Answer:
Explanation:
For a satellite in orbit around a planet, the gravitational force between the planet and the satellite is equal to the centripetal force that keeps the satellite in circular motion.
So, we can write:
where
G is the gravitational constant
M is the mass of the planet
m is the mass of the satellite
r is the orbital radius of the satellite
v is the speed of the satellite
The equation can be rewritten as
Also, we can write the orbital speed as the ratio between the length of the orbit (circumference of the orbit) and orbital period, T:
Substituting into the equation for M,
Here we have:
is the orbital radius
is the orbital period
Substituting, we find the mass of the Saturn:
Brazil is home to the largest population of Asian Latin Americans, at some 3.5 million. The highest ratio of any country in the region is 5%, in Peru.

Out of the 4 options it would be most likely that western Europe's population would stabilize this way since it is one of the oldest and advanced, so rapid growth would be low and death rates reduced by advances in medicine.</span>
