Which statement best describes an effect of tension acting on Earths crust HEEEEEEELPP PLEASE

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:

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

Do you think migration was a voluntary move or involuntary? Why?

shtirl [24]

Answer:

People who flee persecution and violence in their own country are considered asylum seekers while the people who decide to move to another country in order to seek employment and better life opportunities are considered migrants. Migrants can be legal, moving threw documentation. Migrants are usually people with a strong resources in order to prepare their journey and arrival in the country of the destination. They save money, they gather the information about the trip and the destination and about the potential employment there, like how mast Europians or Asians come to america. They speak to friends and family at the destination who will help them upon arrival. They may speak to travel agents, potential employers at destination or middlemen of different sorts. They may try to learn the language of the destination country. In short, migrants clearly make decisions and take up the actions in order to prepare for their migration. This does not necessarily mean their migration is voluntary. The reasons for leaving their country of origin may have to do with circumstances that are beyond their the control. Migrating is not a decision taken easily, it involves high costs. They may do this to help family

It can be both

People either can be made to move involuntarily, or forced, or are put in situations that encourge relocation, or reluctant, or if they choose to migrate ,or voluntary.

Where are glaciers found? Check all the apply In the ocean In the tropics At earth's pole At high latitudes At high altitudes

vfiekz [6]

The correct answers are:

- At Earth's pole;

- At high latitudes;

- At high altitudes;

The glaciers are a frozen ice mass that is slowly moving from a higher toward a lower region. For them to exist, specific conditions are required, the most important of which is that the climate is very cold throughout the whole year. The places that provide suitable conditions for the existence of glaciers are the Antarctica (where most of them are located), the island of Greenland, as well as the very high mountains that have cold weather throughout the whole year, especially at their highest parts, like the Alps and the Himalayas.

Which phrases describe air density ? Select three options.

Phantasy [73]

Answer: The correct options are:

exerts more pressure as it increases

measures how tightly molecules are packed

equals mass divided by volume

Explanation:

Air density can be described as mass per unit of volume of the volume of air.

As the altitude increases, the air density tens to decrease. Hence, option A is not correct.

The density of the air determined how many atoms of air can occur in a particular volume, In other words, it determines how tightly or loosely atoms of air are packed in a particular volume.

Hence, when the air density will increase, the molecules will be more tightly packed and the pressure will be more.
