10) Consider the student comment below. Student: The amount of time that all stars are above the horizon is 12 hours because it takes 12 hours for a star to rise in the east and then set in the west. Do you agree or disagree with the student? Explain your reasoning.

Part II: Looking East.
Figure 3 shows an extended view along the eastern horizon showing the positions of Stars A
and B at 6 pm. The arrow shown is provided to indicate the direction the Star B will be
moving at 6 pm.

7) Recall that in Question 6, you found that Star A ends up high in the southern sky when it
is halfway between rising and setting (and therefore never passes through the zenith).
Draw a straight arrow at the x in the east in figure 3 (the position of Star A at 6 pm) to
indicate the direction Star A moves as it rises. Studying Figure 2 can also help clarify
your answer.
8) Two students are discussing the direction of motion of a star rising directly in the east.
Student 1: Stars move east to west so any star rising directly to the east must be moving
straight up so that it can end up in the west. If the arrow were angled the star would not
set in the west.
Student 2: I disagree. From Figure 2, the path of Star A starts in the east, then it moves
high in the southern sky yet still sets in the west. To do this it has to move toward the
south as it rises so I drew my arrow up and to the right.
Do you agree or disagree with either or both of the students? Explain your reasoning.

9) Imagine you could see Star B at noon. Fifteen minutes later, in what direction will Star
B have moved? Explain you reasoning.
10) Consider the student comment below.
Student: The amount of time that all stars are above the horizon is 12 hours because it takes 12
hours for a star to rise in the east and then set in the west.
