16.7 Which of the above three variables do you suppose most likely explains why the
largest waves occur at sea, rather than on lakes?
16.9 On Figure 16.6, measure the distance between the still-water level and wave base.
Double that value and compare it with wavelength. How do the two compare?
16.15 What does the simultaneous decrease in wavelength and increase in wave height
have to do with conservation of energy? Hint: A water particle within a wave crest has
both kinetic energy (energy of motion) and potential energy (energy of elevation).
16.21 In the Sydney 2000 Olympics, Americans Gary Hall, Jr. and Anthony Ervin tied
(yes, tied!) in the 50 m freestyle event. Their time: 21.98 seconds. Question: could Gary
and Anthony make it to shore swimming against a rip current moving at the rate of
16.28 In Figure 16.27, in what direction does the longshore current appear to be moving
northwestward or southeastward?
16.30 (A) Would a groin have been advisable here? Why or why not? (B) How about an
offshore breakwater? Why or why not?
16.32 When air temperatures in Florida dip slightly below freezing thereby threatening
an orange crop owners spray their trees with water in an effort to raise the
temperature of the trees a few degrees. Explain the reasoning behind this curious
16.34 It doesnt happen in the real world, but imagine a current of air or water flowing
exactly along the equator (or along any other line of latitude). What do you suppose
would be the Coriolis effect, if any?
16.36 So why the familiar eye in the center of a hurricane the volume of air that is
practically devoid of wind and rain? Hint: No doubt you have heard of this slinging kind
of force.
16.37 Quite simply, why dont hurricanes develop over land?
