- A person lying on an air mattress in the ocean rises and falls through one complete cycle every five seconds. The crests of the wave causing the motion are 27.4 m apart. Determine (a) the frequency and (b) the speed of the wave. (a) Number (b) Number i Units UnitsTsunamis 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)A wave has a speed of 20 m/s and a wavelength of 200 m. Find its frequency and period?
- 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.)Extremely strong waves along ocean waters, sometimes are of 20 meters in each of height and width!! Assuming that such a wave travels at speeds of 8.0 m/s, determine the frequency and the period of the wave. 0.23 Hz, 4.35 s O 0.40 Hz, 2.5 s 0.45 Hz, 2.22 s O 0.17 Hz, 5.88 s
- 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.Two waves, of the same wavelength are travelling in opposite directions. One wave has an amplitude of 10 cm, while the other wave has an amplitude of 5 cm. What is the magnitude of the amplitude of the resulting wave when the waves are constructively interfering? Question 5 options: 5 cm 20 cm 15 cm 10 cmA water skier is being pulled by a boat. As she approaches a wave that is angled at 19.0° she reaches a constant speed of 19.0 m/s. She launches off the first wave and lands on a second wave at the same height. How long was she in the air? 3.88 s 1.26 s 0.631 s 3.67 s
