<em>Hey mate, here's ur answer</em>
<em>-------------------------------------------------------------</em>
<u><em>Loudness</em></u><em> refers to how a sound seems to a listener, whether it's loud or soft. </em>
<em>___________________________</em>
<u><em>Intensity </em></u><em> is the sound power per unit area. It is independent of the sensitivity of the human ears.</em>
<em>___________________________</em>
<em>The loudness of a sound relates the intensity of any given sound to the intensity at the threshold of hearing. It is measured in decibels (dB).</em>

Answer:
1.been both -ve charged or both +be charged particles
2. 3.52mC
Explanation:
For the charge particle to cause an extension or movement of the string from its unrestrained position they would have been both -ve charged or both +be charged particles that's because like charges repel.
Now the Force sustain by the extended string is
F = Ke;
Where K is the force constant of the string, 320 N/m
e is the extension,0.033 m
F = 320 × 0.033 =10.56N
2.But according to columns law of charge;
F = kQ1 Q2
But Q1=Q2{ since the charge are of the same magnitude}.
Hence F = KQ^2
Where K is columns constant =9×10^9F/m
Hence Q=√F/K
Q= √10.56/9×10^9
=3.52×10^-3C
= 3.52mC
Answer:
The answer would be C. 8 N

This one is easy :) it is called a "Hypothesis"!
