Suppose each object emitted a burst of light right now. Rank the objects from left to right based on the amount of time itwould take this light to reach Earth, from longest time to shortesttime:. -Star on the far side of the Andromeda Galaxy
-Star on the near side of Andromeda Galaxy
-Star on far side of Milky Way Galaxy
-Star near center of the Milky Way Galaxy
-Orion Nebulla
-Alpha Centauri
-Pluto
-Sun

the order of arrival is from highest to lowest

star other side of Andromeda> star near side of andromeda> other side of milky way   > center of the milky way> nevulosa orion> Pluto> Sum

Explanation:

The light that comes from stars and galaxies travels in a vacuum so its speed is constant and with a value of c = 3 108 m / s, so time will be directly proportional to the distance to the object

             x = c t

the order of arrival is from highest to lowest

star other side of Andromeda> star near side of andromeda> other side of milky way   > center of the milky way> nevulosa orion> Pluto> Sum

false

explanation:

boats, things on boats luggage are way more heavy then water.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
