Question 1 of 30

Time left: 00:00

In inertial frame \(S\), two events occur at \[ A:\ (t_A,x_A)=(0,\ 0),\qquad B:\ (t_B,x_B)=(5.0~\mu\text{s},\ 900~\text{m}). \] Consider frame \(S'\) moving in the \(+x\) direction with speed \(v=0.60c\) relative to \(S\). Which statement about the time ordering and time separation in \(S'\) is correct?

Select one option.

In \(S'\), \(B\) occurs before \(A\), and \(\Delta t'=0\).
In \(S'\), \(A\) occurs before \(B\), and \(\Delta t'\approx 4.0~\mu\text{s}\).
In \(S'\), \(A\) and \(B\) are simultaneous.
In \(S'\), \(B\) occurs before \(A\), and \(\Delta t'>0\).
The time ordering must reverse because \(\Delta x\neq 0\).
