1. Let's say you calculateda synodic rotation period of28.09. What willthe sidereal rotation period of the sunbe? (Express your answer to two decimal places.)
2. Which of the following would be the best answer to "whatdo you get when you multiply 1700 mm/s by 1.575 m s?
3. The star Luthor is 310 pc from the sun. Luthor'sabsolute magnitude is -7. What is its apparent magnitude (toone significant figure)?
4. What would be the expected lifetime of a star with aluminosity of 160 solar units, and a mass of 4.3 solarmasses?
5. Let's say your best fit graph for a particular sunspothad a slope of 14.01.
What would be the synodic rotationperiod of the sun in this case?
6.
The star Barrett is 250 pc from the sun. Barrett'sabsolute magnitude is 4.5. Can Barrett be seen with theunaided eye? (Assume that even though this is in an alternateuniverse, that the naked eye limit is the same...)
No
