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.

Explanation:
If Toronto, Ontario, Canada was affected by climate change, most likely the climate here would get much warmer. People might decide to move out of Toronto because it would get uncomfortably warm, and people choose to live there for it's cold climate.

Answer:
Nini to the rescue again! Plz <u>mark brainliest</u>! I'll include the same answer if you didn't see mine the first time.
Explanation:
1) The peninsular plateau, under influence of the sea from three sides, has moderate temperatures.
2) The effect of monsoon on the Indian subcontinent is quite perceptible. The seasonal alteration of the wind systems and the associated weather conditions provide a rhythmic cycle of seasons.
3) The people of India especially the farmer from north to south and from east to west, eagerly await the arrival of the monsoon. These monsoon winds bind the whole country by providing water to set agricultural activities in motion. The river valleys which carry this water also unite as a single river valley unit.
