1. Assuming the solar day is 24 hours, how long does it take for the disk of the sun to move its own width (1/2 degree) across the sky on about March 21, as seen from earth's equator?
2. If you are 6 feet tall and standing at 45 degrees latitude, what is the length of your shadow on March 21 at midday? (Assume flat, level ground.)
3. If a star is seen to rise at 9 pm on July. 10, on what date will it rise at 8 pm?
Any assistance with these would be greatly appreciated!!
