Couldn't going green stimulate our economy?

Antonette Shappy: Yes, I am. Are you proud that every word that comes out of McCainPalins mouth is a lie?

Libby Berkovitch: Actually, look at what the Clinton Administration did to the Community Reinvestment Act in 1995. One of the changes allowed FM&FM to only need 2.5% of capital to back their investments while other banks needed 10%. Once FM&FM took over half of the mortgage loans ($6 trillion), their risk increased. Nothing was done to stop the mortgage crisis even though Bush tried in 2001 and 2003 for the changes to be reversed and it was turned down. Then McCain tried for an intervention via regulation in 2006 and the Congress turned it down then too. The only things that happened from this is, one, Barney Frank and Chris Dodd became rich and, two, the American people got screwed....Show more

Rachell Meese: I happen to really LIKE Palin. As for McCain, his concession speech actually shows what type of person he truly is. I am sadden that he did not show this side of himself during the campaigning, it would have done him a lot of good.

Palin- while we all know now she needs more grooming for such high office, she showed the courage to take on a monumental task that few women would have stepped into them pumps.

Rena Pepe: Yes. Going green will stimulate the economy. One reason is because if we spend less money on all of these man made electronics we will save by using natural energy. One great example of that is the wind energy. Wind power creates more jobs, and it decreases the amount of money spent to power chemical and electrical plants. Also as you said solar energy. Obama did say that going green would stimulate the economy. I think he is right. In fact many companies are catching on. Also creating cars that run off of natural energy and more hybrid vehicles.

I think it is very unfair that people are blaming her for the lost. I think that the fact so many people voted for Obama was based on their desire for aggressive change.

what is global warming ?

Tillie Wynott: a lie pure and simple

Whitley Leopold: definition:Global Warming: Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate. A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. When scientists talk about the issue of climate change, their concern is about global warming caused by human activities...effects:Even a small increase in temperature over a long time can change the climate. When the climate changes, there may be big changes in the things that people depend on. These things include the level of the oceans and the places where we plant crops. They also include the air we breathe and the water we drink.What Might Happen? It is important to understand that scientists don't know for sure what climate change will bring. Some changes brought about by climate change will be good. If you live in a very cool clim! ate, warmer temperatures might be welcome. Days and nights could be more comfortable and people in the area may be able to grow different and better crops than they could before. But it is also true that changes in some places will not be very good at all.Human HealthClimate change may affect people's health both directly and indirectly. For example, heat stress and other heat related health problems are caused directly by very warm temperatures and high humidity. Untreated, heat stress can be a very serious medical problem. Scientists suspect that, in many places, climate change will increase the number of very hot days that occur during the year. More hot days increases the possibility of heat related health problems.Indirectly, ecological disturbances, air pollution, changes in food and water supplies, and coastal flooding are all examples of possible impacts that might affect human health.How people and nature adapt to climate change will determine how seriously it impa! cts human health. Some people and places are likely to be affe! cted more than others. Generally, poor people and poor countries are less likely to have the money and resources they need to cope with preventing and treating health problems. Very young children and the elderly adults will run the highest risks.Ecological SystemsClimate change may alter the world's habitats and ecosystems â€" all living things are included in and rely on these places. Many of these places depend on a delicate balance of rainfall, temperature, and soil type. A rapid change in climate could upset this balance and seriously endanger many living things.Most past climate changes occurred slowly, allowing plants and animals to adapt to the new environment or move somewhere else. However, if future climate changes occur as rapidly as some scientists predict, plants and animals may not be able to react quickly enough to survive. The ocean's ecosystems also could be affected for the same reasons.Sea Level RiseGlobal warming may make the sea level become higher. Wh! y? Well, warmer weather makes glaciers melt. A glacier is a large sheet of ice that moves very, very slowly. Some melting glaciers add more water to the ocean. Warmer temperatures also make water expand. When water expands in the ocean, it takes up more space and the level of the sea rises.Sea level may rise between several inches and as much as 3 feet during the next century. This will effect both natural systems and manmade structures along coastlines. Coastal flooding could cause saltwater to flow into areas where salt is harmful, threatening plants and animals in those areas. For example, an increase in the salt content of the Delaware and Chesapeake bays is thought to have decreased the number of oysters able to live in those waters.Oceanfront property would be affected by flooding, and beach erosion could leave structures even more vulnerable to storm waves. Whether we move back from the water or build barricades in the face of a rising sea, it could cost billions of ! dollars to adapt to such change. Coastal flooding also may reduce the q! uality of drinking water in coastal areas.Crops and Food SupplyGlobal warming may make the Earth warmer in cold places. People living in these places may have a chance to grow crops in new areas. But climate change also might bring droughts to other places where we grow crops. In some parts of the world, people may not have enough to eat because they cannot grow the food that they need....Show more

