Note: All calculations must show your stepbystep work to receive credit. Preparatory Work: Assigned readings and homework problems The questions below are related to an asteroid in orbit around the Sun. 1. As mentioned in an earlier of this project, occasionally an asteroid fragment makes its way to Earth. As the fragment falls through the atmosphere, it is heated and some of the material is vaporized. a. (10 points) Explain how you could determine the composition of this hot vaporized material from the light it emits. b. (5 points) Provide an example of how this type analysis is used during the testing of soil, water, oil, or air samples. Provide a reference to the source of your information and reasons why it should be considered a reliable source. (Note: this Checklist to Evaluating Web Sites may be helpful in evaluating your source of information.) 2. Some asteroid fragments end up on the surface of Earth. Such fragments could be radioactive. a. (4 points) What is the chief cause of radioactivity? b. (4 points} List and describe the three different types of radioactivity. c. (7 points) Suppose that you had a radiation detector that could not the identify the type of radiation being emitted from a fragment sample. What else could you use, in conjunction with the detector, to determine the type of radiation being emitted? Explain. 3. (10 points) In your own words, explain how the age of this fragment could be determined. Be detailed in your explanation and provide references to any sources of information you may have used. Additionally, explain why any sources used should be considered reliable. 4. Asteroids are mainly composed of metals like iron and nonmetals like carbon. a. (10 points) Explain at least three differences between metals and nonmetals. Specifically use iron and carbon in your explanation. b. (5 points) Describe the locations of metals and nonmetals within the periodic table
