MC 1
Ann and Bob are in inertial frames in relative motion along the common x-axis, carrying identical metersticks. Ann arranges her meterstick so that it lies along the x-axis, places flash bulbs at each end of the meterstick, and sets off the flashes such that she sees them occur simultaneously. Bob also sets his meterstick along the x-axis, and he does not see the flashes occur simultaneously, but rather sees the flash at the 0cm end of the meterstick occur before the flash at the 100cm end. Chu is also in an inertial frame moving relative to both Ann and Bob along the common x-axis. Which of the following is a combination of observations that is not possible for Chu?
a.Chu sees Ann’s meterstick longer than Bob’s, and sees the flash at the 0cm end before the flash at the 100cm end.
b.Chu sees Ann’s meterstick longer than Bob’s, and sees the flash at the 100cm end before the flash at the 0cm end.
c.Chu sees Ann’s meterstick shorter than Bob’s, and sees the flash at the 0cm end before the flash at the 100cm end.
d.Chu sees Ann’s meterstick shorter than Bob’s, and sees the flash at the 100cm end before the flash at the 0cm end.
e.All of these observations can occur if Chu happens to be moving in the correct direction at the appropriate speed.
******* please when you choose the multiple choice please write a good explanation why you choose it. Please only answer questions 100% correctly and write very clear for me to undertsand. thank you
