Answer: is constant
Explanation:
In order to analyze the velocity of the stars within a galaxy, the <u>galaxy rotation curves</u> (developed by the American astronomer Vera Rubin) are used. These graphs are elaborated as a scatter diagram in which the orbital velocity of the stars present in a galaxy is represented on the Y axis and the distance of these stars to the center of the galaxy on the X axis.
Thanks to this diagram, it has been possible to observe a characteristic behavior in the rotation speed of the stars (and gas) present in the galaxies, which differs from the rules of the orbital movement of the planetary systems postulated by Newton and Kepler.
This means that in these galaxy rotation curves it has been observed that the rotation speed of stars and gas is "constant", regardless of the distance to the center of the galaxy. This discrepancy and these results were then used to demonstrate the existence of dark matter in the universe.
F the instructor gives you 5 functions of the liver during a lecture, go out and try to find information about more functions (that the instructor didn't mention or perhaps doesn't know). In the end, you may add two more functions of the liver and in the process remember all of them better.
Answer:
The statement that explains the best the reason why space exploration should continue in the future is:
b. Space exploration prevents the occurrence of severe weather conditions on Earth.
Explanation:
The reason behind this is that thanks to the exploration of space we have discovered how the sun irradiates and when it increases its irradiation. Also, when electromagnetic forces from space can follow its course on the space and affect negatively our ecosystem. But moreover, because we can compare what can happen to our planet when different events start to happen, as the weakening of the atmosphere.
