The pressure at 10 below the surface of the ocean is about2.00×105. Which of the following statements istrue? The weight of a column of seawater 1 in cross section and 10 high is about 2.00×105. The weight of a column of seawater 1 in cross section and 10 high plus the weight of a column of air with thesame cross section extending up to the top of the atmosphere isabout 2.00×105. The weight of 1 of seawater at 10 below...

40. The atmospheric pressure (force per unit area) on a surface at an altitude z is due to the weight of the column of air situated above the surface. Therefore, the difference in air pressure p between the top and bottom of a cylindrical volume element of height Az and cross-section area A equals the weight of the air enclosed (density ρ times volume V-: ΑΔε times gravity g), per unit area: Let Δ、→0 to derive...
