Answer:
627.65 times
2.51^(10 - m) times
Yes, it makes sense
Step-by-step explanation:
Given that,
A magnitude 9 star is 2.51 times as bright as a magnitude 10 star
To find
<h3>a) </h3>
How many times as bright is a magnitude 3 star as a magnitude 10 star
10 - 3 = 7
2.51^7
627.65 times
<h3>b)</h3>
Expression to compare a magnitude m star to a magnitude 10 star
2.51^(10 - m) times
<h3>c)</h3>
Yes, it makes sense as a full moon is magnitude -13
so,
2.51^(10 - (-13))
2.51^(23)
1557742231 times
9:00 am to 1:00 pm is 4 hours.
The temperature dropped 2 degrees every hour so 2 x 4 = 8 total degrees.
Add 8 degrees to the final temperature to find the starting temperature.
-13 + 8 = -5 degrees at 9:00 am.
