En un tanque de agua se sumerge un diapasón que vibra con una frecuencia de 600Hz. Las ondas sonoras resultantes en el agua tienen una longitud de onda de 2,5m. ¿Cuál es la velocidad del sonido en el agua?

1500 ms-1

Explanation:

La velocidad de una onda se obtiene de;

Velocidad de onda = frecuencia * longitud de onda

Cuándo;

Frecuencia = 600 Hz

Longitud de onda = 2,5 m

Luego se deduce que la velocidad del sonido en el agua = 600 Hz * 2,5 m = 1500 ms-1

they float because they are less dense than the water itself

something denser than water, like a rock, will sink to the bottom

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
