Which of the following pairs of spacetime events are separated by timelike, lightlike, and spacelike intervals? (these events are given by (ct, z, y,2) so you do not need to multiply the zeroth component by c). (a) (5,3,0,9) and (4,2,-1,8) (b) (8,6,7,5) and (10,7,8,6) (c) (2,3,6,0) and (0,3,7,0) (d) (-5,3,0,4) and (0,0,0,0) (e) (2,3,5,7) and (6,6,5,12)
