Absolute magnitude _____. represents how bright a star looks from Earth describes a star's brightness in comparison to the sun measures only luminosity measures both luminosity and distance

Answers

Answer 1

Absolute magnitude measures only a star's luminosity.

It's a number that tells how bright a star would look if ALL stars were the same distance from Earth.

Answer 2

Absolute magnitude is how bright the star appears at a standard distance of 32.6 light-years.

The absolute magnitude measure of a celestial body's intrinsic brightness is represented as the apparent magnitude the object might have if seen from a distance of 10 parsecs.

How to find absolute magnitude?
Mv = m - 2.5 log[ (d/10)2 ]. Stars farther than 10 pc have Mv more negative than m, that is why there is a minus sign in the formula. If you use this formula, make sure you put the star's distance d in parsecs (1 pc = 3.26 ly = 206265 AU).

13. The continued rise of the Himalayan mountain range is due to

A. plate convergence.

B. isostatic uplift only.

C. isostatic uplift fault block formation.

D. isostatic uplift and plate convergence.

Answers

Final answer:

The increasing height of the Himalayan mountain range is due to plate convergence, caused by the collision of the Indian and Eurasian tectonic plates. Though isostatic uplift does contribute to this rise, it is not the sole cause.

Explanation:

The continued rise of the Himalayan mountain range is due to plate convergence, so option (A) is correct. The Himalayas are formed by the collision of the Indian and Eurasian tectonic plates. This collision causes the crust to thicken and uplift, resulting in the formation and rise of the mountains. The process of isostatic uplift does play a part in this, although it is not the sole reason for the rise of the range. Isostatic uplift isn't a fault block formation, hence options B, C, and D aren't accurate.

Read this paragraph from The Dark Game.It may seem surprising that no Confederate sympathizers took action against Van Lew, given her strong and public views on secession and slavery. Surely there were suspicions, especially among her upper-crust neighbors, but the matter never went beyond those suspicions. Historians have suggested that the secessionists were victims of their own cultural bias, believing that no aristocratic person, and certainly not a lady, would ever consider taking part in anything as impolite as spying. A true lady managed her servants, prepared parties and gatherings, and blindly supported her husband. Such attitudes worked in Van Lew's favor, diverting suspicion from her.What central idea is implied in this paragraph?1. Elizabeth Van Lew did not follow the rules society set forth for ladies of her time and social class.2. Elizabeth Van Lew was a successful spy because society did not expect a lady to serve in that role.3. Elizabeth Van Lew was able to disguise her spying activities because she kept her views about the war to herself.4.
