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:

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

Geomorphology is an eclectic science because it is a complex science that has to do with the explanation of how landforms are formed at various scales.

<h3>What is geomorphology?</h3>

It should be noted that geomorphology simply means the study of landforms, and sediments on Earth surface.

Why has the threat from acid deposition been steadily increasing in the 21st century?

Alexus [3.1K]

The threat from acid deposition has been steadily increasing in the 21st century because of the increase in the number of industries during this period. The acid particles get trapped in the atmosphere and falls as raid on earth. These acid particles are increasing with the booming of the industrial sector.
