Question

Sean enjoys studying the stars. He used a photometry tool to calculate several stars' apparent magnitudes (how bright a star looks in the sky). He then researched the stars' distances from Earth. He recorded his results in the table below.

Answer 1

Star
Apparent
Magnitude
Distance from
Earth
Sirius A
-1.47
8.6 light-years
Alpha Centauri A
-0.01
4.4 light-years
Rigel
0.12
770 light-years
Procyon
0.34
11 light-years
Alpha Centauri B
1.33
4.4 light-years

What conclusions can Sean draw from his chart?
A star's apparent magnitude decreases as its distance from Earth increases.
A star's apparent magnitude is not directly related to its distance from Earth.
A star's apparent magnitude decreases if it is very close to another star.
A star's apparent magnitude increases as its distance from Earth increases.

Answer 2

please need help

Answer 3

It seems like the star's AM gets smaller as the distance fro Earth increases
