Answer: Gravitational forces will be lower as separation distance increases. As two things become farther apart from one another, the gravitational connection among them weakens.
Answer:
Kelvin wave
Explanation:
The Kelvin waves are usually defined as one type of planetary waves that are characterized by the presence of large peaks as well as valleys that can eventually lead to the change in the depth of ocean water. These are non-break waves.
This type of wave occurs during the time of occurrence of El Nino, which flows only towards the eastern side covering the equatorial region. These are large waves extending up to thousands of miles.
This wave occurring in the equatorial region normally has two phases, namely the up-welling phase, and the down-welling phase, and this eventually leads to various changes in the surface temperature of the sea as well as in the subsurface region within the eastern part of tropical Pacific ocean.
Large groups of galaxy clusters that appear in sheetlike and threadlike shapes are known as superclusters. These are a cluster of galaxies which themselves occur as clusters as well. One example is the Virgo supercluster. It is a mass concentration of galaxies that contains the Virgo Cluster.
Answer:
A
Explanation:
The great contribution of Tycho Brahe was to observe planetary positions with sufficient accuracy so that Kepler could later use the data to discover the laws of planetary motion.
Tycho Brahe was a danish noblemen and an astronomer his major work was regarding the developing astronomical instrument to study the stars and pave the way for future discoveries.
what causes it is when the moon passes directly behind the Earth into its umbra. This only occurs when the sun, earth and moon are aligned exactly or closely
