The population of the sub Sahara desert will grow in the years to come and has been growing for a while now. I know this because in the graph the line is climbing at the same crate constantly.
What exactly are you trying to figure out
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.
Answer:
Eastern is the correct answer (just look at a fking map)
Explanation:
Answer:
True.
Explanation:
In the ancient times the people usually lived in meadows, Plains and forests. There were very few or no crafted houses that we see in the modern world. The plains were used to produce agricultural goods. People use to breed their domestic animals near their homes. Their homes were usually built by wood which they use to scratch from trees.
