The reason that the Roman Republic created a system of
checks and balance as this allowed them from preventing a specific group in
obtaining more power than of the others in which based on the choices above,
the correct answer is letter D.
Copernican heliocentrism is the name given to the astronomical model developed by Nicolaus Copernicus and published in 1543. This model positioned the Sun at the center of the Universe, motionless, with Earth and the other planets orbiting around it in circular paths, modified by epicycles, and at uniform speeds.
The major features of Copernican theory are: Heavenly motions are uniform, eternal, and circular or compounded of several circles (epicycles). The center of the universe is near the Sun. Around the Sun, in order, are Mercury, Venus, the Earth and Moon, Mars, Jupiter, Saturn, and the fixed stars.
Allows calculation of planetary orbital periods around Sun. Allows geometric calculations of planetary distances from Sun. These show nice regularity: more distant planets have longer periods, move slower. Easier to calculate planetary positions than with Ptolemaic model.
I hope this helps!
I think that the answer is probably B.
The Irrawaddy, Chao Phraya, and Mekong Rivers all flow from B- North to South.
I hope this helps! :)
