A ball is thrown straight up from the ground with an initial velocity of 39.8 m/s; at the same instant, a ball is dropped from the roof of a building 18.1 m high. After how long will the balls be at the same height? The acceleration of gravity is 10 m/s/s

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.
