hquakes produce seismic waves, which travel through Earth. Primary waves, or P-waves, are longitudinal. They can travel through both solids and liquids. Secondary waves, or S-waves, are transverse. They can travel through solids only. P-waves travel at approximately 8.0 km's, and 5- waves travel at approximately 4.5 km/s. Following an earthquake, vibrations are recorded at seismological stations around the world. 1. Calculate how long P-waves and S-waves take to travel from an earthquake to a seismological station that is 2.4X103 km away. Express your answers in minutes. 2. Why do you think that transverse waves are called secondary waves? 3. Explain how observing P-waves and 5-waves helps geophysicists analyze the structure of Earth's interior. 2) Research hearing loss in urban vs rural areas. What do you notice? How can you explain this difference? 3.) If a mass-spring system is hung vertically and set into vibration, why does the motion eventually stop? Sketch a graph that represents the amplitude of vibration over time. Annotate the graph(label the different components). 4.) Describe using examples and diagrams, the 3 types of waves. 5.) A force of 120. N [E30.0N] and 80.0 N [E405] act on an object. a Draw a vector diagram of the two original vectors b. Find the resultant of the two vectors. (Trig or Component method) C. What would a third force need to be to make the net force zero
