1. It is debated that a certain civilization knew how to forge metals. To determine the density of a chunk of metal found at an archeological site, the metal is placed in a cylinder of water and displaces 13.4 cm' of water. If the mass of the metal is 108.6 g, what can be said about the civilization? Explain. (Hint: Prin-7.29 g/cm' and pcopper=8,9 g/cm')

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.
