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.
Cartography and meteorology
Answer:
The layers constitute fossils, calcium carbonate rocks
Explanation:
- Limestone is a biologic sedimentary rock and is formed by the collection of shells and debris. It can also be formed by the chemical process of sedimentary and precipitation of calcium carbonate.
- The limestone is composed of calcium carbonate, calcite, feldspar, and Quartz. Limestone represents karst topography and consists of the chemical composition of clay, iron, feldspar, and quartz. These are arranged in layers.
Answer:
Arithmetic Density
Explanation:
it is the total number of people divided by the total land area and this is just talking about population density not the amount of arable land (physiological density) or comparing the number of farmers to the area of arable land (agricultural density)
C is the answer, i know this is late but it can at least help some one else maybe
