Step by step
Solved in 3 steps
- The driver of a car traveling 24.0 m/s sounds his horn as he approaches an intersection. If the horn has a frequency of 655 Hz, what frequency does a pedestrian hear, if she is at rest at the intersection's crosswalk? Assume a sound speed of 343 m/s.The speed of sound in air is given as 340 m/s. What is the wave length of a 318 frequency wave?A bat flying in a cave emits a sound and receives its echo 0.09 s later. Find the distance to the wall of the cave. Express your answer to two significant figures and include the appropriate units.
- A bullet is fired and moves at a speed of 1342 mph. Assume the speed of sound is v = 340.00 m/s. What is the angle of the shock wave produced?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 346, 1400, and 5480 m/s, respectively. The sound travels a distance of 142 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? (a) Number i (b) Number i Units UnitsThe warning tag on a lawn mower states that it produces noise at a level of 99.0 dB. What is this in W/m2?
- A 2nd harmonic sound wave fills an empty glass jug 60 cm long. If it moves at 340 m/s, what is the frequency produced?During a thunderstorm, 3.1 s elapses between observing a lightning flash and hearing the resulting thunder. Approximately how far away in kilometers and miles was the lightning flash? (Assume the speed of sound is 344 m/s.) km miA group of hikers hears an echo 4.60 s after shouting. How far away is the mountain that reflected the sound wave? (Assume the speed of sound is 342 m/s.)
- Bats of the Vespertilionidae family detect the distance to an object by timing how long it takes for an emitted signal to reflect off the object and return. Typically they emit sound pulses 3.00 ms long and 70.0 ms apart while cruising. If an echo is heard 32.8 ms later (vsound = 331 m/s), how far away is the object? When an object is only 39.2 cm away, how long will it be before the echo is heard? When an object is only 39.2 cm away, the bat __________ able to detect the echo.A group of hikers hears an echo 3.00 s after shouting. How far away is the mountain that reflected the sound wave?A group of hikers hears an echo 1.30 s after shouting. How far away is the mountain that reflected the sound wave? (Assume the speed of sound is 348 m/s.)
