What is the ratio ioc/mc2 for a particle with mass m so that the total energy of the particle is 3.59 times its rest energy? Number n Units v Quasars are thought to be the nuclei of active galaxies in the early stages of their formation. Suppose a quasar radiates energy at the rate of 1041 W. At what rate is the mass of this quasar being reduced to supply this energy? Express your answer in solar mass units per year (smu/Y), where one solar mass unit (1 smu = 2.0 X 1030 kg) is the mass of our Sun. Number n Units v Current Attempt in Progress A spaceship at rest in a certain reference frame S is given a speed increment of 0.50 c. Relative to its new rest frame, it is then given a further 0.5 c increment.This process is continued until its speed with respect to its original frame S exceeds 0.999 c. How many increments does this process require? Number i Units
