Answer:

Yes there would still be a source of carbon dioxide in the water.

Explanation:

"Carbon Dioxide is present in water in the form of a dissolved gas.Surface waters normally contain less than 10 ppm free carbon dioxide, while some ground waters may easily exceed that concentration. Carbon dioxide is readily soluble in water. Over the ordinary temperature range (0-30 C) the solubility is about 200 times that of oxygen. Calcium and magnesium combine with carbon dioxide to form carbonates and bicarbonates.

Aquatic plant life depends upon carbon dioxide and bicarbonates in water for growth. Microscopic plant life suspended in the water, phytoplankton, as well as large rooted plants, utilize carbon dioxide in the photosynthesis of plant materials; starches, sugars, oils, proteins. The carbon in all these materials comes from the carbon dioxide in water.

When the oxygen concentration in waters containing organic matter is reduced, the carbon dioxide concentration rises. The rise in carbon dioxide makes it more difficult for fish to use the limited amount of oxygen present. To take on fresh oxygen, fish must first discharge the carbon dioxide in their blood streams and this is a much slower process when there are high concentration of carbon dioxide in the water itself."

Un objeto posee una energía cinética de 300J, este mismo se ubica a 4m de altura y su masa corresponde a 10Kg. ¿Cuál es su energ
Arturiano [62]

Answer: 692 J

Explanation:

La energía mecánica es la energía que se utiliza para realizar un trabajo determinado y se calcula con la suma de la energía cinética y la energía potencial de un objeto. En otras palabras, describe la energía de un objeto debido a su movimiento, posición, o ambos.

<u>La energía cinética es el trabajo necesario para acelerar un cuerpo desde el reposo hasta su velocidad final</u>. Entonces, es la energía que posee un cuerpo debido a su movimiento. Cuando gana energía durante la aceleración, el cuerpo mantiene la energía cinética a menos que su velocidad cambie, y el cuerpo realiza la misma cantidad de trabajo al desacelerar desde su velocidad actual hasta un estado de reposo. Por otro lado, <u>la energía potencial es la energía que posee un objeto debido a su posición con respecto a otros objetos.</u> Los tipos más comunes de energía potencial incluyen a la energía potencial gravitacional de un objeto que depende de su distancia al centro de masa de otro objeto (La Tierra), la energía potencial elástica de un muelle o resorte extendido y la energía potencial eléctrica de una carga en un campo eléctrico.

La unidad de energía en el Sistema Internacional de Unidades (SI) es el julio, que tiene el símbolo J.

La energía mecánica se calcula de la siguiente manera (tener en cuenta que la aceleración de la gravedad es un dato tabulado de 9,8m/s^2):

Energía mecánica = Energía cinética + Energía potencial

Energía mecánica = (1/2 * masa * velocidad^2) + (masa * gravedad * altura)

Energía mecánica = 300 J + (10kg * 9,8m/s^2 * 4m)

Energía mecánica  = 300 J + 392 J = 692 J

SVEN [57.7K]
A and B can be eliminated.<span> Buoyancy has to do with things floating on water and there's no heat involved with this experiment, so those two answers are wrong.

We're left with C and D. There is no surface tension involved, so the answer would be letter D - capillary action. Capillary action is what happens when water is forced up the walls of a vessel. Capillary action caused the celery to turn blue.

Answer: D

Hope that helps. -UF aka Nadia</span>
