`1.Many galaxies exist.
3.Most galaxies are moving away from us.
4.Uniform background radiation is detected in every direction.
Explanation:
The Big bang theory is a theory explaining the formation of the universe from the early stages to today.According to the theory , the universe started as a hot ,small , & dense super-force with no singularity(atom, structure, form).The evidence of this theory include;
- systematical shifting of the galaxies away from us
- A radiation called cosmic microwave background radiation only explained by the theory
- Larger redshifts causing great drop off in the number of quasar
- Abundance of different elements in the universe such as hydrogen and lithium checked through spectra of oldest stars and gas clouds.

Answer:
the lowest point, where the amount of energy is the greatest
Explanation:
The correct answer is "The roller coaster cars determine the amount of kinetic energy in the system. It’s the only part of the system that moves. Kinetic energy depends on the velocity and mass of a moving object."
Explanation:
In a solid, molecules are held together by strong intermolecular forces of attraction. As a result, they are unable to move from their initial place but they can vibrate at their mean position.
Hence, in solid substances the molecules have low kinetic energy.
Whereas in liquids, the molecules are held by less strong intermolecular forces of attraction as compared to solids. Due to which they are able to slide past each other. Hence, they have medium kinetic energy.
In gases, the molecules are held by weak Vander waal forces. Hence, they have high kinetic energy due to which they move rapidly from one place to another leading to more number of collisions.
Hence, gases are able to expand more rapidly as compared to liquids.
Therefore, we can conclude that in gaseous phase the space between particles tend to increase.

It represents double composition
