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:
This is an image of a normal spiral galaxy.
Explanation:
The normal spirals have arms that emanate from the nucleus.

Answer:
How do vertical gardens adapt to climate change?
Key benefits of green infrastructure include direct alleviation of urban heat island effect through shading of heat-absorbing surfaces and via plant evapotranspiration; reduction of maximum temperatures in the vicinity by shading walls from the sun; reduced heat entry into buildings through the absorption or reflection
Explanation:
Answer:
lowest level of the atmosphere
Explanation:
The reason why its found in the lowest lvl is mainly because 99% of the water vapor in the atmosphere is found in the troposphere(lowest level)
