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:

Answer: Sweden does not charge tuition for both public and private colleges. Denmark spends 0.6% of its total GDP on subsidies for college students. Finland also provides students with generous scholarships and grants to finance their studies or living expenses. Ireland has paid tuition fees for most full-time undergraduate students since 1995. Iceland tuition fees vary by your major because of differences in both the cost of studies and labor-market demands. Norway pays the most for college subsidies, spending 1.3% of its annual GDP. The Czech Republic provides small subsidies to help students with college costs aside from covering the cost of tuition.
