Question

Please do this question for me please please please Two observers observe two events from different inertial frames of reference in uniform relative motion at a speed of 0.90c. Under what condition would the observers observe these events to be simultaneous? Write down all possible conditions under which the events would not be simultaneous for the two observers.

Answer 1

Since there is relative mutual motion of the observers, the condition under which the observers would observe these events to be simultaneous are motion toward each other at the same speed, and away from each other at the same speed.
