An enormous thunderstorm covers Dallas-Ft. Worth. Your best friend Clark is a storm chaser and heads to the center of the storm to take some readings while you stay dry at home. While Clark is at the center of the storm, he sees and hears lightning strike a tree that is 185 m from where he is standing. You are 134 km from the tree. How long does it take for the sound to reach Clark? Assume the speed of sound is 343 m/s. How long does it take for the light to reach you?

A bat flying in a cave emits a sound and receives its echo 0.06 s later. Find the distance to the wall of the cave. (hint: the speed of sound, v = 343 m/s)

There was an accident and NASA engineers are trying to sort out where two of their Mars Rovers, Tango and Foxtrot, have landed. The engineers know that landing site A is much hotter than landing site B. Unfortunately, the only working sensors on Tango and Foxtrot measure the speed of sound. If Tango measures the speed of sound at it's landing site as 240 m/s, while Foxtrot measures speed of sound as 258 m/s at it's landing site, where has each rover landed?

Sound Caused by an explosion on the ocean's surface travels vertically downward to an underwater mountain and it is refelceted back to a microphone at the surface.  if it takes 11.6 seconds to occur and sound travels at 1450 m/s in water, what is the depth to this mountain?

A source of sound of frequency 1200 Hz is moving away from a listener at speed v. The listener is at rest and hears a frequency of 1150 Hz. Given that the speed of sound is 343 m/s, what the value of v? 15 m/s 20 m/s 25 m/s 30 m/s 35 m/s

An explosion occurs at the end of a pier. The sound reaches the other end of the pier by traveling through three media: air, fresh water, and a slender metal handrail. The speeds of sound in air, water, and the handrail are 347, 1460, and 5320 m/s, respectively. The sound travels a distance of 136 m in each medium. (a) After the first sound arrives, how much later does the second sound arrive? (b) After the first sound arrives, how much later does the third sound arrive?

The figure shows a series of sound waves leaving a moving source. B E с Rank the locations by frequency heard by a stationary listener at each letter location. lowest D and E V E highest C

An organ pipe that is 1.75 m long and open at both ends produces sound of frequency 303 Hz when resonating in its second overtone. What is the speed of sound in the room? m/s

A blood-flow meter emits a 1.9-MHz ultrasound pulse to measure the speed of blood moving directly away from the meter. The meter’s sensor detects the pulse reflected back from the blood at a frequency 27 Hz lower than the emitted frequency. Take the speed of sound in the tissues to be 1475 m/s. At what speed, in centimeters per second, is the blood moving?

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.