Hans Sachetti: what is global warming? Good question, go here and be enlightened.http://news.nationalgeographic.com/news/2007/02/07...

Cómo calcular el yardaje de concreto

Cómo calcular el yardaje de concreto

Antes de comenzar cualquier trabajo de colocación de concreto, es importante determinar el volumen correcto de concreto necesario para el trabajo. Una cantidad insuficiente de concreto puede causar que usted tenga que hacer una colocación de concreto en 2 pasos separados, lo cual creará una costura estructuralmente débil entre las 2 colocaciones. Demasiado, por otro lado, puede ser una pérdida de dinero. Afortunadamente, calcular el yardaje de concreto de un proyecto es usualmente una simple cuestión de calcular el volumen del espacio a ser derramado y luego agregar 5-10% a este número para ser conservador. Para las colocaciones básicas de concreto que requieren que el concreto se vierta en un área rectangular en 3-D, el cálculo del volumen se realiza con la ecuación b>longitud × anchura × altura/b>.

Convierta su cifra de volumen en peso, si! es necesario. El concreto mezclado en camiones se vende por volumen, pero las bolsas de mezcla de concreto se venden en establecimientos minoristas por peso. A menudo, la mezcla seca tendrá información en la bolsa indicando el peso o volumen «húmedo» que cada bolsa produce. El concreto pesa alrededor de 4000 libras por yarda cúbica (2400 kg por metro cúbico). Así que, si usted necesita 2 yardas cúbicas (1.53 metros cúbicos) de concreto, entonces usted necesita (2 * 4000) u 8000 libras, o (1.53 * 2400) o 3672 kg de concreto. Como se mencionó anteriormente, comprar más mezcla de concreto seca de la que se necesita es generalmente mucho más seguro que comprar menos mezcla de concreto de la que se necesita â€" la mezcla sin usar siempre se puede usar en el futuro.

Asegúrese de que el concreto que va a verter sea un prisma rectangular. Los contratistas han ideado un sistema rápido y sencillo para determinar la cantidad de yardas de concreto que se necesita ! para un vertido determinado. Este método no requiere el uso d! e ninguna ecuación de volumen â€" sin embargo, hay dos estipulaciones para su uso. En primer lugar, sólo funciona para prismas rectangulares (vertidos básicos en forma de caja). Este método es más fácil para vertidos relativamente poco profundos, pero es posible para todos los prismas rectangulares. Segundo, requiere que las medidas de longitud y ancho de su área de vertido sean en pies y que la medida de profundidad sea en pulgadas. Para convertir cualquiera de sus medidas a pies, utilice los factores de conversión que se indican a continuación:

Calcule el volumen de cada prisma. El volumen de un prisma rectangular se puede encontrar multiplicando su longitud por su anchura por su altura. Por ejemplo, en los siguientes pasos, imaginemos que estamos vertiendo una losa de 10 pies (3,05 m) de largo, 12 pies (3,66 m) de ancho y 4 pulgadas (10,16 cm) de profundidad.

Convierta todas las mediciones a las mismas unidades. La longitud y el ancho de nuestra losa! se dan en pies y metros, pero su altura se da en pulgadas y centímetros. Para que nuestra ecuación de volumen funcione, todas las medidas deben estar en las mismas unidades, por lo que debemos convertirlas. Ya que hay 12 pulgadas por pie, debemos dividir nuestro valor en pulgadas por 12 para obtener un valor para los pies. La losa es de 4/12 = 0,33 pies de profundidad.

