The sun. But at the center of our galaxy (Milky Way) is a supermassive black hole called Sagittarius A- star
The correct answers are:
- Polar ice caps would melt, increasing sea levels;
Because of the rise of the temperatures, the permafrost, glaciers, and polar ice caps would mostly melt. As they melt, they will increase the sea levels significantly because they will introduce much more water into the the seas and oceans.
- Wildlife would have to migrate or die;
With increasing sea levels, as well as change of habitats, lot of animals would find themselves in situation where they will have to migrate, because if they don't, they will find themselves in water and drown, or starve to death.
- Hurricanes and typhoons could increase in intensity;
Because the water in the sea levels will increase, and the water bodies will become even bigger, the hurricanes and typhoons will be able to become stronger and more intense, thus be more destructive as well.
Answer:
The true statement is that different gases with the same mass and temperature always have the same average kinetic energy. This is one of the postulates of the kinetic theory of matter.
If we two objects A and B, they will have mass mA and mB and velocity vA and vB respectively. If K.E = 1/2mv^2 . Then it follows that
1/2mAvA = 1/2mBvB. Since the mass is the same it means the velocity of the two objects should be the same so that they have the same average kinetic energy.

A
