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:
d.
Explanation:
Nuclear energy can create a safer environment for humans.
It can produce electricity.
It releases less radioactivity into the atmosphere than burning coal.
However I found nothing on if it reduces the use of fossil fuels, but in the future it could replace them alongside possibly renewable energy, so take the answer piece of cake.
Answer:
X is located at 640ft in elevation.
The western side is steeper because the lines are closer together than the other sides of the hill.
Explanation:
Each contour line represents a 20ft increase in elevation. You can see the 600ft line labeled on the map, so the next one in is 620, and the one labeled "X" is 640.
Contour lines that are farther apart indicate a more gentle slope that is increasing its height over a longer distance. Just like a graph in math class, slope is "rise over run," so a flatter slope tells us that the height is increasing slowly. Close contour lines show us that the height is going up very quickly.
