The water in a river flows uniformly at a constant speed of 2.27 m/s between parallel banks 69.3 m apart. you are to deliver a package directly across the river, but you can swim only at 1.58 m/s. (a) if you choose to minimize the time you spend in the water, in what direction should you head? ° from the direction of the stream (b) how far downstream will you be carried? m (c) if you choose to minimize the distance downstream that the river carries you, in what direction should you head? ° from the direction of the stream (d) how far downstream will you be carried?

Scientist have use computer models to create a series of maps that show how susceptible coastal cities in island countries are to the sea rising at different levels. the map shows that a 1 meter rise would swap cities all along the us eastern seaboard. a 6-meter sea level rise with sub merge a large part of florida. thermal expansion has already raise the oceans 10 to 20 centimeters the most likely cause, directly and indirectly, for such a rise in sea level is
