Two points A and B on the surface of the Earth are at the same longitude and = 70.0° apart in latitude as shown in the figure below. Suppose an earthquake at point A creates a P wave that reaches point B by traveling straight through the body of the Earth at a constant speed of 7.40 km/s. The earthquake also radiates a Rayleigh wave that travels at 3.05 km/s. In addition to P and S waves, Rayleigh waves are a third type of seismic wave that travels along the surface of the Earth rather than through the bulk of the Earth. B Path of P wave 0 Path of Rayleigh wave i (a) Which of these two seismic waves arrives at B first? O the Rayleigh wave the longitudinal P wave (b) What is the time difference between the arrivals of these two waves at B? (The radius of the Earth is 6370 km.) 246 X Your response differs from the correct answer by more than 10%. Double check your calculations. S
