Answer:
equivalence
Explanation:
Recall that this principle is the basis of Albert Einstein's theory of general relativity. According to the German researcher, gravity is not a force that acts independently on each object, but rather a deformation of the same temporal space tissue.
According to the test carried out now by the team of astronomers, these three dead stars in two of their forms, a pulsar or a white dwarf, are perfect candidates to confirm the theory.
The equivalence was already understood centuries ago by Galileo Galilei. In his famous test of the spheres in the Tower of Pisa he demonstrated the existence on Earth. Subsequently, astronaut David Scott did the same on the lunar surface in 1971.
Now, this team has demonstrated it by studying two of the densest objects in the universe. Until today, many believed that the high density of the pulsar made him exempt from complying with the equivalence principle. However, being subjected to the gravitational field of one of the white dwarfs, the closest and least massive, after six years of observations, they have been able to demonstrate that both bodies have the same acceleration. And, if there is a difference, it is less than three parts between one million. That is the conclusion reached by a new test that tested Einstein and corroborated his theories once again.
<h2>The new
European imperialism of the late nineteenth and early twentieth centuries resulted in the carving up of most of the continents of Africa.</h2>
Explanation: This Imperialism gained its incentives from economic, military, political, generous, religious reasons and the growth of new technology.
To expand the markets of European mechanical business throughout the world by selling the products that lacked domestic market.
Businessmen and bankers wanted to invest their excess capital, and foreign investments offered the incentive of greater returns regardless of the risks. They experienced both positive and negative effects of imperialism.
The requirement of cheap labor and quick supply of raw materials was the reason to acquire these unexplored regions.

Answer:
B. Nation
Explanation:
B is the best answer here because culture, nationality, history, and ethnicity are all directly tied to one's country (nation). Territory and boundary are not as specific, and state is too narrow.
