Question

Recall that one hour of right ascension is equal to 15 degrees. One minute of right ascension is equal to 0.25 degrees. During a full moon, the sun and the moon are 180 degrees apart from one another in the sky. How many hours of right ascension separate the sun and moon during a full moon?a) 180 hoursb) 24 hoursc) 12 hoursd) 165 hourse) 6 hoursf) 2 hoursg) 15 hours

Answer 1

The right answer is option C

Step-by-step explanation:

An hour of right ascension is 15 degrees

A minute of right ascension is 15 degrees / 60 minutes = 0.25

For a full moon where the sun and moon are 180 degrees apart. We calculate by finding the number of hours in 180 degrees. Recall there 15 degrees in an hour.

180 degrees / 15 degrees = 12 hours
