Answer 2

On the changing HR diagram. This demonstrates the full power of the HR diagram, which allows astronomers to identify a star's internal makeup and stage of evolution by merely locating it on the diagram. Hence option D is correct .

What is Hertzsprung-Russell (H-R) diagram?

One of the most crucial tools for studying star evolution is the HR diagram, often known as the Hertzsprung-Russell diagram (HR diagram).

It was separately created by Ejnar Hertzsprung and Henry Norris Russell in the early 1900s and shows either the colour of stars (or spectral type) against their absolute magnitude or the temperature of stars against their brightness (the theoretical HR diagram) (the observational HR diagram, also known as a colour-magnitude diagram).

Every star goes through several developmental stages that are determined by its internal structure and method of energy production depending on its starting mass. any one of these phases corresponds to a change in the star's temperature and luminosity, and as the star develops, it may be observed moving to various locations on the HR diagram.

This demonstrates the full power of the HR diagram, which allows astronomers to identify a star's internal makeup and stage of evolution by merely locating it on the diagram.

California natives attempted to halt migrants’ entry into their state during the Dust Bowl era by taking all of the following actions except __________.

Answers

Answer:

burning land after harvest to communicate their resistance to migrant workers seeking entry into the state

Explanation:

During the dust bowl era, Californian territories were experiencing continuous sand storms. AS a result, the crops that were planted by the farmers were covered in sand and couldn't grow properly. This caused massive harvest failures for the majority of farms in California.

This was the reason why burning land after harvest was not a form of their resistance. The foods were really scarce at that time, they know better than making more damage to the farms regardless of their hatred toward migrant workers.

Darius I wanted to punish Athens for supporting a revolt that led to the start of the Persian Wars. The correct option is d.

Who is Darius l?

Darius I, commonly known as Darius the Great, was a Persian ruler who served as the third King of Kings of the Achaemenid Empire, reigning from 522 BCE until he died in 486 BCE. He ruled the empire at its territorial peak when it included much of Western Asia, parts of the Balkans and the Caucasus, most of the Black Sea's coastal regions, Central Asia, the Indus Valley in the far east, and portions of North Africa and Northeast Africa including Egypt, eastern Libya, and coastal Sudan.

Darius ascended the throne by overthrowing the legitimate Achaemenid monarch Bardiya, whom he later fabricated to be an imposter named Gaumata. The new king met with rebellions throughout his kingdom and quelled them each time. A major event in Darius' life was his expedition to subjugate Greece and punish Athens and Eretria for their participation in the Ionian Revolt.

Why Did Racial Violence Erupt in the 1920s?

Answers

Answer:

As black soldiers returned from Europe after World War One, and southern blacks migrated to northern cities by the thousands; as black writers and artists in Harlem spawned the New Negro movement, and black political spokesmen commanded national attention, "race" announced itself as a rapidly changing factor in postwar America. Racial pride advanced as a new "modern" generation of black leaders achieved self-directed gains in social and political realms. Racial hatred escalated to new extremes of virulence and destruction as whites resisted the inevitable adjustments to black advancement. The period saw the most horrific racial riots in U.S. history to that time, and also welcomed the first black representative elected to Congress since 1901. Here we explore the black-white division through commentary, political cartoons, visual art, and musical drama.

Which action causes breakers? Waves hit the shore at an angle and transport sand. Water flows away from the shore and moves sand with it. Underwater earthquakes cause motion throughout ocean water. Waves meet the shore and cause the crest to spill over the trough.

Answers

Option (d), Breakers are created when waves crash on the beach and the crest spills over the dip.

How are beach breakers created?

When a wave hits the shore, its base meets its bottom; the wave's front slows down and the rear overtakes the front. The effect is that the water is compelled to create a peak with a top that curves forward (crest). This peak will ultimately fall forward due to a breaker, a foam and water surge that is in a tumbling motion.

What causes waves to break?

The wave's base is slowed down by resistance from the ocean floor as the wave's top rushes ahead, causing the crest to begin to tilt more and more forward until it topples over and breaks on the coast.
