Picnickers see a lightning flash and hear the resulting thunder 5 seconds later. The storm is traveling at a rate of 21 km/hr.Use 344 m/s for the speed of sound.(a) Roughly how far away is the storm in miles?Don't use this number for parts (b) thru (e)(b) How far away is the storm (hint: use 344 m/s...)?(c) How fast is the storm in m/s?(d) How long do the picnickers have before the storm arrives (sec)?(e) How long do the picnickers have before the storm arrives (min)?
A lightning bolt is observed and the resultant thunderclap is heard 5 seconds afterwards. Assuming the speed of sound in air is 340 m/s, how far away was the lightning bolt? Your answer should be in units of m but you should only submit the number for your answer.
An explosion occurs 34 km away. The time it takes for its sound to reach your ears, traveling at 340 m/s what?

- A student drops a water-filled balloon from the roof of the tallest building in town trying to hit her roommate on the ground (who is too quick). The first student ducks back but hears the water splash 4.021 s after dropping the balloon. If the speed of sound is 331 m/s, find the height of the building, neglecting air resistance.arrow_forward(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.)arrow_forwardIn 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?arrow_forward
- A lighting is observed, followed by thunder 2.55 seconds later. If speed of sound in air is 343 m/s, how many kilometers away did the lighting strike?arrow_forwardThe speed of sound at sea level is 340.29 m/s if lightning strikes 13.5 miles away, how long (in minutes) does it take for the sound of the thunder to reach you? (use the speed as a conversion factor.) The answer must be given in only one equation.arrow_forwardOn December 26, 2004, a great earthquake occurred off the coast of Sumatra and trig- gered immense waves (tsunami) that killed some 200, 000 people. Satellites observing these waves from space measured 800 km from one wave crest to the next and a period between waves of 1.0 hour. What was the speed of these waves in m/s and km/h? Does your answer help you understand why the waves caused such devastation?arrow_forward

Assume that sound traveled at 350.0 m/s during the storm.arrow_forwardAn echo is heard after 5 seconds of the production of sound which moves with a speed of 340 m/s. What is the distance of the mountain from the source of sound which produced the echo?arrow_forward
- An engineer drops a penny into a wishing well and measures the time for the sound or a splash to return a.

How many feet away was the lightning strike?arrow_forwardOn a day when the speed of sound is 344 m/s, Tom hollers and hears an echo 2.4 seconds later. How far away is the object that caused the echo?arrow_forward
