5} Time is a] simultaneous in all frames d] dependent on the frame of reference b1 absolute e} never changing cl the same for different frames of reference 5} The equation E = Inc2 illustrates that a} energy:r can be converted into mass d] a and c are correct b1 total amount of mass and energv does not change e] b and c are correct cl Matter can be converted into energv I". Newtonian mechanics are valid a] in all frames of reference c] on Earth onlv b} in relativistic frames of reference d] in inertial frames of reference 8. A space ship traveling with a velocity v =0.6 c approaches a space station housing a light beacon. When the ship is still some distance away, the station turns on the light beacon. As the beam of light passes the space ship, an observer in the space ship will measure the velocity of the light beam as: a) 2 c c) 0.4 c b) c d) 1.6 c
