Answer 4

well for a start, the pressure of the gas enclosed must be greater than atmospheric pressure right?

Answer 5

yes, or else the water wouldnt be pushed further right

Answer 6

Answer 7

The pressure in a fluid at rest is the same for all points at the same level.
p=p_0 + ugh
u: density
h: height
g: gravity
p_0: atmospheric pressure (in this case).
p: pressure

I found (C) 1.5x10^5 Pa.

Answer 8

pressure of the gas = pressure of the liquid + atmospheric pressure

Answer 9

how did u calculate pressure of the liquid

Answer 10

p=p_0 + ugh = (1.0x10^5 Pa) + (1000 kg/m^3)(10 m/s^2)(5.0 m). The height is 5.0m because the pressure in a fluid at rest is the same for all points at the same level, the dotted line implies that the point where the gas encounters the water is the same as 5.0 m from te end of the tube.

thanks alot bro :)
