Answer:

15. The velocity of a sound wave is affected by two properties of matter: the elastic properties and density.

16. The greater the density of a medium, the slower the speed of sound. This observation is analogous to the fact that the frequency of a simple harmonic motion is inversely proportional to m, the mass of the oscillating object.

17. Temp °C 0 m/s2 m/s

50 360.51 361.62

18. Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly. The speed of sound in room temperature air is 346 meters per second. ... The speed of sound is also affected by other factors such as humidity and air pressure.
