A large goose lands in a lake and bobs up and down for a short time. A fisherman notices that the first wave crest created by the goose reaches the shore 7.8 s after the goose first contacts the water. The distance between two wave crests is 90 cm, and in 2.2 s he sees four wave crests hit the shore. Determine how far from the shore the goose landed. Note: My calculations give me 12.76 but it is incorrect

A person stands at a point 380 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

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

A  progressive wave travelling in the x-direction is represented by the following equation: ?=?sin(??−??)y=Asin⁡(Bt−Cx).   Given that parameters ?A, ?B and ?C are given in SI units calculate the velocity of the wave for ?=50A=50 , ?=B= 2058 and ?=C= 30.

A fisherman notices that his boat is moving up and down periodically, owing to waves on the surface of the water. It takes 2.6 s for the boat to travel from its highest point to its lowest, a total distance of 0.53 m. The fisherman sees that the wave crests are spaced 4.8 m apart. How fast are the waves traveling? (Give your answer in m/s.)

Earthquakes generate sound waves inside Earth. Unlike a gas, Earth can experience both transverse (S) and longitudinal (P) sound waves. Typically, the speed of S waves is about 4.79 km/s, and that of P waves 7.51 km/s. A seismograph records P and S waves from an earthquake. The first P waves arrive 3.52 min before the first S waves. If the waves travel in a straight line, how far away does the earthquake occur? Number i Units

Earthquakes generate sound waves inside the earth. Unlike a gas, the earth can experience both transverse (S) and longitudinal (P) sound waves. Typically the speed of S wave is about 8.0 km/s, and that of P wave is 4.0 km/s. A seismograph records P and S waves from an earthquake. The first P wave arrives 4 min before the first S wave. Assuming the waves travel in straight line, at what distance does the earthquake occur ?

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 949 km and traveled a distance of 193 m in 11.52 h. What was the speed (in m/s) of the wave? For reference, the speed of a 747 jetliner is about 415 m/s. No need to include the unit. Write your answer in scientific notation. (1.11e+1) Add your answer

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?

An ultrasonic flow meter for measuring flow rate in a square channel uses two transducers that are placed at x = 1.35 m (Transducer 1) and x = 1.75 m (Transducer 2). x is measured along the length of the channel. The width of the channel is 0.3 m. The speed of sound in blood is 1500 m/s and the flow rate is 1.2 m3/s. Find the transit time (in μs) of the wave from Transducer 1 to 2 and the transit time (in μs) of the wave from Transducer 2 to 1.
