***PLEASE HELP*** (you don’t have to answer all but at least 1 or 2 answers would help!!!)

Physics
1 answer:
Reptile [31]3 years ago

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.

please help! find magnitude and direction (the counterclockwise angle with the +x axis) of a vector that is equal to a + c
-BARSIC- [3]

Answer:

Option (2)

Explanation:

From the figure attached,

Horizontal component, A_x=A\text{Sin}37

A_x=12[\text{Sin}(37)]

     = 7.22 m

Vertical component, A_y=A[\text{Cos}(37)]

    = 9.58 m

Similarly, Horizontal component of vector C,

C_x  = C[Cos(60)]

     = 6[Cos(60)]

     = \frac{6}{2}

     = 3 m

C_y=6[\text{Sin}(60)]

    = 5.20 m

Resultant Horizontal component of the vectors A + C,

R_x=7.22-3=4.22 m

R_y=9.58-5.20 = 4.38 m

Now magnitude of the resultant will be,

From ΔOBC,

R=\sqrt{(R_x)^{2}+(R_y)^2}

   = \sqrt{(4.22)^2+(4.38)^2}

   = \sqrt{17.81+19.18}

   = 6.1 m

Direction of the resultant will be towards vector A.

tan(∠COB) = \frac{\text{CB}}{\text{OB}}

                  = \frac{R_y}{R_x}

                  = \frac{4.38}{4.22}

m∠COB = \text{tan}^{-1}(1.04)

             = 46°

Therefore, magnitude of the resultant vector will be 6.1 m and direction will be 46°.

Option (2) will be the answer.

Answer:

The 'little brain' attached to the rear of the brainstem is called the cerebellum. See the explanation below, please.

Explanation:

The cerebellum is in the back of the brain, it is small in size. It is responsible for functions such as integrations of sensory and motor pathways, balance, coordination of movements, posture.

When light is incident parallel to the principal axis and then strikes a lens, the light will refract through the focal point on the opposite side of the lens.

To find the answer, we have to know about the rules followed by drawing ray-diagram.

<h3>What are the rules obeyed by light rays?</h3>
  • If the incident ray is parallel to the principal axis, the refracted ray will pass through the opposite side's focus.
  • The refracted ray becomes parallel to the major axis if the incident ray passes through the focus.
  • The refracted ray follows the same path if the incident light passes through the center of the curve.

Thus, we can conclude that, when light is incident parallel to the principal axis and then strikes a lens, the light will refract through the focal point on the opposite side of the lens.
