Answer: 4.4 cm.
Explanation:
Rise of water in the smaller tube= h1=8.8 centimeter(cm)
Radius of the smaller tube= r
Rise of water in the larger tube= h2 (in centimeter).
The radius of the larger tube is twice that of the smaller tube means that;
The radius in the larger tube is 2r ( 2 multiply by the radius r, of the smaller tube)
Using Jurin's law;
height or rise of liquid is inversely proportional to its radius, r.
That is; hr= constant.
Therefore, we have;
h1 × r1 = h2 × r2.
Rise in smaller tube × radius of the smaller tube = height of the larger tube × radius of the larger tube.
8.8 cm × r = h2 × 2r
= (8.8cm)r = (h2) 2r
Divide both sides by 2r, we then have;
8.8cm r/ 2r = h2
h2= 4.4cm
Therefore, the height or rise in large tube is half of that of the smaller tube.
The final atmospheric pressure is 
Explanation:
Assuming that the temperature of the air does not change, we can use Boyle's law, which states that for a gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume. In formula,
where
p is the gas pressure
V is the volume
The equation can also be rewritten as
where in our problem we have:
is the initial pressure (the atmospheric pressure at sea level)
is the initial volume
is the final pressure
is the final volume
Solving the equation for p2, we find the final pressure:
