1. What happens to shadows at sunrise and sunset? How are these shadows different from those cast at noon?
2. Study the information in the table below. What relationship do you see between a planet's speed of rotation and its length of day?
Diameter of planet Speed of Rotation Length of the Day
Planet A 3,000 miles 29 miles/second 24 hours
Planet B 2,990 miles 60 miles/second 14 hours
Planet C 3,020 miles 120 miles/second 8 hours
For number one, the shadows are longest at sunrise and sunset, and these are different from the ones cast at noon because they are longest and darkest. Hope this helped! I'll probably come back to help with the second one after I do more research :)
