Explanation:
In an acid solution, the concentration of H₃O⁺ ions is more than OH⁻
In a basic solution, the concentration of OH⁻ is more than that of H₃O⁺
By definition:
According to Arrhenius theory;
An acid is a substance that interacts with water to produce excess hydroxonium ions, H₃O⁺ in an aqueous solution. The hydroxonium ions formed as a result of the chemical bonding between the oxygen of water molecules and the protons released by the acid due to its ionization.
A base is a substance that interacts with water to produce excess hydroxide ions, OH⁻ in an aqueous solution. The common bases are NaOH and KOH

Explanation:
There must be differences in temperature, pressure and composition within a liquid metal core inside the planet, since this produces a motion of the liquid metal, generating electric currents, which produce magnetic fields, that align, combining their effect to produce a large field Magnetic that envelops the planet.
Answer:
They have each lost the same amount of potential energy. (The lost potential energy is converted to kinetic energy.)
Answer:
A star is a huge sphere of very hot, glowing gas. Stars produce their own light and energy by a process called nuclear fusion. Fusion happens when lighter elements are forced to become heavier elements. When this happens, a tremendous amount of energy is created causing the star to heat up and shine.
