Refer to the snapshot graph at time t = 0.0 s. One wave, with peak value of 2, is moving to the right with velocity 1.0 m/s. A second wave, with peak value of -2, is moving to the left with velocity -2.0 m/s. At a later time t = 6.0 s, what is the displacement y of the combined wave at x = 3.0 m? Snapshot graph 3 v = +1 m/s 2 -5 -1 0 5 10 15 x (m) v = -2 m/s MID W NA 17.0 kg large object is suspended from a crane using a rope (H = 0.006 kg/m). The rope is plucked, sending a wave down the rope. Calculate the speed of the wave (in m/s) as it moves along the rope. Enter the numerical part of your answer to the nearest integer. Your Answer: AnswerA string on a ukelele has a linear density of 1.04 x 104 kg/m, and has a tension of 74.79 N. Calculate the wave speed (in m/s) when this string is plucked. Enter the numerical part of your answer to zero decimal places.What happens to the string's vertical displacement when the waves meet? Briefly explain why?Australia 108 is a 319 m high tower in Melbourne. It has four water supply tanks located high in the building. Briefly explain why using water supply tanks is preferred over using water from the street-level water mains supply. Hint: In your answer, make sure that the reason is related to a physics principle covered in this unit
