The speed of sound depends on the elasticity and density of the medium through which it is traveling. In general, sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.
The speed of sound refers to the distance travelled per unit time by a sound wave as it moves. At 68º F its speed in air is about 343 meters per second, or 767 miles per hour or a kilometer in 2.9 seconds. There are two big factors to be considered: first one is temperature and the material the sound is traveling through, so the last option is the right answer.
Answer:Movement makes dolphins stress which can make your insusceptible framework more vulnerable and the flare-up will spread to different dolphins and conceivably other species.
