Homework Statement
The pressure at 10 m below the surface of the ocean is about 2.00×10^5 Pa.
Which of the following statements is true?
a. The weight of a column of seawater 1 m^2 in cross section and 10 m high is about 2.00×10^5 N.
b. The weight of a column of seawater 1 m^2 in cross section and 10 m high plus the weight of a column of air with the same cross section extending up to the top of the atmosphere is about 2.00×10^5 N.
c. The weight of 1 m^3 of seawater at 10 m below the surface of the ocean is about 2.00×10^5 N.
d. The density of seawater is about 2.00×10^5 times the density of air at sea level.
I may sound a bit greedy but if you can please explain why it is that and why others aren't right
