C. Distance from Earth
The observed brightness of a star (the apparent magnitude) to an absolute magnitude, you need to know the distance [d], to the star. Alternatively, if we know the distance and the apparent magnitude [m] of a star, we can calculate its absolute magnitude [d].
*paraphrased from "COSMOS.com"
MA= output force/input force
MA= 100N/20N
MA= 50
Answer:
just see it it will help trust me its my school work
Explanation:
We know that there are 100 cm in 1 m, so we can use this to convert to meters:

Therefore we know that
cm is equal to 2.41 m.
