Awatermelon seed has the following coordinates: x = -7.3 m, y = 4.1 m, and z = 0 m. find its position vector as (a) a magnitude and (b) an angle relative to the positive direction of the x axis. if the seed is moved to the xyz coordinates (3.4 m, 0 m, 0 m), what is its displacement as (c) a magnitude and (d) an angle relative to the positive direction of the x axis? put the angles in the range (-180°, 180°].

Truck traveling west on the highway experiences an acceleration to the east. what could be the cause of this acceleration

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
