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:

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

yanalaym [24]

Answer:

Correct option are Basalt, gabbro and peridotite.

Explanation:

Igneous rocks like basalt, gabbro, dunite, diabase, and peridotite contains the olivine mineral. These are the dark coloured rocks and found within the surface of earth mostly in the areas around the tectonic plates. Olivine is known for its crystallization at high temperatures. It crystallize itself from the heat of the earth. Common olivine minerals are Forsterite, Fayalite, Monticellite and Tephroite.
