An object with a density of 1.2 kg/liters and a mass of 23.2 kg is fully submerged in seawater (\rhoρ = 1029 kg/m^33). Calculate the net-force acting on the object (i.e. the sum of the buoyant force pointing up and the gravitational force pointing down). Assume that a positive net-force means the force points up and thus the object is positively buoyant. Please enter a numerical answer below. Accepted formats are numbers or "e" based scientific notation e.g. 0.23, -2, 1e6, 5.23e-8 ------N

A mercury barometer is an instrument in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column. The height of the column varies with atmospheric pressure. What is the height of the mercury column if you are on top of a mountain where the pressure of the atmosphere is 0.583 atm? The density of mercury is 13.6 \times 10 ^313.6×103 kg/m^33.
