What is the time separation delta t between the two lightning bolts determined by a second observer in reference frame S moving at a speed of 0.90c along the collinear x-x'-axis? delta t = ? sIn our inertial reference frame, we see a particle accelerating with a velocity dx/dt = ( 1 - e-gt )1/2 in units where c = 1 (speed of light) When we watch the particle's trajectory from t=0 to t=T, how much time passes in the particle's non inertial frame? Now express the answer such that T and the time have units of seconds instead of meters What's the 4-velocity in units c=1?

ORED FRAME: A particle traveling at a constant velocity decayed in 3.8 μs. Event A was when. came into being (when it was 'born') & event B was when it decayed (when it 'died'). □ ORANGE FRAME: Event C happened at (5 m, -9 m, -8 m) and event D happened at (-5 m, -0.9 m, -8 m). O YELLOW FRAME: The distance between where event E occurred and where event F occurred was 4 m. □ GREEN FRAME: A rocket was traveling at a constant velocity when it passed through a stationary tunnel. Event G was the front of the rocket entering the tunnel and event H was the the front of the rocket leaving the tunnel. BLUE FRAME: A stationary rocket was engulfed by a hollow cylinder that was moving at a constant velocity. Event J was the front of the rocket entering the cylinder and event K was the the front of the rocket leaving the cylinder.For an observer in a reference frame S, two events occur at the same location, with thesecond event occurring 2.5 s after the first.For an observer in reference frame S’, the second event occurs 4.2 s after the first. How faraway from each other did the two events occur in S’?
