Gravity is the force of attraction between objects. Gravity is that force of attraction that will cause hydrogen gas in a nebula to clump together overtime. These hydrogen atoms will form a spinning cloud of gas within the nebula.
As collisions between the atoms become more frequent, the temperature within the cloud will rise.
As the cloud gets more massive the greater the force of gravity will be and so it will attract even more gas to the spinning cloud. When the temperature reaches fifteen million degrees Celsius, nuclear fission begins and a star is born.
<h2>
Answer: zero (0)</h2>
Explanation:
The orbit of a body around another in space, is described by six orbital elements that determine its orientation, position, size and shape.
In the specific case of the shape of the orbit, this is determined by its <u>eccentricity</u>, which varies between 0 and 1 in the case of closed orbits (circle and ellipse). When the eccentricity is 0, the shape of the orbit is circular, when this value begins to vary until approaching 1 (without reaching 1), the shape of the orbit becomes more elliptical.
In this sense, a circular orbit will have an eccentriciy of zero.
Answer:
Air vacuum.
Explanation:
Air may seem like nothing, but there are tons of molecules in it. Air takes up space. When Angelica inhales, the air rushes into into and escapes the cup. Since theres no air anymore, the cup collapses because thereis no more space in it. She removes the air from the cup and it creates a vacuum inside, sucking the sides of the cup in.
The water runs out the holler and through the creek an then the molecules sedimentate
That's tin
d = m/v
42.5/ 5.8
which comes around 7.3 g/ml and matches with the density of the tin metal
