1. Did you ?nd that a large portion of the program galaxy's mass was dark matter?
2. What was the fraction of baryonic matter in the program galaxy?
3. What was the fraction of dark matter in the program galaxy?
4. Suppose the program galaxy were more luminous. This would cause the percentage of dark matter to 6
5. Ifthe mass-to-light ratio were larger, then the percentage of dark matter would ' be ,
6. Ifa galaxy were viewed face-on instead of edge-on, then would you be able to measure the rotational velocity? Why?
7. If a different galaxy's rotational velocity curve showed Keplerian motion, then what would this indicate.
8. What is the rotational velocity of the program galaxy at radius -10 kpc?
9. What is the gravitational mass within a radius of -10 kpc for the program galaxy? '
10. How do you think the amount of dark matter in our Milky Way Galaxy compares to the amount of dark matter-in the program galaxy?