Convierta el volumen en yardas cúbicas o metros cúbicos según sea necesario. El volumen de la losa arriba se expresa como 39.6 pies cúbicos, pero, desafortunadamente, el concreto se mide generalmente en yardas cúbicas. Hay 27 pies cúbicos en un yarda cúbica, así que, para convertir a yarda cúbica, podemos dividir por nuestro valor de pies cúbicos por 27. El volumen de la losa es de 39,6 / 27 = 1,47 yardas cúbicas. Alternativamente, ya que hay tres pies en un patio, puede dividir cada medida de pie individual por 3 para obtener los valores del patio y luego multiplicarlos para obtener la mi! sma respuesta.

Divida su proyecto de hormigón en diferentes pris! mas rectangulares. Comparado con otras formas 3-D, el volumen de un prisma rectangular es relativamente fácil de calcular, así que, si es posible, es mejor dividir todo el proyecto en uno o más prismas rectangulares. Por ejemplo, si su proyecto requiere que vierta una sola losa rectangular sobre el nivel del terreno, esa losa será su único prisma. Sin embargo, si necesita verter una losa junto con 4 paredes rectas, cada pared será su propio prisma, resultando en un total de 5 prismas.

Calcule el volumen de cualquier forma irregular. No todos los trabajos de hormigón se pueden dividir fácilmente en prismas rectangulares. Por ejemplo, si tiene una base extendida en su diseño de concreto, no puede aproximarse con precisión a su forma usando prismas rectangulares. Para encontrar el volumen de una forma irregular, primero encuentre el área de una sección transversal de la forma. Luego, multiplique ese área por la longitud del formulario. Por ejemplo, si una ba! se extendida tiene 3 yardas (2,74 m) de largo y un área de sección transversal de 0,25 yardas cuadradas (0,21 metros cuadrados), entonces el volumen es de 3 × 0,25 = 0,75 yardas cúbicas (o 2,74 × 0,21 = 0,58 metros cúbicos).

Familiarícese con la forma en que se mide el volumen de concreto. El volumen del concreto (la cantidad de espacio físico que ocupa) se mide típicamente en yardas cúbicas (yardas) o metros cúbicos (m). Un yarda cúbica es un cubo tridimensional de 3 pies de largo en cada dimensión, mientras que un metro cúbico es un cubo de 1 metro de largo en cada dimensión.

Halla el volumen del prisma usando la fórmula: Volumen = Longitud * Anchura * Altura. Multiplica las 3 dimensiones para llegar al volumen del prisma. En nuestro ejemplo, el volumen de la losa es de 10 pies × 12 pies × 0,33 pies = 39,6 pies cúbicos.

Determinar manualmente los coeficientes impares. Si el espesor de su concreto no coincide con ninguno de los ejemplos! anteriores, puede calcularlo rápidamente dividiendo 324 por el espeso! r de su proyecto de concreto (en pulgadas). Luego, divida los pies cuadrados por la respuesta para encontrar el área de yardas de su proyecto.

Encuentre volúmenes adicionales de prismas como en el ejemplo anterior. Si tiene más de un prisma en su concreto, calcule el volumen de cada uno individualmente usando el método anterior. Finalmente, sume todos los volúmenes para llegar al volumen total de su proyecto. Tenga cuidado de que ninguno de sus prismas se superponga, o terminará contando algo del concreto dos veces, lo que puede llevarle a comprar más de lo que necesita.

Encuentre los pies cuadrados del área que está vertiendo. Los pies cuadrados (escritos «sq. ft» o pies) son una medida del área bidimensional que se usa típicamente para describir el espacio en el piso. Para determinar los pies cuadrados de su trabajo de concreto, simplemente multiplique el largo y ancho del área que está vertiendo sin tener en cuenta su profundidad.

Divida ! sus pies cuadrados por un coeficiente numérico. Ahora que ha encontrado el área en pies cuadrados, todo lo que necesita hacer para encontrar el área de concreto de su proyecto es dividir el área en pies cuadrados por un cierto número: mientras más grueso sea su proyecto, más pequeño será el número; mientras más delgado sea su proyecto, más grande será el número. A continuación se muestran los coeficientes para algunos espesores comunes. Si el grosor de su proyecto no aparece en la lista de abajo, no se preocupe, aprenderá a calcular fácilmente su coeficiente en el siguiente paso.

