In the deep ocean their amplitude is barely noticable, 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 669 km and traveled a distance of 3500 km in 4.14 h. (a) what was the speed (in m/s) of the wave? for reference, the speed of a 747 jetliner is about 250 m/s. find the wave's (b) frequency and (c) period.

In what direction does the medium move relative to the direction of the wave? explain.

During spring semester at mit, residents of the parallel buildings of the east campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. a balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. assume that the stretching of the hose obeys hooke's law with a spring constant of 89.0 n/m. if the hose is stretched by 5.80 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length? unitst 3 number-1497 the tolerance is +/-5% open show work click if you would like to show work for this question:
