Clock A travels to the right at a speed v relative to clocks B and C. As A passes B, all clocks read 12:00 (shown in the figure below). These readings could be seen simultaneously by a stationary observer O, midway between B and C, though O would make the observation at some later time (a) Clock C reads 6:00 as A passes C. What does clock A read? P.M. (b) At what time does observer O see the three clocks read 12:007 P.M.
