Asound wave travels through water. what best describes the direction of the water particles? the water particles move perpendicular to the source of the sound wave. the water particles move in the same direction as the vibrating source of the sound wave. the water particles move in random patterns because the sound is diffracted in many directions. the water particles do not move because the sound wave does not have enough energy

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
