14. A water diver of mass m = 80 kg, when breathes in up to his maximum capacity that is Vmax = 4.0 L of air, his body volume becomes V= 82 L. If he breathes in up to his maximum capacity and jumps into water, from what maximum depth (measured from the water surface to his chest) can he come to surface of the water without any swimming effort? Assume flesh and the bones in the body of the diver almost incompressible as compared to the air in his lungs. Density of water is p= 1000 kg/m³, atmospheric pressure is po = 1.0×105 Pa and accelerat- ion due to gravity is g = 10 m/s². Polsv-m) =lom

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.
