Awoman is standing in the ocean, and she notices that after a wave crest passes, five more crests pass in a time of 50.0 s. the distance between two successive crests is 32 m. determine, if possible, the wave's
(a) period.
(b) frequency.
(c) wavelength.
(d) speed.
(e) amplitude.
if it is not possible to determine any of these quantities, then so state.

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value

Ahair dryer is basically a duct in which a few layers of electric resistors are placed. a small fan pulls the air in and forces it through the resistors where it is heated. air enters a 1200 w hair dryer at 100 kpa and 22°c and leaves at 47°c. the cross-sectional area of the hair dryer at the exit is 60 cm2. neglecting the power consumed by the fan and the heat losses through the walls of the hair dryer, determine (a) the volume flow rate of air at the inlet and (b) the velocity of the air at the exit.
