Similar questions

(a) Seismographs measure the arrival times of earthquakes with a precision of 0.100 s. To get the distance to the epicenter of the quake, geologists compare the arrival times of S- and P-waves, which travel at different speeds. If S- and P-waves travel at 4.00 and 7.20 km/s, respectively, in the region considered, how precisely can the distance to the source of the earthquake be determined? (b) Seismic waves from underground detonations of nuclear bombs can be used to locate the test site and detect violations of test bans. Discuss whether your answer to (a) implies a serious limit to such detection. (Note also that the uncertainty is greater if there is an uncertainty in the propagation speeds of the S- and P-waves.)
In Bosnia, the ultimate test of a young nuns courage used to be to jump off a 400-year-old bridge (destroyed in 1993; rebuilt in 2004) into the River Neretva, 23 m below the bridge. (a) How long did the jump last? (b) How fan was the jumper traveling upon impact with the river? (c) If the speed of sound in air is 340 m/s, how long after the jumper took off did a spectator on the bridge hear the splash?
A dolphin in an aquatic show jumps straight up out of the water at a velocity of 13.0 m/s. (a) List the knowns in this problem. (b) How high does his body rise above the water? To solve this part, first note that the final velocity is now a known and identify its value. Then identity the unknown, and discuss how you chose the appropriate equation to solve for it. After choosing the equation, show your steps in solving for the unknown, checking units, and discuss whether the answer is reasonable. (c) How long is the dolphin in the air? Neglect any effects due to his size or orientation.
On February 15, 2013, a superbolide meteor (brighter than the Sun) entered Earth’s atmosphere over Chelyabinsk, Russia, and exploded at an altitude of 23.5 km. Eyewitnesses could feel the intense heat from the fireball, and the blast wave from the explosion blew out windows in buildings. The blast wave took approximately 2 minutes 30 seconds to reach ground level. (a) What was the average velocity of the blast wave? b) Compare this with the speed of sound, which is 343 m/s at sea level.
Rachel watches a thunderstorm from her window. She sees a flash of lightning bolt and begins counting the seconds until she hears a clap of thunder 10.0 ??????? later. Assume the speed of sound in air is 340 ?⁄? and the light was seen instantaneously. How far away was the lightning?
A large volcanic eruption triggers a tsunami. At a seismic station 350 km away, the instruments record that the time difference between the arrival of the tidal wave and the arrival of the sound of the explosion is 18.0 min. Assume the tsunami travels at 600 km/h. What is the ratio of the speed Utsunami of the tsunami to the speed Usound of the sound of the explosion? How much time t₁ after the explosion does it take for the first wave to reach the seismic station? How much time t2 after the explosion does it take for the second wave to reach the seismic station? Utsunami Usound t₁ = t₂ = = S S
Suppose you drop a rock into a dark well and, using precision equipment, you measure the time that elapses until the sound of the splash reaches you to be 2.5 seconds. Calculaté the well's depth to the surface of the water taking into 'account the time for sound to travel up the well. The speed of sound is 330 m/s in this well. What, if any, assumptions did you make in your calculation.
why F3 only * Sin30, althought there are also 2m and 2m length on the start.
Please solve and answer the problem correctly and also be sure to give the correct units. Thank you!!
A stone is dropped into a well and 4.5 seconds later the sound of the splash is heard. Then asecond stone is thrown downward into the well with an initial velocity Vo and the sound of thesplash is heard in 4 seconds. If the velocity of sound is constant at 1120 fps, determine the initialvelocity of the second stone.a. Identify the type of motion defined in the problem. b. Set up the equations of motion that is required to solve the problem. c. Solve for the unknown variables by substituting the given in the equations of motionthat has been set up previously.

Nuclear explosions cause a blast wave, a high-pressure shock wave generated by the heat from the fireball. These shock waves can travel in air at an average speed of 738 mph. (1 mile = 1609 meters). If a nuclear weapon in detonated in Pittsburgh, how far will the blast wave have traveled from the location of detonation 2.39 s after the explosion? (Give your answer in meters)
