question5 astronomy lso, the solutions will be shown on our Gauchospace very soon after the due date. Partly for is reason, we cannot accept late homework! (Only exception: if you have an emergency and l me before the due date). stly, we will have to pick one or two to correct carefully and assign 10 points to each. For the hers, the TA will just check that a reasonable effort has been made, and if so, they will give 5 ints for each 1, Chapter 2 #5, 6, 7, 8 2, Chapter 2#9, 10, 11, 12 3, Chapter 2#13, 14, 15, 16 4, Chapter 2 #20, 24, 40 5. About how far (in angular units) does the Sun move on the celestial sphere (i.e. relative to the stars) in one day? How about for the moon? As on all HW problems, your score will be based on the reasoning and calculations you show, so don't just give the answers. a) JBS Haldane, a great biologist of the 20th century, said something variously quoted like, "The universe is not only stranger than we imagine, it's stranger than we CAN imagine." What do you think he meant by that? b) Einstein once said, "The most incomprehensible thing about the Universe is that it is comprehensible." What do you think he meant by that? 6.Explanation / Answer
Q5.
a) it takes exactly 1 year for the sun to make a complete trip around that circle.
So that means it takes the sun 365 days to go 360 degrees around the circle of constellations.it's 360/365 = 0.986 degrees per day.
b) The moon appears to move completely around the celestial sphere once in about 27.3 days as observed from the Earth.Since the Moon must move Eastward among the constellations enough to go completely around the sky (360 degrees) in 27.3 days, it must move Eastward by 360/27.3 = 13.19 degrees each day.
