Awoman can row a boat at 5.60 km/h in still water. (a) if she is crossing a river where the current is 2.80 km/h, in what direction must her boat be headed if she wants to reach a point directly opposite her starting point? express your answer as an angle with respect to the line perpendicular to the river, positive if down the river. (b) if the river is 5.60 km wide, how long will she take to cross the river? (c) suppose that instead of crossing the river she rows 2.80 km down the river and then back to her starting point. how long will she take? (d) how long will she take to row 2.80 km up the river and then back to her starting point? (e) in what direction should she head the boat if she wants to cross in the shortest possible time, and (f) what is that time?

Which of these statements best explains how the hydrosphere interacts with the atmosphere to affect global climate? mountains block rain clouds and cause changes in global rainfall and evaporation. humans burn fossil fuels to produce greenhouse gases which cause global warming. humans cut down trees which affects the amount of oxygen in different parts of the globe. greenhouse gases, like carbon dioxide, dissolve in oceans and prevent global warming.
