sketch the appearance of our Milky Way Galaxy. Where would you find a globular cluster; an open star cluster; a cool, cloud of hydrogen; a hot, young O main sequence star; and the Sun. Explain why it has only been possible to make such maps since the 1950s.Figures 15-2a, , 15-3, 15-6, 15-7, 15-8,15-12, 15-16, 15-17, pp. 358-359, Table 15-1.pp. 376-377, Fig. 16-3, 16-8, 16-9, 16-10, 16-11, 16-12, 16-13, 16-14.p. 394, 398-399, Fig. 17-3, 17-4, 17-5, 17-7, 17-8, 17-10.pp. 418-419, Fig. 18-4,18-6, 18-10, 18-13, 18-15, 18-16, Table
