Out of the solar system parts, we can see the sun, a few planets, some meteorites and comets.
Rest all is not visible through naked eyes
By utilizing a galaxy model that accurately explains all of the data that has been collected thus far.
<h3>Suppose it turns out that one in 1 million stars has a planet that at some point in its history is home to an advanced civilization. Then the total number of civilizations that have arisen in our galaxy would be closest to _____. Assume there are about 100 billion stars in the Milky Way galaxy.</h3>
It has been estimated that our galaxy has something close to 100,000 different civilizations.A galaxy is a collection of stars (or solar systems), gas, and dust that is located in a certain area of the universe.
It has been suggested that the Milky Way, the galaxy in which we reside, is replete with extinct civilizations.In conclusion, there are probably close to 100,000 civilizations in our galaxy as a whole.

Answer:
6 m/s
Explanation:
To determine the change in speed of the object, we just need to determine its speed at t = 30 s and at t = 20 s, and then calculate the difference.
The speed at t = 30 is:
v = 6 m/s
While the speed at t = 20 s is:
u = 0
Therefore, the change in speed is:
Answer:
Frick is pushing harder
Explanation:
if Frack weighs more and he was pushing harder they would be moving, but if Frick pushes harder then they wont move
Answer:
How to find the maximum height of a projectile?
if α = 90°, then the formula simplifies to: hmax = h + V₀² / (2 * g) and the time of flight is the longest. ...
if α = 45°, then the equation may be written as: ...
if α = 0°, then vertical velocity is equal to 0 (Vy = 0), and that's the case of horizontal projectile motion.
Explanation:
