- A boat produces water waves as it sails along a river. You notice that 10 waves hit the bank in 4.8 seconds. If distance between successive wave crests is 3.8 centimeters, how far would these waves travel in 35 seconds. Express your answer in centimeters to at least 3 significant figures.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 sA 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 boat produces water waves as it sails along a river. You notice that 13 waves hit the bank in 5.4 seconds. If distance between successive wave crests is 3.9 centimeters, how far would these waves travel in 31 seconds. Express your answer in centimeters to at least 3 significant figures.
- You want to create a standing sound wave in its 2nd overtone. Your smartphone can generate any frequency you want. The only tube you have is 1.68m long. You can either block one end or not; it’s up to you. What frequency should you use? Draw the representation of the standing wave.Two progressive waves yj = A sin( 4 x - ot) and y2 = A sin( 2" x – ot – 5) travel in the same direction. Calculate the velocity of the wave produced as a result of interference of these two waves. Take A = 5 cm, 1 =8.7 m and w =12.7 rad/s (radian per second). Give your answer in Sl units.Waves on a swimming pool propagate at 0.703 m/s. You splash the water at one end of the pool and observe the wave go to the opposite end, reflect, and return in 41.7 s. How far away is the other end?
