Answer:
<em>Developing countries two major issues, of low incomes and eventually lower tax collections.</em>
Explanation:
Obstacle 1: Developing countries usually have a population with a low income. There are a lot of poor people, very few businesses are documented and there are very few well established larger corporations.
Obstacle 2: Lower income results in a low tax collection for the country. This means that the government is not able to meet its basic infrastructure resulting in underdeveloped health facilities and basic infrastructure.
In order to improve this, they look for either foreign direct investment into their country or take out loans from international banks to fund basic needs.
If done well, countries can escape from poverty. However if loans are mismanaged, countries can quickly find themselves burdened with rising debt and more poverty.

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.
