Question

1. read the equation below.

$m - m = 5\log(\frac{d}{10})$

which of the following variables represents the absolute magnitude of the star?

$\bigcirc$ log

$\bigcirc$ (m)

$\bigcirc$ (m)

$\bigcirc$ (d)

Explanation:

In astronomy, the formula \(m - M=5\log(\frac{d}{10})\) is used. Here, \(m\) represents the apparent magnitude (how bright a star appears from Earth), \(d\) represents the distance of the star from Earth, and \(M\) represents the absolute magnitude (how bright a star would appear if it were at a standard distance of 10 parsecs from Earth). The \(\log\) is a mathematical operation (logarithm).

Answer:

\((M)\)
