Volcanoes are not randomly distributed over the Earth's surface. Most are concentrated on the edges of continents, along island chains, or beneath the sea forming long mountain ranges.

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:

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

Complete Question

With surface temperatures estimated at minus 230 degrees Farenheit, Jupiter's moon Europa has long been considered far too cold to support life, and with 60 square miles of water though to be frozen from top to bottom

A) Europa has long been considered far too cold to support life, and with

B) Europa has long been considered far too cold to support , its

C) Europa has long been considered as far too cold to support life and has

D) Europa, long considered as far too cold to support life, and its

E) Europa, long considered to be far too cold to support life, and to have

Answer:

B) Europa has long been considered far too cold to support life, its

Explanation:

Options C, D, E are incorrect because when looking at the sentences in these options,

Option A) ' A) Europa has long been considered far too cold to support life, and with' is also wrong as well because comma(,) and 'and' were not used properly in the sentence

Option C) 'Europa has long been considered as far too cold to support life and has' is wrong as well.

Option D) 'Europa, long considered as far too cold to support life, and its' is wrong because there is no verb present

Option E) 'Europa, long considered to be far too cold to support life, and to have' is wrong because it has no verb also.

Option B is the only correct option because the noun in the sentence was modified properly.

The noun in sentence = Europa has long been considered far too cold to support

Modifier= 'its 60 square miles of water though to be frozen from top to bottom'

Our environment can change our behavior in many aspects. Suppose you want to play golf with your friends, as you predicted it is going to be a sunny day but suddenly the environment changes and it converts into a rainy day then you have to change your plan.
