While on vacation, Paul is staying in a hotel room with a balcony 18.0 m above the ground that is overlooking the ocean. He is curious as to how far he could throw a
rock before it hits the water. Recognizing that it would be unsafe to actually throw
the rock, he decides to work out the answer mathematically. He knows that he can
throw the rock horizontally at a speed of 30.0 m/s. How far from the hotel will the
rock be when it hits the water?

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.
