B southeast Now assume that the insect, instead of floating on the surface, is resting on a leaf above the water surface at a horizontal distance 0.600 m away from the fish. The groove forms a long, narrow tube when the fish places its tongue against it and propels drops of water along the tube by compressing its gill covers. c 8s C. The energy used while runner is greater, the power while running is greater. For all parts, assume that the "island" refers to the point at a distance D from the point at which the package is released, as shown in the figure.
