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.

Big Ben, a large artifact in England, has a mass of 1x10^8 kilograms and the Empire State Building 1x10^9 kilograms. The distanc
TiliK225 [7]

Answer:

The force, exerted by Big Ben on the Empire State Building is 2.66972 × 10⁻⁷ N

Explanation:

The question relates to the force of gravity experienced between two bodies

The given parameters are;

The mass of Big Ben, M₁ = 1 × 10⁸ kg

The mass of the Empire State Building, M₂ = 1 × 10⁹ kg

The distance between the two Big Ben and the Empire State Building, r = 5,000,000 meters

By Newton's Law of gravitation, we have;

F=G \times \dfrac{M_{1} \times M_{2}}{r^{2}}

Where;

F = The force exerted by Big Ben on the Empire State Building and vice versa

G = The universal gravitational constant = 6.67430 × 10⁻¹¹ N·m²/kg²

M₁, M₂, and r are the given parameters

By plugging in the values of the parameters and the constant into the equation for Newton's Law of gravitation, we have;

F=6.67430 \times 10^{-11} \times \dfrac{1 \times 10^8 \times 1 \times 10^9}{(5,000,000)^{2}} = 2.66972 \times 10^{-7}

The force, 'F', exerted by Big Ben on the Empire State Building is F = 2.66972 × 10⁻⁷ N.

It has to be the last one because whenever lights are turned on it decreases because all lights are on at the same time. It's good to just have one light on. It doesn't use as much electricity.
