Question 6 (3 points) An earthquake emits both S-waves and P-waves which travel at different speeds...
002 10.0 points Earthquakes produce two kinds of seismic waves: he longitudinal primary waves (called P waves) and the transverse secondary waves (called S waves). Both S waves and P waves travel through Earth's crust and mantle, but at different speeds; the P waves are always faster than the S waves, but their exact speeds depend on depth and location. For the pur- pose of this exercise, we assume the P wave's speed to be 8380 m/s while the S...
When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, or P, wave has a speed of about 8.0 km/s and the secondary, or S, wave has a speed of about 4.5 km/s. A seismograph, located some distance away, records the arrival of the P wave and then, 117 s later, records the arrival of the S wave. Assuming that the waves travel in a straight line, how far (in terms of...
An earthquake 55 km from a city produces P and S waves that travel outwards at 5000 and 3000 m/s, respectively.Part AOnce city residents feel the shaking of P wave, how much time do they have before the S wave arrives?
2. (1) A pendulum clock makes use of the fact that the period of a pendulum is consistent and can be predicted relatively easy. What should the length of a pendulum be if the desired frequency of oscillation is. 3. (1) Near the shore, Tsunamis travel at a speed of 30 mph and the distance between crests is about 6.5 miles. What is the frequency of such a wave? Give your answer in units of Hz. When one crest hits...
6. (1 point) 6. From the Oliver room, you are detecting seismic waves on your seismograph. At 12:00, you detect a longitudinal P wave, which travels at 8000 A 12: 01, you detect a transverse S wave, which travels through the earth slower at a speed of 4000 . Assuming that the waves travel in straight lines, how far from you was the earthquake? _(include units)
Earthquakes generate sound waves inside Earth. Unlike a gas, Earth can experience both transverse (S) and longitudinal (P) sound waves. Typically, the speed of S waves is about 4.5 km/s, and that of P waves 8.0 km/s. A seismo- graph records P and S waves from an earthquake. The first P waves arrive 3.0 min before the first S waves. If the waves travel in a straight line, how far away does the earthquake occur?
An earthquake generates three kinds of waves: surface waves (L-waves), which are the slowest and weakest, shear (S) waves, which are transverse waves and earn- most of the energy, and pressure (P) waves, which are longitudinal waves and are the fastest. People do not generally feel the P waves, but animals seem to be sensitive to them. Take the density of the material through which these waves travel to be 2.0 times 10^3 kg/m^3, the Young's modulus to be 9.8 times 10^10 N/m^2,...
A seismographic station receives S and P waves from an earthquake, separated in time by 16.2 s. Assume the waves have traveled over the same path at speeds of 4.50 km/s and 8.20 km/s. Find the distance from the seismograph to the focus of the quake. km
3. Earthquake warning system A typical earthquake produces two types of seismic waves. P ("primary" seismic waves are longitudinal waves that move through the earth's upper crust with speed anywhere from 3 km/s to 5 km/s (the exact speed depends on the local composition of the earth's crust). S ("secondary") waves are transverse waves that move slower than P waves. The S-wave speed is typically about 60% less than the P-wave speed in any given material. The map below shows...
QUESTION 2 Earthquakes produce several types of shock waves, two of which are called S and P waves. P waves travel at about 6.5 km/s, and S waves travel at about 3.5 km/s. The delay in arrival times between P waves and S waves provides from the measurement station. If a station records a delay of 33 s, how far from the station was the earthquake (ín kilometers? Use two significant figures in your answer. information about how far away...
