A woman is standing in the ocean, and she notices that after a wave crest passes, five more crests pass in a time of 54.0 s. The distance between two successive crests is 36 m. Determine, if possible, the following properties of the wave. (If not possible, enter NOT POSSIBLE.)

Consider an ordinary, helium-filled party balloon with a volume of 2.2 ft3. the lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon. using this fact, we can derive archimedes’ principle, namely that the upward force on the balloon is equal to the weight of the air displaced by the balloon. assuming that the balloon is at sea level, where the air density is 0.002377 slug/ft3, calculate the maximum weight that can be lifted by the balloon. note: the molecular weight of air is 28.8 and that of helium is 4.
