Answer:
Gravity
Explanation:
When its altitude is matched by the pull of the Earth's gravity, a satellite circles Earth. The satellite will fly off into orbit in a straight line or crash down to Earth without this equilibrium.
By juggling two things, a satellite retains its orbit: its velocity (the speed it takes to travel along a straight line) and the gravitational force on it that the Planet provides. To resist the greater gravitational force, a spacecraft orbiting closer to the Earth needs more velocity.

Answer;
- REM sleep, Transitional sleep.
The dozing, half-awake state often seen in newborns is called REM sleep, transitional sleep.
-REM sleep is characterized by eye movement, increased respiration rate and increased brain activity. REM sleep is also referred to as paradoxical sleep because, while the brain and other body systems become more active, your muscles become more relaxed, or paralyzed.
-Dreaming occurs in REM sleep because of increased brain activity, but voluntary muscles become paralyzed. Voluntary muscles are those that you need to move by choice, for example, your arms and legs.
The correct statement about hydrochloric acid and acetic acid is : ( A )
The pH of a solution of hydrochloric acid must be less than the pH of a solution of acetic acid.
Given that pH is the inverse of concentration of H₃O⁺ ions , The stronger acid ( Hydrochloric acid ) dissociates in solution producing a maximum amount of H₃O⁺ ion, while the weak acid ( acetic ) will disassociate partially in a solution producing a lesser amount of H₃O⁺ ion.
Therefore the pH of a solution of hydrochloric acid must be less than the pH of a solution of acetic acid.
