The second part of the question can not be fully answered because it is not proven that there is or isn’t others life forms in this universe. personallyi think that there is but whatva

The "Milky Way" is the name we call OUR Galaxy ... the one we're in. There are several billion OTHER galaxies besides the one we're in.

There are SO MANY stars in the Milky Way, and SO MANY other galaxies, and SO MANY stars in every other Galaxy, and SO MANY planets around SO MANY stars, that most scientists believe that it's a sure bet that there's life in other places, or that there used to be, and it's a sure bet that aliens exist in other places, or that they used to.

But we've never seen ANY evidence of ANY life in ANY other place except Earth.

Yet.

A 91-kg astronaut and a 1300-kg satellite are at rest relative to the space shuttle. The astronaut pushes on the satellite, givi

WARRIOR [948]

Answer:

18.2145 meters

Explanation:

Using the conservation of momentum, we have that:

$m1v1 + m2v2 = m1'v1' + m2'v2'$

m1 = m1' is the mass of the astronaut, m2=m2' is the mass of the satellite, v1 and v2 are the inicial speed of the astronaut and the satellite (v1 = v2 = 0), and v1' and v2' are the final speed of the astronaut and the satellite. Then we have that:

$0 + 0 = 91*v1' + 1300*0.17$

$v1' = -1300*0.17/91 = -2.4286\ m/s$

The negative sign of this speed just indicates the direction the astronaut goes, which is the opposite direction of the satellite.

If the astronaut takes 7.5 seconds to come into contact with the shuttle, their initial distance is:

$distance = 2.4286 * 7.5 = 18.2145\ meters$

What is the difference between clastic and bioclast?

Grace [21]

The main difference is the source of the sediment that the rock is formed from. Clastic sedimentary rocks are formed mostly from silicate sediment derived by the breakdown of pre-existing rocks. Bioclastic rocks are formed by the accumulation of fragmented organic remains (such as shell-sand) - i.e. the sediment is of biological rather than non-biological origin.
