When you take the absolute value of a number, the result is always positive, even if the number itself is negative. For a random number x, both the following equations are true: This means that any equation that has an absolute value in it has two possible solutions. If you already know the solution, you can tell immediately whether the number inside the absolute value brackets is positive or negative, and you can drop the absolute value brackets.
They then note that plants are the ONLY actual source of food on Earth, and if the plants all die, there would then be no available food for any animals or humans. It is quite an important subject to contemplate. Politicians and businessmen are NOT going to do anything significant about it, except to give impressive speeches about what they PLAN to do.
And doing irrelevantly small things! They still do not seem to comprehend the scale of the problem.
Press Conferences are being given regarding ideas of extracting carbon dioxide from the atmosphere and pumping it into the ground! We all know that there is Radon gas that is seeping up out of the earth everywhere!
They also seem to be envisioning a rather small quantity of carbon dioxide gas that they would be able to process in such ways. We will shortly see that we ADD at least trillion MORE cubic feet of carbon dioxide to the atmosphere, and that the US government Research Station at the South Pole confirms this fact, also describable as just over 30 billion metric tons of carbon dioxide being added each year.
All this effect is just from burning the fossil fuels of petroleum oilnatural gas and coal. So, being a fairly creative Physicist, I have spent several years in trying to think and research into innovative ideas to consider. Unfortunately, byI had already considered and dismissed around different ideas!
Pretty much ANY "mechanism" is just too ridiculously tiny to deal with the scale of this situation. Since it is a gas, it is actually around ,, cubic feet of carbon dioxide that we humans are collectively pumping into the atmosphere each year.
A number so big it is almost meaningless!
Consider a giant football stadium, one that holdspeople. Consider the amount of air gas contained within its space, if it had an imaginary lid on it.
Around 12, such stadiums would be required to contain all the carbon dioxide that our vehicles and powerplants add to the atmosphere every year! And all this equipment would need a LOT of power to run.
Where would THAT com from??? Even if it could be somehow removed from the atmosphere, and then somehow converted into either compressed gas or liquid, consider that we are talking about 30 billion tons that get added every year!
It is certainly true that developing countries, specifically China, are rapidly growing, building new electric power plants at the rate of about one per week, and building and buying vehicles at amazing rates. They intend to catch up to the United States in most ways, which will include energy wastefulness and generation of carbon dioxide.
So the future figures to get far worse regarding the amounts of carbon dioxide that the world's people send into the atmosphere. If there were a million times that much equipment, and we had the power to run them all, we STILL would not be able to remove the amount of carbon dioxide we put into the atmosphere each year, much less actually gain any ground!
So, an assortment of mechanical concepts actually work, but for such miniscule amounts that they are not even worth seriously considering. Only one currently used process has even measurable success, something called the Solvay Process. There are around factories around the world which use that process, and they collectively remove a few million tons of carbon dioxide from the atmosphere.
We would need thousands of times as many Solvay Process factories operating, and they would need to use up a lot of energy, which would certainly come from burning fossil-fuels.
Nature Nature has its own way of removing carbon dioxide from the atmosphere, and even giving out oxygen in the process, the process that most plants use called photosynthesis. The chemical reaction of Photosynthesis is generally this one: It's really an interesting process, taking generic water usually from the ground and carbon dioxide from the air and energy from sunlight and creating a complex hydrocarbon molecule called glucose and releasing oxygen in the process.
Essentially all living things exist because of this single chemical reaction, because we all use that glucose as the energy source for nearly all biological functions.Remember that an absolute value represents a distance from zero, so if we are given two solutions and asked to write an absolute value equation, we'll somehow need to figure out what is the starting place (like zero) and how far should we be traveling in each direction to arrive at those solutions.
Global warming is an assertion that the entire earth’s surface is warming. Unfortunately, many individuals, and the popular media, often use the terms “climate change” and “global warming” interchangeably. When you take the absolute value of a number, the result is always positive, even if the number itself is negative.
For a random number x, both the following equations are true: |-x| = x and |x| = x. This means that any equation that has an absolute value in it has two possible solutions. You can put this solution on YOUR website!
9 and 21 differ by Sinxe half of 12 is 6, we want the absolute value part to result in the values 6 and -6 in the equation. Find Absolute Value Functions lesson plans and worksheets.
High schoolers graph functions that are given, and then they write the equations for the completed graphs. There are several problems included, and they are designed to be used without calculators. Translating the graph of an absolute value equation horizontally based on the. Jul 21, · For instance, the absolute value of 2 is 2 and the absolute value of -2 is also 2.
To solve an absolute value equations we need to create the two cases: the positive case and the negative case.
