Scientists have found evidence that Mars may once have had an ocean 0.500 km deep. The acceleration due to gravity on Mars is 3.71 m/s². a. What would be the gauge pressure at the bottom of such an ocean, assuming it was freshwater? b. To what depth would you need to go in the earth's ocean to experience the same gauge pressure? See problem 1 for the density of sea water.

Density of Solids

The density of a substance refers to how much matter is present in a given amount of space. It is expressed as the ratio of the mass of the substance to its volume.
