Answer:
Rank of the stars from shortest to longest distances:
Barnard's Star (M4)
61 Cygnia A (K5)
Alpha Centauri A (G2)
Sirius (A1)
Spica (B1)
Explanation:
The habitable zone, also known as the circumstellar habitable zone, is the range of distances from a star where it is not too hot and not too cold for liquid water to exist on the surface of surrounding planets.
The location of a star’s habitable zone is dependent upon its luminosity, which is the amount of light emitted by an object in a unit of time, because a star’s luminosity increases with time; and also the star's mass.
The inverse square law of light brightness can be used to determine the extent of the habitable zones for different luminosity stars with the formula:
star boundary = Sun boundary × squareroot[(star luminosity)/(Sun luminosity].
Answer:
Whichever one is on the bottom in the oldest.
Explanation:
Over time, dust and dirt will cover older fossils.
Discoid-cleoid carver is useful for carving occlusal surfaces. Thus, option C is correct.
<h3>What are occlusal surfaces? </h3>
Occlusal surfaces are the term that is used to chew the food in this it is the top half of teeth that are used to chew or bite the food. And this part of the teeth is usually the part where one brushes the teeth.
