You receive 8 x 10-9 W/m² of energy from a star that is 2 parsecs away, it has a V-band apparent magnitude my = -1.5. How much more/less flux do you receive from a star with an apparent magnitude my = 5.3? For the first star, what is its V-band absolute magnitude?

Question

How does one go about these questions?

1. You receive 8 x 10-9 W/m² of energy from a star that is 2 parsecs away, it has a V-band apparent
magnitude my = -1.5. How much more/less flux do you receive from a star with an apparent magnitude
my = 5.3? For the first star, what is its V-band absolute magnitude?
2. Consider two identical stars, A and B. Star B is 10 times farther away than star A. What is the difference
in magnitudes between the two stars?
