hunter is standing on flat ground between two vertical cliffs that are directly opposite one another. He is closer to one cliff than to the other. He fires a gun and, after a while, hears three echoes. The second echo arrives 1.6 s after the first, and the third echo arrives 1.1 s after the second. Assuming that the speed of sound is 343 m/s and that there are no reflections of sound from the ground, find the distance between the cliffs

A Girl Scout is taking a 12.00-km hike to earn a merit badge. While on the hike, she sees a cliff some distance away. She wishes to estimate the time required to walk to the cliff. She knows that the speed of sound is approximately 343 meters per second. She yells and finds that the echo returns after approximately 2.2 seconds. If she can hike 1.00 km in 7.3 minutes, how long would it take her to reach the cliff? At minutes

Tsunamis are fast-moving waves often generated by underwater earthquakes. In the deep ocean, their amplitude is barely noticeable, but upon reaching shore, they can rise up to the astonishing height of a six-story building. One tsunami, generated off the Aleutian Islands in Alaska, had a wavelength of 797 km and traveled a distance of 350 m in 14.39 h. What was the speed (in m/s) of the wave? For reference, the speed of a 747 jetliner is about 457 m/s. No need to include the unit. Write your answer in scientific notation. (1.11e+1)

The instrument known as the clarinet has a length of 42 cm, and is open at one end and closed at the other. The speed of sound in air is 343 m/s. What is the lowest frequency that can be sounded on the clarinet (i.e. the fundamental, or first harmonic). Group of answer choices 408 hz 51 hz 204 hz 816 hz 102 hz
