G 2) The deceleration of a body in water due to hydrodynamic drag is a function of the body’s velocity. Assume that the acceleration due to hydrodynamic drag for a boat is given by: a = −0.05v 2 m s 2 Where v is the boat’s velocity. If the boat is moving at 10 m/s when the engine is shut down, find the boat’s velocity 4 seconds after the engine is shut dow

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

Figure 9 on page 362 shows various motions of balls. the curved path followed by the yellow ball in b in picture b is result of a) inertia b) centripetal motion c) gravity and horizontal velocity d) linear motion
