-- There are 80 protons in the nucleus of every atom of Mercury,
but only 8 of them in the nucleus of an atom of Oxygen.
-- Mercury must be warmer than 357°C in order to boil, but Oxygen
must only be warmer than -183°C.
-- Mercury must be colder than -39°C in order to freeze, but Oxygen
must be colder than -219°C.
-- Oxygen is required for human life. Mercury is a deadly poison.
Answer:
Explanation:
according to resultant of two parallel forces,
Fpivot = Fobject + Fbricks
so that, the net force is zero
protons, the electrons and neutrons change but NEVER the protons.
If they have the same momentum, then
m₁ v₁ = m₂ v₂
If m₁ > m₂, then we must have v₁ < v₂ to preserve the equality.
The object with the larger speed - the second object - thus has more kinetic energy.
Because one object can have more things in it. I learned it a t school today.
