9 Quantitative Questions (0 points each) The comet Hale-Bopp has an aphelion distance of 371 AU and a perihelion distance of 1 AU; therefore, Hale-Bopp s average distance from the sun is 186 AU. Using Kepler s third law, find the orbital period of Hale-Bopp? p a p a 3 3/ 186 3/ yrs Using Newton s version of Kepler s third law and the orbital period and average distance of Hale-Bopp, calculate the mass of the Sun. (Hint: be careful with units: m, kg, sec) a = 186 AU = 186 AU * 1.5*10 11 m/au =.79*10 13 m p = years = 8*10 10 sec p 4 G( M M Sun HB a ) 3 M Sun +M HB M Sun M Sun 3 4 a 4 ( Gp ( m kg s 3 m) )( s) m m kg M Sun

10 Short Answer Questions (0 points each) Describe the two most important properties of a telescope. Explain what they mean and why they are important. The most important property of a telescope is its collecting area or the size of its objective lens. The only information we get in astronomy comes from light, so the more light we can collect the better, and a bigger lens allows us to collect more light. The second most important property is its angular resolution. The angular resolution is the smallest angular separation that two point-like objects can have and still be seen as distinct objects rather than one smeared-together-looking object. Smaller is better. Please explain how the greenhouse effect works. Use words and a diagram. The sun emits visible light, which has no trouble passing right through the greenhouse gasses in the atmosphere. The visible light reaches the ground, providing energy and heating it up. Everything with thermal energy emits light, so the ground, which is heated to about 300K, emits IR light. The greenhouse gasses trap the IR light in the atmosphere. The atmosphere then reradiates that light, much of which comes back to the surface, heating it a little further. The constant incoming visible light and the trapped IR light combine to continually heat the surface.
