The <u>apparent magnitude</u> of a star refers to its brightness as seen from your eyes and <u>absolute magnitude</u> being the actual brightness of a star.
<h3>What is magnitude?</h3>
Magnitude can be defined as a unitless measure which is used to show the brightness of an object in comparison with the brightness of another object.
Basically, there are two types of magnitude and these include the following:
In conclusion, the <u>apparent magnitude</u> of a star refers to its brightness as seen from your eyes and <u>absolute magnitude</u> being the actual brightness of a star.

Answer:
All object changes are compared with a <em>reference</em> , which is an object that appears to stay in place.
Explanation:
In scientific experiments, the changes in the experimental object are observed by comparing the changes with a reference object. In the reference object, no changes are made and conditions are kept normal in it. For example, if we want to measure the distance of two cars from a point, the point will be the reference point from which the distance shall be measured. Hence, all changes are made by comparison from a reference object or point.
Answer:
330 m/s
Explanation:
The sound wave has to travel TO the cliff AND back = 2 * 49.5 = 99 m
magnitude of velocity = distance / time = 99m / .3 s = 330 m/s
Answer:
carbon is that component :)
