let us consider two inertial frames S and S'. The frame S' moves along the common positive direction of the x and x' . Two events A and B occur at the origin of S with timer interval of 2 sec, I.e. xa=xB=0 and Delta t_AB=tA-tB=2s. the time interval Delta t'_AB measured in S' is 3 s. Now let us consider two events C and D occurring at the origin S'. if the time interval Delta t'_CD measured in S' is 3s, what is the time interval Delta t_CD measured in S?

In c= 1 units, find the relative speed between two frames. to find speed in this unit, Divide by c.

Consider two events, A and B. In an inertial reference frame S, event A occurs at a time deltaT after event B, and event A occurs as positive x=0 and event B at x=L. From another reference frame S', it was observed that events A and B occur simultaneously. Given this information, what is the relative velocity of S' to S? Express answer in terms of the speed of light c, and the parameters given in the problem. (If you...

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...

What is the velocity of S2 as measured by observers in S1? 2. A meter stick at rest in S3 is tilted at an angle of θ3 = 30◦ to the y axis.

QUESTION 2 1.   Two people in different inertial reference frames are observing a ball as it moves through the air. One person claims to observe the ball to go straight up and then straight down. The other person claims to observe the ball to move in a parabolic path. What can we say about these two claims? a.   These two claims are mutually incompatible. The ball follows only a single path. Either it goes in a straight line up and...

Let us consider strategic risk. Look at the matrix and identify the two parameters that determine strategic risk. These two parameters are about the threat of opportunistic behavior from third-parties from which a company sources services. They do not necessarily distinguish between offshore and onshore providers. This observation leads us to a question: Now think of the measures that a company can adopt to mitigate strategic risk. Are some of those measures weakened by (or are costlier to implement) in...
