The picture below shows the photos taken by the photographer at night with continuous exposure technology. The arc in the photo is the apparent trajectory of the star. Look at the picture and complete the small question. small

Question 1:A

Question 2:B

Question 1: The elevation of Polaris observed in the northern hemisphere is consistent with the local latitude. According to the low viewing angle of Polaris in the picture, it can be inferred that the photographer's shooting location is in the low latitude area of the northern hemisphere.

Question 2: With a distant star as the reference, it takes about 24 hours for the earth to rotate 360 once a week, that is, 15/ 1 hour. The apparent motion of star A turned about 50, and the shooting time was more than 3 hours.
