Answer:
gravitational
Explanation:
Potential energy that is related to an object's height above the ground is known as gravitational potential energy.
Potential energy due to the position of an object above Earth’s surface is called gravitational potential energy.
The answer is van der Waal force, or to be precise, London dispersion forces.
This type of force is present between all molecules and they are caused by electrons that are orbiting the atom cores. The moving of the electrons can result in making the atom temporary dipole due to the asymmetry of electron distribution around the core. This temporary dipole now can interact with other atoms leading to an electrostatic interaction. The more electrons an atom has, the stronger are these intermolecular forces.

Answer:
Mixtures contain 2 solid substance and other mixtures are soluble in a particular liguid solvent ans so others constituent is insoluble in it.
Explanation:
Answer: 2 : 1
Explanation:
Cation :
Ca - calcium = atomic number = 20
Electron dot configuration : 2, 8, 8, 2
Ca losses 2 electrons in its outermost shell and thus has a charge of 2+ in other to attain a stable octet state.
Anion:
F - has 7 valence electrons and thus needs 1 electron to achieve a stable octet state, hence it accepts one electron has has a charge of (-1)
Therefore,
Ratio of cation (+) to negative (-) = 2 :1
