The pressure at 10 m below the surface of the ocean is about2.00 10^5 Pa. Which of the following statements istrue? The weight of a column of seawater 1 m^2 in cross section and 10 m high is about 2.0010^5 N. The weight of a column of seawater 1m^2 in cross section and 10 m high plus the weight of a column of air with thesame cross section extending up to the top of the atmosphere isabout 2.0010^5 N The weight of 1 m^3 of seawater at 10 m below the surface of the ocean is about2.0010^5 N.Now consider he pressure at 20 m below the surface of the ocean.The density of seawater is about2.0010^5 times the density of air at sealevel. This pressure is twice that at a depth of 10 m.the same as that at a depth of 10 m. equal to that at a depth of 10 m plus the weight of a column of seawater 1 m^2 in cross section and 10 m high. equal to the weight of a column of seawater 1m^2 in cross section and 20 m high
