Describe the approximate direction, in horizon coordinates (i.e. altitude and azimuth), of the sunrise (if any) from the following locations on the given dates. Tell a bit about why this event might be unusual (if at all). Also estimate how long it takes for the Sun to clear the horizon (the Sun has an angular diameter of about 0.5 degrees).
NOTE: as originally posted, the question below makes no sense. Please
don't worry about answering it. If you've already handed in your homework,
rest assured that this won't be counted - but if you could think of a reason
why astronomers woudl be happy that is different than why most other people
would be happy, that is great!.
And why might astronomers near the North Pole also be happy on that same day?
What is the altitude of the noon Sun on the following dates at these locations?
Explain why the synodic month is longer than the siderial month. You will need to explain the meaning of the two months in your answer. Show, simply (i.e. with one line of math or clear words) why the difference is 2 days.
It is an unwritten rule in baseball that the orientation of the diamond points northeast - that is, the line starting at home plate, running in the direction of second base, usually points to an azimuth of about 45 degrees. Speculate on why that might be, given the usual position of the batter and fielders and the direction of their gazes. Remember that baseball traditions mostly originated before stadium lights were invented; i.e. think of day games.
