(a) How much time elapses before the geologist hears the sound from the eruption? (Assume the air temperature is 20°C.) (b) How much time does it take the seismic waves produced by the eruption to reach the geologist's camp, assuming the waves travel through granite as sound waves do? (Assume the granite temperature is 20°C.)
