Answer:
A) 27209506.5 N 
B) 2393640 N
The force on the underwater vehicle is about 11.37 times the weight of the jetliner for comparison. 
Explanation:
Force du to depth of water is
F = pghA
P = density of salt water = 1025 kg/m3
g = acceleration due to gravity 9.81 m/s2
h = depth of water 11000 m
A = area pressure acts
Area = ¶r^2 = 3.142 x 0.280^2 = 0.246 m^2
Therefore 
F = 1025 x 9.81 x 11000 x 0.246
= 27209506.5 N
Weight of a jetliner with mass 2.44 × 10^5 kg is,
2.44×10^5 x 9.81 = 2393640 N
The force on the underwater vehicle is about 11.37 times the weight of the jetliner for comparison.

Answer:
200metters
Explanation:
because in one second hes going 10 metter in 20 second he will go 20×10=200
 
        
             
        
        
        
<h3>Reducing Surface Area.</h3>
If the surface area becomes smaller, the pressure becomes larger.
