[B] Earthquakes generate two sorts of waves in rock, shear or 5 waves which travel at about 4.5 km/s and pressure or P waves traveling at about 8 km/s. (1) After one such quake, a seismograph station picks up the S wave 3.0 minutes after the P wave. How far away was the source, or epicenter, of the earthquake? | (2) When a quake is detected, a steady 250 Hz alarm sounds in the hallway of a facility to alert the person on watch. The alarm is also sent to the cell phones of the staff on duty which emit the same 250 Hz tone. One of the staff responding to the alert runs down the hall, approaching the hallway speaker. She notices a 2 Hz variation in the loudness of the 250 Hz tone as she runs with her phone. What frequency is she hearing from the speaker? From your answer, how fast was she running, if the speed of sound is 344 m/s? A wave traveling through granite comes to a boundary with sandstone.
