Which of the following terms refers to the gas that escapes a comet?

Physics
1 answer:
Gnoma [55]3 years ago
7 0

Answer:

The correct option is "a plasma tail"

Explanation:

Gases <u>escaping from a comet</u> are ionized by ultraviolent rays from the sun. These ionized gases are then carried away from the sun by the solar wind to form the plasma tail. While the plasma tail is made up of gases, the dust tail is made up of tiny solid particles (dust) that escapes from the comet and are also pushed away from the sun.

The regions of the Moon that are of higher elevation are known as the __________. These regions have a high albedo and display a
REY [17]

Answer:

lunar highlands

Explanation:

Seeing the moon from the earth we can see that some parts are more illuminated than others, these different regions of the moon have been assigned a name , and have different properties.

The brightest parts are called lunar highlands, because they are at a higher elevation than the darkest parts, called lunar marias.

The lunar highlands are seen from the earth a <u>whiter color than the rest of the moon</u> due to its altitude.

Satellite A orbits a planet at a distance d from the planet’s center with a centripetal acceleration a0. A second identical sate
leva [86]

To solve this problem it is necessary to use the concepts related to the Gravitational Force and Newton's Second Law, as far as we know:

F_g = \frac{GMm}{r^2}

Where,

G = Gravitational constant

M = Mass of earth (in this case)

m = mass of satellite

r = radius

In the other hand we have the second's newton law:

F = ma

Where,

m = mass

a = acceleration

Equation both equations we have,

ma = \frac{GMm}{r^2}

For the problem we have that,

<em>Satellite A:</em>

ma_A = \frac{GMm}{r^2}

<em>Satellite B:</em>

ma_B = \frac{GMm}{(2r)^2}

The ratio between the two satellites would be,

\frac{ma_A}{ma_B}= \frac{\frac{GMm}{r^2}}{\frac{GMm}{(2r)^2}}

Solving for a_B,

a_B = \frac{a_A}{4}

Therefore the centripetal acceleration of  A_B is a quarter of a_A
