Knowing that the diameter of the Earth at the equator is 12 740 km, compute the radial acceleration of a point on the surface of the Earth at the equator, due to the rotation of the Earth about its axis.
The Radial Acceleration Problem is a phenomenon in physics where the observed acceleration of stars and galaxies in the outer regions of a galaxy is greater than could be explained by the visible matter within that galaxy. This led to the hypothesis of the existence of dark matter, which has yet to be directly observed.
The Radial Acceleration Problem is measured by observing the rotation curves of galaxies, which show the velocity of stars and gas at different distances from the center of the galaxy. By comparing these curves to the expected velocity based on the visible mass of the galaxy, scientists can determine the presence and amount of dark matter.
Some proposed explanations for the Radial Acceleration Problem include the existence of dark matter, modifications to the laws of gravity, and the possibility of a large number of small, dim stars that cannot be detected by current technology.
While the presence of dark matter and the Radial Acceleration Problem are widely accepted in the scientific community, there is ongoing debate and research on the exact nature of dark matter and its role in explaining the phenomenon. Therefore, it can be considered a well-established concept, but one that is still being actively studied.
The Radial Acceleration Problem is an important puzzle in our understanding of the universe, as it challenges our current understanding of the laws of physics and the composition of the universe. By studying this phenomenon, scientists hope to gain a deeper understanding of the fundamental forces and components that make up our universe.
