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'?

Amachinist needs to remove a tight fitting pin of material a from a hole in a block made of material b. the machinist heats both the pin and the block to the same high temperature and removes the pin easily. what statement relates the coefficient of thermal expansion of material a to that of material b? a) the situation is not possible, heating block b will shrink the hole in the material as the material expands with increasing temperatureb) material b has the same coefficient of expansion as does material ac) material b has a negative coefficient of expansion and a has a positive coefficient of expansiond) material a has a greater coefficient of expansion than does material be) material b has a greate
