itan's orbital radius is about 1222000 km and its orbital period is just under 16 days. From this information, estimate the mass
maksim [4K]

Answer:

5.67\cdot 10^{26} kg

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:

\frac{GMm}{r^2}=m\frac{v^2}{r}

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

M=\frac{v^2r}{G}

Also, we can write the orbital speed as the ratio between the length of the orbit (circumference of the orbit) and orbital period, T:

v=\frac{2\pi r}{T}

Substituting into the equation for M,

M=\frac{4\pi^2 r^3}{GT^2}

Here we have:

r=1,222,000 km = 1.222\cdot 10^6 km = 1.222\cdot 10^9 m is the orbital radius

T=16 d \cdot 86400 s/d=1.38\cdot 10^6 s is the orbital period

Substituting, we find the mass of the Saturn:

M=\frac{4\pi^2 (1.222\cdot 10^9)^3}{(6.67\cdot 10^{-11})(1.38\cdot 10^6)^2}=5.67\cdot 10^{26} kg

Why have many educated people left modern iran?
sineoko [7]
Educated people don't need to be in Iran. Iran doesn't provide colleges or any type of higher education that awards degrees. Iran is also a dangerous place, especially for women, seeing as you have gangs or terrorist groups such as The Taliban or Isis.
