Answer 1

Answer #1

SOLUTION :

Distance of a star based on difference of apparent magnitude and absolute magnitude can be calculate by using the following formula :

Distance

= 10 ^[ ((apparent magnitude - absolute magnitude) + 5) / 5 ]

= 10^[ ((4.73 - 4.73) + 5) / 5 ]

= 10^[ 5 / 5]

= 10^1

= 10 parsecs : Option c. (ANSWER)

Hi! So this table on the picture has star information needed. the queastion is: “A star whose apparent magnitude and absolute magnitude are identical is licated at 10 persecs away from us (by definition). Star C is at 10 pc. Of the other four stars, rank them from closest, closer, farther, farthest.
