Rowan is walking in a shallow, clear bay, in still water just over her knees. when she looks down at her feet in the sand, she notes that they appear closer to her than usual. normally, when she tips her head forward to look at her feet, her feet are 1.60 m from her eyes. how far away do her feet appear when they are under 0.60 m of water?

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative
