You performed an experiment in which you measured the amount of water leaking through differentiations types of roofs. for one roof, you measured a volume of 3.4 gallons. what is the measurement in si units? 1 gal = 3.78 l

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?
