Asteel wire of length 31.0 m and a copper wire of length 16.0 m, both with 1.00-mm diameters, are connected end to end and stretched to a tension of 134 n. during what time interval will a transverse wave travel the entire length of the two wires? (the density of steel and copper are 7860 and 8920 kg/m3, respectively.) .4 incorrect: your answer is incorrect.

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
