1. An airfoil is the cross-sectional shape of a wing. The figure at right shows the streamlines around an airfoil. Explain why this airfoil experiences a net force that points up. 2. When bowhead whales (Balaena mysticetus) open their mouths to feed on plankton, water goes through the anterior opening (AO) of their mouths and across their baleen (which filters out the Coninglocal tubercle plankton for the whale to eat) before Anterior concurily passing through one of two posterior of tongue Lip - openings (PO), as shown in the figure below.' What is the pressure Rack of difference between the anterior and baleen plate's posterior openings, if the whale is Abductor musculature swimming horizontally at a typical within p speed of 1.11 m/s, seawater has a PO density of 1024 kg/m', the anterior Plicae (folds) around tongue opening has an area of 5.73 m', and Central funnow each posterior opening has an area Pleiryna of tongue of 1.57 m-?
