Answer:
The place is located at a latitude of 49° to the North from the Equator.
Explanation:
The latitude is the first component of a astronomical location and is defined in a North-South orientation with respect to the Equator, whereas the second one corresponds with the longitude.
Since a place is located at 49° North and 163° West. Hence, the place is located at a latitude of 49° to the North from the Equator.
Answer:
At the same time, Dubrovnik became a cradle of Croatian literature. The entire city was almost destroyed when a devastating earthquake hit in 1667.
The statement is TRUE.
<span>The North Island of New Zealand is known for its volcanic activity, national parks and cosmopolitan cities.

Surrounded by bays and islands, it’s known as the “the City of Sails.” At its southern tips is harbourside capital Wellington, home to the national museum, Te Papa.</span>
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.
