In some inertial frame s, two events occur at the same place but at 60m/e apart, where e is the speed of light. in another inertial frame s' the same two events occur 45 m apart in space. () (2 points) is the spacetime interval between these events timelile, lightlike or spacelile? (b) (2 points) what is the coordinate time. at', separating the two events in the s' frame? (e) (2 points) draw the spacetime diagrams for both frames, draw the world lines and mark the two (e) (2 points) how far in space has the frame s moved between events, as observed from s"? (d) 2 points what is the speed of the frame samen from s'?

An initially unpolarized light if intensity 500 w/m^2 passes through four polarizers. the transmission axis between adjacent polarizers is 45∘. what percentage of the initial intensity is transmitted by the system?

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i. e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i. e. include the distance traveled to the first encounter)
