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?
Storms in the South Pacific can create waves that travel all the way to the California coast, which are 12,000 km away. How long does it take them if they travel at 15.4 m/s? __________ days
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...
Dungeness crab can be found along the northeastern Pacific coast, from California to Alaska, and are an important commercial commodity in this region. Santiago finds the harvest of Dungeness crabs for a SRS of 35 years. It is known that σ = 5.10 million pounds. Santiago's sample has a mean of x̅ = 9.05 million pounds. Use this information to construct a 95% confidence interval. (This problem inspired by data from the Quantitative Environmental Learning Project at http://www.seattlecentral.edu/qelp/sets/062/062.html) a. State the...
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...
1. The intensity of a particular earthquake wave is measured to be 1.60 x 106 W/m2 at a distance of 40.0 km from the source. What was the intensity when it passed a point only 1.00 km from the source? Assume that earthquake waves travel uniformly in all directions W/m2 2. The team monitoring a space probe exploring the outer solar system finds that radio transmissions from the probe take 2.10 hours to reach earth. How distant (in meters) is...
1 of 2) Calculate the speed, C, (in meters per second) of a tsunami with a wavelength of 180,000 meters (180 kilometers or112 miles) and period of 15 minutes traveling over the Pacific (which has an average depth of 4000 meters (4 kilometers or 2.5 miles). Round up your answer so that there is no decimal. Note that the answer is not 200 m/s as it is incorrect 2 of 2) Using the speed of the tsunami that you calculated...
A bubble forms on the ocean floor far away from the coast. Assume the density of the salt water is 1.05 g/cm3, and that the ocean is 0.600 km deep at this point. The pressure in the bubble is equal to the pressure in the surrounding water. a) What is the absolute pressure (in Pa) in the water at this depth? Assume that the air above the Ocean is at a pressure of 1.013 x 105 Pa. Be careful with...

Alpine-Himalayan Ocean Paoiño Ocean Ocean Deep eartho EXERCISE 16.2 Locating Earthquake Epicenters Name: Course Section: Date: This exercise leads you through the reasoning used to calculate the distance from a seismic station to epicenter. But instead of two different seismic waves, let's see first how this works with two cars that start along a road at exactly the same time (see the figure on the next page). Both use cruise control set at 1 mile per minute (60 miles per...
