A liquid is used to make a mercury-type barometer, as described in section Pressure in a Fluid. The barometer is intended for spacefaring astronauts. At the surface of the earth, the column of liquid rises to a height of 2185 , but on the surface of Planet X, where the acceleration due to gravity is one-fourth of its value on earth, the column rises to only 705 Part A: Find the density of the liquid. kg/m^3 Part B: Find the atmospheric pressure at the surface of Planet X.
