Which of the following statements is true? the weight of a column of seawater 1 m2 in cross section and 10 m high is about 2.00×105 n. the weight of a column of seawater 1 m2 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 2.00×105 n. the weight of 1 m3 of seawater at 10 m below the surface of the ocean is about 2.00×105 n. the density of seawater is about 2.00×105 times the density of air at sea level.

Your pendulum clock which advances 1.0 s for every complete oscillation of the pendulum is running perfectly on earth at a site where the magnitude of the acceleration due to gravity is 9.80 m/s2. you send the clock to a location on the moon where the magnitude of the acceleration due to gravity is 1.65 m/s2.
