consider a cube of sides l0 traveling parallel to one side. At what speed would the density of the cube double?

Solutions

Expert Solution

Initial state (rest) :

                     density = , mass = , length =

                    density, = mass/volume =    

Final state :

                    density = ,

                    mass = ,       length =

                   density, is =

                                          

            For

                           

                     

                       

therefore the density will be doubled if it travels with a speed of 0.707c
