Answer:
(4.31±0.38) million Solar masses.
Explanation:
The galactic center is the center of the milky way around which the galaxy rotates. It is most likely the location of a supermassive black hole which has a mass of (4.31±0.38) million Solar masses. The location is called Sagittarius A*.
As there is interstellar dust in our line of sight from the Earth infrared observations need to be taken.
The answer is c, positron.
It goes from Kinetic when it is at rest to potential on its way to the bottom. There is also friction but very few people care about that.
Answer:
9.2 m/s
Explanation:
v^2 = u^2 + 2as
u = 4.71
a= g * sin(8.30)
v= sqrt( 4.71^2 + 2 * 9.8* sin( 8.30 deg) * 22) = 9.2 m/s
