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:
If the frequency of a wave increases while its speed remains constant, the wavelength decreases i.e. the distance between successive crests decreases.

Answer:
The Southern Hemisphere is dominated by oceans, relative to the Northern Hemisphere.
Explanation: The Southern Hemisphere is dominated by maritime influences, whereas the Northern Hemisphere is dominated by continentality.
The Southern Hemisphere has much less land than the Northern Hemisphere, resulting in weaker asymmetries at its lower boundary. A more zonally symmetric circulation, with smaller-amplitude stationary waves, is thus expected. Due to the larger fraction of the ocean, the seasonal cycle will also be muted. The seasonal change in surface temperature, for example, will be smaller than in the Northern Hemisphere.
Answer:
The Tropics receive more direct sunlight, resulting in warmer climates. The Poles receive almost no direct sunlight, resulting in a colder climate.
Explanation:
The tropics and the poles are two totally different regions on Earth. The differences can be seen in pretty much everything, from climate conditions to soil, geography, biosphere, precipitation, human activity, etc. One of the most noticeable and most important differences between the two is definitely the angle at which the sunlight falls.
The tropics are the region that receives sunlight at direct or close to direct angle all year round. This means highly concentrated sunlight and warm or hot weather conditions all year round. The poles are the region that receives sunlight at the lowest angle, having it constantly for around half a year, and then lacking it for half a year. This means very dispersed sunlight which can not warm up the surface and air, so the weather conditions are very cold all year round.
