(ii) In solid, the particles are arranged very closely and tightly packed therefore the sound waves in solid have the fastest speed or travels fastest in comparison to liquid and gas.
(iii) Slower than solid is the travel of sound waves in liquid than in gas(least dense, particles are far apart.
From what i know it is c. it is a lever
If the only thing remaining is Oxygen then it is 51.16%.
The total charge on the helix is
- Q =

Height of one turn = 
Horizontal distance in one turn = 
<h3>
length of spring in one turn is</h3>

So, the total length of spring

Therefore, charge on spring
