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.

Answer:
Brazil
Explanation:
Brazil has a developing mixed economy that is the twelfth largest in the world by nominal Gross Domestic Product (GDP) and eighth largest by purchasing power parity in 2020.
Brazil is rich in a variety of natural resources and is the world's leading producer of tin, iron ore and phosphate. It had large deposits of diamond, manganese, chromium, copper, bauxite and many other minerals.
Answer:
The sun, our star, will eventually die and become a white dwarf.
Explanation:
When a star dies it goes through a process in which it is called "The lifecycle of a star."
If the sun were to go theough this process and die out, it would eventually reach to the point it can either be a white or black dwarf, but there is more of a possibillity of it becoming a white dwarf than a black dwarf.
