Answer: 53 kPa
Explanation:
Absolute pressure is a pressure value referred to absolute zero or vacuum. This value indicates the total pressure to which a body or system (the chamber in this situation) is subjected, considering the total pressure acting on it.
In this sense, the equation that will be useful in this case is:
(1)
Where:
is the atmospheric pressure
is the vacuum pressure
is the absolute pressure
Isolating from (1):
(2)
(3)
Finally:
This is the absolute pressure in the chamber

u need to explain more !!
Explanation:
Answer:
T = 0.96 seconds
Explanation:
Given that,
The speed of wave, v = 2.6 m/s
The distance between wave crests, 
We need to find the period of the wave motion. Let T be the period. So,
So, the period of the wave motion is equal to 0.96 seconds.
