In a room that is 2.69 m high, a spring (unstrained length = 0.28 m) hangs from the ceiling. A board whose length is 2.22 m is attached to the free end of the spring. The board hangs straight down, so that its 2.22-m length is perpendicular to the floor. The weight of the boar...

A woman is standing in the ocean, and she notices that after a wave crest passes by, five more crests pass in a time of 68.0 s. The distance between two successive crests is 34.1 m. What is the wave's (a) period, (b) frequency, (c) wavelength, and (d) speed?