Compre un poco más de hormigón del que necesita. Una buena regla empírica es agregar de 5 a 10 por ciento a su volumen calculado para tener en cuenta el derrame, el desperdicio o la sobreexcavación. Debido a que no puede esperar razonablemente usar su concreto con una eficiencia del 100 por ciento, asegúrese de pedir más de lo que realmente necesita. Por ejemplo, si ha ! calculado un volumen total de 20 yardas cúbicas (15,3 metros cúbicos)! , entonces debe pedir 1,05 × 20 = 21 yardas cúbicas (o 1,05 × 15,3 = 16,1 metros cúbicos).

please describe law of conservation of linear momentum?

Dannie Briseno: the priority is the earth is so large, what you're calling "angular momentum" is extremely left out and linear momentum is rather used as a results of the indisputable fact that's a lot extra effective and obvious. The linear momentum of a automobile comes from the automobile shifting. It has no momentum even as that is table certain. I also do not extremely get what you attempt to assert even as someone jumping adverse to a wall is gaining linear momentum.

Joie Libutti: Suppose F is the net force on a system of particles, m is the total mass of the particles, and a is the acceleration of the center of mass of the system. Newton's 2nd law givesF = maF may be split up into the external forces acting on the system and the internal forces between particles in the system.F_ext + F_int = maSuppose we have a closed system so that F_ext = 0.F_int = maNow, Newton's 3rd law causes the internal forces to cancel in pairs so that F_int = 0.0 = maIt can be shown ! thatma = m1 a1 + m2 a2 + m3 a3 +...Where each term is the rate of change of the momentum of the ith particle. Thus, if p is the net momentum of the closed system of particles,0 = (d/dt) pOr alternately,p is conserved, orp_initial = p_finalThere are many situations in which energy is not conserved due to the presence of dissipative forces. Even in these situations, momentum is still conserved. Because of this, momentum conservation is very useful for solving problems involving inelastic collisions....Show more

Isn't this only only way to lower fuel prices?

Lorine Helwick: ____Increasing supply does nothing towards solving the true problem which is that oil is finite in volume and we a running out. if we lower prices through increased supply, then, folks continue to consume. The longer we wait to re-think our energy needs, the worse the problem becomes....

Clinton Quant: Reducing demand and using alternate fuels are the only way to go. Oil is in finite quantities, it will only become more expensive if consumption continues or increases.

Dewey Heersink: Whimsy, I'm sorry you only understand half the equation. If you only reduce demand in one area, then the supplier can reduce the supply to that area, and maintain its supply to the other areas. In other words, the Saudis will only decrease how much they ship us, and continue to make their money in China or Europe.The only way to lower the price is to increase supply and reduce demand. Over the last year, American's have reduced the demand, but price continued to! go up; mainly because the Middle East just cut back on production, and speculators didn't think we would insist on producing our own oil.Price dropped seriously when the President lifted his ban, and it would drop again if Congress lifted its ban. Speculators aren't looking at what the price is today, the are gambling on a year from now. And, finally, I don't care what the "experts" in DC say, the oil men in Texas say they can get oil flowing in under 2 years. Politicians have a tendency to lie, Texas oil men don't... so I trust the oil men. ...Show more

Joie Kemmis: No. reducing demand and/or increasing supply will lower fuel prices..Gas rationing is something I would think a liberal like Obama would push for and one reason I will never vote for him..The question was about lowering fuel prices not solving a possible future problem of oil shortages. There is no reason we have to sacrifice our economy and the quality of life of millions of people while we develop alternate energy sources. Those that are the poorest are suffering the most due to the high prices but the champions of the poor (Democrats) couldn't care less.....Show more

Dan Seen: Yes, get off the petroleum addiction. Cold Turkey NOW.

