Gravity, acceleration, kinetic energy, the atmosphere
Solids: definite shape, definite volume
Because they are stiff and the molecules don't move around, they vibrate quickly.
Liquids: indefinite shape, definite volume
Because the shape or "fixed" area of liquids won't stay the same.
Gases: indefinite shape, indefinite volume
Because you've probably noticed, gases are set more freely, allowing molecules to move more freely than in solids and liquids.
x) Hope I helped! Which do you think it is?
<u>Answer:</u>
This is due to the apparent movement of the celestial bodies, seen from an observer centered on the Earth. If we did not have knowledge of the advances of science and the latest discoveries, we would think that the Earth is the center of the universe.
For example, for an observer on Earth as a reference system, the Sun moves every day from east to west, as do the planets and all the stars that we observe at night, which leads the observer to believe that those in motion are these bodies outside in the sky while the earth is still and fixed in the universe.
Keep in mind that this theory of geocentrism was widely accepted for a long time in antiquity, until the astronomer Nicolaus Copernicus proposed a completely different and opposite idea, heliocentrism (universe centered on the Sun).
However, at present it is known and accepted that the universe has no center, that the Earth revolves around the Sun and that in reality all the bodies of the universe are in movement.

The team of scientist will make sure the products are edible
Answer:
Negatively charged particles (electrons)
Explanation:
Plastic rod is charged -15.0 nC. It is clear that the charge on the rod is negative so the rod has gain excess of electrons.
When the rod touches a metal sphere charge on the plastic rod remains -10 nC, i.e. negative charge on the rod decreases. This is because negatively charged particles (electrons) are transferred from the plastic rod to the metal sphere.
