A physicist attempts to use Newton's laws of motion to predict the behavior of a molecule of water, but the laws fail to give accurate predictions. What is the most likely reason? A) Liquids do not follow the laws of motion.

B) The molecule is small enough so that quantum effects are important.

C) Newton’s laws apply to atoms, but not to molecules.

D) The molecule was likely traveling at a near-light speed.

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
