Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.

What depth of mercury creates a pressure of 1.00 atm?
Scuba divers want to explore the Mariana Trench, the deepest location on Earth, at 11,034m deep. Assuming the pressure at the boat is atmospheric pressure (101,000Pa) and the water density is 1000kg/m3, what pressure would they feel at this depth? If the human body is able to withstand up to 3x106Pa of pressure, based on your answer, would a person be able to scuba dive to that depth?
How do you convert pressure units like millimeters of mercury, centimeters of water, and inches of mercury into units like newtons per meter squared without resorting to a table of pressure conversion factors?
