four stars of equal size emit the same amount of energy. the distance of these stars from earth is shown in the following table.

distance from earth star distance from earth (light years)

p 2.3

q 7.8

r 6.5

s 3.2

what is the order of apparent magnitude of the stars, starting from the least to the greatest? q, r, s, p

p, s, r, q

r, s, p, q

q, p, s, r

Q, R, S, P is the order of apparent magnitude of the stars, starting from the least to the greatest.

Q, R, S, P

Explanation:

The apparent magnitudes of the star is the brightness calculated by an observer at a particular distance from the Earth. The smaller the distance between the star and the Earth, the greater the apparent brightness.

So , from the given distance (in light years), Q,R,S,P is the answer (least to the greatest apparent magnitude) (distance is greatest to least).

im doing test rn im going with 2 but ill give answer if itss wrong,   : )