Renita Sefton: Or increasing supply.Edit: Russia already tried that. "Meanwhile our people grumpled for more nylons and washing machines"Edit: You have an all or nothing style of thinking. It's possible to drill for oil to add additional supply while developing alternative resources.! Take ethanol for example: Congress has managed to almost triple the price of food making it especially harder for people in impoverished countries to eat. Maybe we should stick with oil for the time being instead of going full force into an alternative resource and not thinking through the consequences....Show more

Elfreda Grossen: Oil prices are driven by speculators who are reacting to tensions in the Middle East (where the supply comes from), and in particular between the west and Iran.When tensions ease, prices drop.If McCain is elected, and incites a war with them, we shall be screwed on a royal scale.Incidental, Russia is now calling for further negotiations between the west and Iran. This could be Iran speaking through Russia.We ought to at least listen to what they have on their brain before allowing Bush and McCain to drag us into World War III....Show more

Furthermore there was brain drain and many brilliant minds who could have helped germany were wastedanswers 3:WWII had such a huge effect on Germany's economy that it's almost impossible to separate out what effect the Holocaust might have had on its own.answers 4:Well, the problem is that the war and the allied bombing campaigns had such a huge and well defined effect on Germany's economy that the Holocaust's contribution might be hard to separate out. Still, the slave ! labor german companies gained from the people they put in those camps, combined with the money and material goods seized by the state from those folks, and the gold from their dental fillings probably had a small but significant positive effect on the German war economy. It might have been enough to pay for the camps and the poison gas and the fuel to run the ovens.*shudders* what a horrible thing!...

Your Thoughts On Vehicles Using Alternative Fuels In 5 Years?

Angelyn Ducas: Car makers are set to introduce non-petrol variants of their models. The demand for alternative fuel is directly proportional to the price and availability of different fuels and the enforcement of new emission controls. But I believe things will come together much faster than we believe as the demand does increase and the public awareness and education increases over the next few years. The time is ripe and changes are upon us. Future political administrations will help speed up this process as well....Show more

Emile Midgley: big words from a company that lead the campaign to kill the electric car so many years ago, and tried to convince Americans the best car is a SUV.Maybe we will have alternative fuels, but the most used fuel in cars, especially in the US, will be made from crude oil.

James Langmyer: YES FINALLY GOING THE RIGHT WAY

Tomeka Hameen: I don't that GM wants to do this. I don't doubt that they are telling us this, but it is ! only because Toyota is actually making a true attempt to run on alternative fuels, mainly hybrids.I think the only effective form is hybrid, but I doubt that that is even possible in the next 5 years because American power plants can't support that.The only way anything like this could possibly happen is with the help of the federal, not state, government. But with our gov, i doubt that it will happen anytime in our lifetime....Show more

Melissa Lavallie: Electric cars have been viable alternatives for 10 years, but all have been withdrawn despite sucessfull technology & customer demand - GM made sure all theirs were crushed, not even donated to MIT or anyone http://www.whokilledtheelectriccar.comIf we all went electric for personal transport it would actually improve the efficiency of the national grid http://www.acpropulsion.com/technology/v2g.htm ie a car that has a range of 200 miles, but only does the average 20 a day, means a lot of distributed stored energy.The! problem is it is prohibitivly dificult for a new entrant to t! he mass produced car market. So despite electric cars being quieter, smoother, higher torque/performance, smell-free, simple to make & cheap to maintain and run and recycleno major manufacture will bother to change while they don't have to take the risk of upsetting their global corp friends & political allies....Show more

Helen Zafar: It's a complete lie!GM couldn't care less about efficiency or environment.It was just a statement to make them look good.If they cared they would be making ELECTRIC cars charged with Solar Energy.Instead they just plan to make ANOTHER car that runs on exhaustible fuel.It's a pathetic attempt, and I do not give them credit for TRYING at all.They could do much better if they wished....Show more

Malcom Bourek: Look back thirty years and then slowly move forward, every tim! e gas prices climb, the big auto makers pull out the same old song and dance and as you can see, thirty years later nothing has changed.Now Bush is over in Saudi Arabia telling the Arabs to INCREASE OIL production so the US can waste more...wasn't this the guy that said we need to get off of foreign oil about a year ago?The entire solution rests with the people not the governments because the governments are in the pockets of big oil and the governments ARE the problem!...Show more
