The apparent brightness of an object is calculated as: apparent brightness = (luminosity/4  distance2)
If one knew the luminosity and apparent brightness of a star that was too distant for a parallax measurement, what would be the best approach to determining its distance?
A) Insert the values for luminosity and apparent brightness into the equation, then guess the value for the distance that satisfy the equation.
B) Solve the equation for distance, then insert the values for luminosity and apparent brightness into the new equation.
C) The distance cannot be determined.
