The spaceship S. Lem lands on Solaris (mass 4.04x1024 kg, radius 7.27x107 m, air pressure 1.22x105Pascal). The crew discovers pools of a mysterious substance of specific gravity 13.5. Find the pressure at the bottom of one pool of this substance, 90.9 m deep, in Pascals. Express your answer in scientific notation.
Gravitational constant = G = 6.67 x 10-11 N.m2/kg2
Mass of the planet Solaris = M = 4.04 x 1024 kg
Radius of the planet Solaris = R = 7.27 x 107 m
Gravitational acceleration on the surface of the planet Solaris = g
g = 0.051 m/s2
Air pressure on Solaris = P0 = 1.22 x 105 Pa
Density of water = 0 = 1000 kg/m3
Specific gravity of the mysterious substance = s = 13.5
Density of the mysterious substance =
= 13500 kg/m3
Depth of the pool = H = 90.9 m
Pressure at the bottom of the pool = P
P = 1.846 x 105 Pa
Pressure at the bottom of the pool = 1.846 x 105 Pa
