Using a straightedge for the lines you need to draw, make a two-dimensional diagram of a lunar eclipse that shows why there is an umbra and penumbra. Using dark and light shading with your pencil, clearly indicate the penumbra and umbra. Because you probably do not have a compass in your pocket, we have provided images of the Sun and the Earth in Figure 2. Your diagram should show the Moon in a position where the eclipse is still partial. Earth Sun B. If you draw the diagram correctly, from any point in the umbra you should not be able to draw a line back to any part of the Sun that does not first intersect the Earth; therefore, no light from the Sun can reach the Moon. Draw an example line. This indicates that the umbra is total shade. FIGURE 2. Sun and Earth during a lunar edlipse C. From any point in the penumbra, some, but not all, lines can reach the Sun without intersecting the Earth. Draw a solid line toward the Sun from the penumbra that intersects the Earth and draw a dashed line from the penumbra that goes althe way to the Sun. This indicates that the penumbra is not total shade

Explanation / Answer

we know that earth rotates 360 degrees in 1440 min
Thus it rotates 1 degree in 1440/360 = 4 min
thus to rotate 12 degrees it takes 4*12 = 48 min
Therefore it would take 48 min to rotate the earth 12 degrees.
48 min later the moon set or rise.

If it rises at 10 pm then tomorow it will rise at 10:48 pm.

No the moon would not be on the piscer edge tomorrow night because it would move 12 degrees East

This has happened because the moon has moved farther east. The moon moved the greatest angle. .
