¿Que impacto tiene los diferentes tipos de centrales eléctricas en nuestro medio ambiente?​
Fofino [41]

Answer:

Sin los correspondientes controles y marcos regulatorios, las centrales eléctricas pueden tener efectos adversos sobre el medio ambiente y contaminar los ecosistemas naturales, representando un serio riesgo para la salud humana

Explanation:

Las centrales eléctricas representan un riesgo latente para el medio ambiente, con lo cual ellas deben estar bajo un estricto marco regulatorio y control por parte de las instituciones gubernamentales especializadas para tal fin. Por ejemplo, las centrales hidroeléctricas generan la inundación permanente de grandes áreas (incluso miles de hectáreas) con el objetivo de aumentar la capacidad de generación de energía eléctrica. Por otra parte, se cree que aproximadamente el 50% de la polución industrial se debe a la acción de centrales eléctricas convencionales, las cuales utilizan la combustión del carbón, el petróleo o el gas natural con el objetivo de generar energía eléctrica. Este tipo de centrales eléctricas producen dióxido de carbono (CO2), el principal gas de efecto invernadero y considerablemente deterioran la calidad del aire que respiramos mediante la liberación de partículas contaminantes, presentando efectos adversos tanto para la salud humana como para el medio ambiente. Finalmente, la instalación de centrales eléctricas a base de la energía nuclear no generan gases causantes del efecto invernadero, pero pueden representar un serio riesgo debido a la posibilidad de liberación de materiales radiactivos durante accidentes nucleares, los cuales son capaces de contaminar permanentemente el medio ambiente. En este punto, es importante aclarar que los riesgos de accidentes en centrales nucleares se ha reducido notablemente en las últimas décadas y, por lo tanto, este tipo de centrales eléctricas se consideran relativamente seguras.

Can you tell the difference between electromagnetic and mechanical waves?
mart [117]

Answer:

Electromagnetic waves can travel through a vacuum, that is an empty space, whereas mechanical waves cannot. They need a medium to travel such as water or air. Ripples in a pond are an example of mechanical waves whereas electromagnetic waves include light and radio signals, which can travel through the vacuum of space.
