The table below shows the speed of sound in water at different temperatures and salinities. Speed of Sound in Water at Different Temperatures and Salinities Temperature (°C) 0 10 20 30 Speed of sound in freshwater ( ms ) 1,403 1,447 1,481 1,507 Speed of sound in seawater ( ms ) 1,449 1,490 1,522 1,546 Which statement can be inferred about the speed of sound in freshwater and in seawater? (1 point) Responses At 80°C, the speed of sound in freshwater and seawater will be the same. At 80°C, the speed of sound in freshwater and seawater will be the same. The speed of sound increases as the density of water increases. The speed of sound increases as the density of water increases. Both temperature and salinity decrease the speed of sound in water. Both temperature and salinity decrease the speed of sound in water. The speed of sound increases as the salinity of water decreases.
The speed of sound increases as the density of water increases.
As a wave travels from one spring to another spring with a different mass, its wavelength decreases by 25%. Which statement describes the change in the speed of the wave?(1 point) Responses The speed decreases by 25% because speed and wavelength are directly proportional.
