Compression and rarefaction are two phenomenon occurs in longitudunal wave!
when there is denser particle gathering in that wave , there we called it compression and the rarer part of particles is rarefaction !

The net force on q₃ will be 17.51 N. The net force is the algebraic sum of the two forces on the pleading q₃
<h3 /><h3>What is Columb's law?</h3>
The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
The force,by the charge q₁ on the q₃;

The force,by the charge q₂ on the q₃;

The net force is the sum of the two forces;

Hence, the net force on q₃ will be 17.51 N.

Your answer is Chemical to Thermal and Electromagnetic c:
<h3>
Answer:</h3>
pH = 5
<h3>
Explanation:</h3>
<u>We are given;</u>
- Concentration of a solution HI as 0.00001 M
We are required to calculate the pH of Hydronium ions.
- When the acid dissociates in water to;
HI + H₂O → H₃O⁺(aq) + I⁻(aq)
- The concentration of H₃O⁺ ions is 0.00001 M\
- We need to know that pH = -log[H₃O⁺]
Therefore;
pH =-log 0.00001 M
= 5
Thus, the pH of the hydronium ions is 5
