At rest, a car's horn sounds the note A (440 Hz). The horn is sounded while the car is moving down the street. A bicyclist moving in the same direction with one-seventh the car's speed hears a frequency of 416 Hz. (a) Is the cyclist ahead of or behind the car? ahead of the carbehind the car     (b) What is the speed of the car? (Assume the speed of sound in air is 343 m/s.)

A group of hikers hears an echo 3.40 s after shouting. How far away is the mountain that reflected the sound wave? (Assume the speed of sound is 342 m/s.)

There is a tube of length 1.0 m with one end closed. You clapped your hand at the mouth of the tube once. The echo of the clap came back after 6.0 milliseconds. What is the velocity of sound in the tube ? 330 m/s O 320 m/s 290 m/s O 170 m/s

At rest, a car's horn sounds the note A (440 Hz). The horn is sounded while the car is moving down the street. A bicyclist moving in the same direction with one-ninth the car's speed hears a frequency of 407 Hz. (a) Is the cyclist ahead of or behind the car? O ahead of the car O behind the car (b) What is the speed of the car? (Assume the speed of sound in air is 343 m/s.) m/s

A person stands at a point 348 m in front of the face of a sheer cliff. If the person shouts, how much time will elapse before an echo is heard? (Assume the speed of sound is 344 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 342, 1400, and 5140 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?

Two cars are heading straight towards each other with the same speed. the horn of one sounds at a frequency of 3000 Hz but is beard by the driver of the other car as 3400 Hz. If the speed of sound is 340 m/s, find the speed of each car.

During a thunderstorm, a 5.5 s difference between observing a lightening flash and hearing the resultant thunder.  How far away in km and mi was the lightening flash? (The speed of sound is 344 m/s)

At rest, a car's horn sounds the note A (440 Hz). The horn is sounded while the car is moving down the street. A bicyclist moving in the same direction with one-seventh the car's speed hears a frequency of 421 Hz. (a) Is the cyclist ahead of or behind the car? ahead of the carbehind the car     (b) What is the speed of the car? (Assume the speed of sound in air is 343 m/s.) m/s

A group of hikers hears an echo 4.10 s after shouting. How far away is the mountain that reflected the sound wave? (Assume the speed of sound is 344 m/s.)
