Answer:

1. B. Contract

2. C. In dark matter and dark energy

3. A. In denser regions with little space between atoms

Explanation:

1. We know that the galaxy consists of a cluster of stars with their respective planets rotating around the center of the Galaxy, i.e. a galaxy is a formation of millions or billions of stars depending on its size. In the center of each galaxy is a black hole, this black hole will absorb all kinds of matter and in turn energy. black holes are the densest objects in the universe and no one escapes their gravity. And finally every star in the Galaxy will be absorbed by the black hole.

2. The most logical explanation to this question is that baryonic matter is the conformation of dark matter and dark energy. Everything that relates energy and dark matter can be grouped as baryonic matter.

3. After the explosion of a star originates the birth of a new one, with new planets, before the new conformation the explosion generates clouds of gas very dense, which are near the site of the explosion, this way, the material more dense contracts forming a new star, the remaining material of the dense gas clouds are grouped if you do not have the enough energy and with other requirements to form rocky planets and the clouds less dense than they were in the outside part of the bang form the gas planets. Therefore always in each group of planets, the closest to the star will be solid planets while the Outer Ones will be gaseous planets.

Which is a correct statement of what occurs at a turbine during electricity production?
jarptica [38.1K]

Answer:

The turbine is rotated and rotates the generator to produce electricity.

Explanation:

Within a turbine enters the superheated steam which is at high pressure and high temperature, this steam is previously formed in the boiler when the steam enters the turbine hits each one of the blades of the turbine making it rotate at a given speed, the turbine shaft is coupled to the shaft of an electric generator and thus generates electricity.

It is also important to say that when the steam comes out of the turbine comes out at low pressure, this way the internal operating process is carried out within the turbine.

How do you work out instantaneous speed?
Alik [6]
To calculate instantaneous speed, we need to divide part of the total distance traveled by time. However, we don't want to use the distance of the entire trip, because that will give us average speed.
