The answer is C because they show territory gained through the years
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.
C Italy and Greece have similar governments because blah blah blah I think so
<h2>Answer:</h2>
Balanced forces/Resultant force/ Newton's first law/law of inertia.
<h3>Explanation:</h3><h3>Balanced forces/Resultant force/ Newton's first law/law of inertia:</h3>
It says that each article will remain in its state of rest or similar motion in a straight line except a resultant force works on it. It is known as the law of inertia.
The inertia of the body is the hesitation of the target to alter its state of peace or movement.
The inertia of an article depends on its size. The greater the body, the greater the inertia. It shows it is difficult to start moving, stop, slow down, speed up or change direction. Force is required to overcome inertia.
B)wood,A renewable resource is a resource which is replaced naturally and can be used again. Examples are: oxygen, fresh water, solar energy, timber, and biomass. Renewable resources may also include goods commodities such as wood
