Let two events occur at equal distances from an observer (O). The observer claims that two events will be simultaneous if light emitted from each event will reach me at the same time. Show that (maybe by drawing a picture) an observer (O') moving with respect to O will observe that these two events are not simultaneous. If two signals (say, from points A and B) reach observer O' simultaneously, what is their time sequence, as measured by O?

Two events are observed in a frame of reference S to occur at the same space point, with the second event occurring after a time of 1.70 s . In a second frame S' moving relative to S, the second event is observed to occur after a time of 2.25 s . What is the difference between the positions of the two events as measured in S'?

In an inertial frame two events occur simultaneously at a distance of 3 m apart. In a frame moving with respect to the laboratory frame, one event occurs later than the other by 10s. By what spatial distance are the two events separated in the moving frame? Solve this problem in two ways: first by finding the Lorentz boost that connects the two frames and second by making use of the invariance of the spacetime distance between the two events.

Two stars z and p, are exactly in the opposite directions from the Earth. The distance to 'z' from earth is 80 light-years. The distance to 'p' is 90 light-years. Zerah takes off in the direction of z, at a speed of 0.8 c, while Perez takes off in the direction of p at the speed 0.9c. (distance between two stars in earth frame = 170c*y) (time to each star in earth frame = 100 years, simultaneous events in earth's...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
