Answer:
Rarefactions
Explanation:
The sound waves travel in compressions and rarefactions.
As the name suggests compressions are the areas which particles are closer than their usual positioning.
In rarefactions the vibrating particles can be observed further apart than the usual.

Answer:
Explanation:
It can be assumed that the finally it reaches to a height of 16 m. He starts from 6.5 m
Mass, m = 1700 Kg
Let 
is the change in potential energy. It is given by:
So, it will lose 158270 joules of energy in friction. Hence, this is the required solution.
