Answer:
Erosion can happen very quickly or very slowly.
e.g splash erosion occurs slowly while gulley erosion occurs very fast.
As we know that
P.E. = mgh
where,
P.E. = Potential energy of the object =?
m= mass of object= 3kg
g= acceleration due to gravity = 9.8 ms^-2
h = height between object and animal = 0 m
Then
P.E. = 3× 9.8 × 0 = 0 Joules or 0J

Answer:
The answer to your question is Protons = 78, Neutrons = 117, Electrons = 76
Explanation:
¹⁹⁵Pt²⁺
Protons are equal to the atomic number, Platinum has an atomic number of 78 so the number of protons = 78.
The number of neutrons = Mass number - Number of protons
= 195 - 78
= 117
The number of electrons is equal to the number of protons - two, we know this because of the 2+ exponent next to the Platinum symbol.
Number of electrons = 78 - 2
= 76
A neutron has a neutral charge.
A proton is positive while an electron is negative. Neutrons have no charge.
