HelpOut - Recent questions and answers Powered by Question2Answer Answered: What is Microeconomics? <p><strong>Microeconomics </strong>(<em>from Greek prefix mikro- meaning "small" + economics</em>) is a branch&nbsp;economics that studies the behaviour of individuals and firms in making decisions regarding the allocation of scarce resources and the interactions among these individuals and firms.&nbsp;</p><p>&nbsp;One goal of microeconomics is to analyze the market mechanisms that establish relative prices among goods and services and allocate limited resources among alternative uses. Microeconomics shows conditions under which free markets lead to desirable allocations.&nbsp;</p><p>It also analyzes market failure, where markets fail to produce efficient results. Microeconomics stands in contrast to macroeconomics, which involves "the sum total of economic activity, dealing with the issues of growth, inflation, and unemployment and with national policies relating to these issues".</p><p><strong>Microeconomics</strong> also deals with the effects of <strong>economic policies</strong> <em>(such as changing taxation levels</em>) on microeconomic behavior and thus on the aforementioned aspects of the economy.[4] Particularly in the wake of the Lucas critique, much of modern macroeconomic theories has been built upon microfoundations—i.e. based upon basic assumptions about micro-level behavior.</p> Economics Mon, 18 Mar 2019 16:51:10 +0000 Answered: What is Macroeconomics? <p><strong>Macroeconomics</strong> (from the Greek prefix makro- meaning "large" + economics) is a branch of economics dealing with the performance, structure, behavior, and decision-making of an economy as a whole.&nbsp;</p><p>This includes regional, national, and global economies.</p><p><strong>Macroeconomists</strong> study aggregated indicators such as <strong>GDP</strong>, unemployment rates, national income, price indices, and the interrelations among the different sectors of the economy to better understand how the whole economy functions.&nbsp;</p><p>They also develop models that explain the relationship between such factors as national income, output, consumption, unemployment, inflation, saving, investment, international trade, and international finance.&nbsp;</p><p>&nbsp;While macroeconomics is a broad field of study, there are two areas of research that are emblematic of the discipline: the attempt to understand the causes and consequences of short-run fluctuations in national income (the business cycle), and the attempt to understand the determinants of long-run economic growth (increases in national income).

I=V/R Science Fri, 15 Mar 2019 15:47:19 +0000 Answered: How long does an oversized piston rings lasts in a rebuilt engine <p>Piston rings should be changed by a knowledgeable mechanic. The engine must be fully disassembled to change the rings. You also must change the bearings on the crankshaft and the connecting rods. Replacing the piston rings is considered a engine rebuild and you cannot just change them as you must ensure that the cylinder is true, meaning that it is straight from the top of the cylinder to the bottom, and that the cylinder is perfectly round, as well. This requires a special set of micrometers, so it's best to take the block to a machine shop to have it cleaned and checked. Replacing the rings is relatively quick, if someone is dedicated to the job. <strong>It can take several weeks</strong>, if a mechanic is doing the job for you, because it is a very intense job, requiring engine removal, disassembly, and as previously stated, possible machine-work.</p> Engineering & Technology Fri, 15 Mar 2019 11:55:34 +0000 Answered: What is Knee Voltage <p>Knee voltage (<a rel="nofollow" href="">cut in voltage</a>)&nbsp;</p><p>The forward voltage at which the current through the<strong> P-N Junction</strong> starts increasing rapidly is called as Cut in voltage or knee voltage</p><p><img alt="" src="" style="height:122px; width:100px"><img alt="" src="" style="height:154px; width:200px"></p> Engineering & Technology Fri, 15 Mar 2019 10:07:23 +0000 Answered: What is L'Hospital's rule <p><span style="font-family:Comic Sans MS,cursive"><span style="font-size:20px"><strong>L'Hôpital's rule:</strong></span></span></p><p>In <a rel="nofollow" href="">mathematics</a>, and more specifically in calculus,<strong> L'Hôpital's rule</strong> or <strong>L'Hospital's rule</strong> <em>(French: [lopital])</em> uses derivatives to help evaluate <strong>limits</strong> involving <strong>indeterminate forms.</strong> Application (or repeated application) of the rule often converts an indeterminate form to an expression that can be evaluated by substitution, <u>allowing easier evaluation of the limit.</u>&nbsp;</p><p>The rule is named after the <em><strong>17th-century </strong>French mathematician</em> <u><strong>Guillaume de l'Hôpital</strong></u>.

However, there are some home remedies that can help manage this condition. Some of the more common methods include:</p><ul><li><u><strong>&nbsp;Apply a cold compress</strong></u>. A cold compress can help reduce swelling and shrink dilated blood vessels. This can reduce the appearance of puffiness and help eliminate dark circles. Wrap a few ice cubes in a clean washcloth and apply to your eyes. You can also dampen a washcloth with cold water and apply it to the skin under your eyes for 20 minutes for the same effect. Repeat this process if the cloth becomes warm or if the ice melts.&nbsp;</li><li><u><strong>Get extra sleep.</strong></u> Catching up on sleep can also help reduce the appearance of dark circles. Sleep deprivation can cause your skin to appear pale, making the dark circles more obvious. Allow yourself seven to eight hours of rest to prevent dark circles from appearing.&nbsp;</li><li><u><strong>Elevate your head.</strong></u> While sleep deprivation can play a part in producing those dark bags under your eyes, sometimes it’s how you sleep. Elevate your head with a few pillows to prevent fluid from pooling under your eyes which can make them look puffy and swollen.&nbsp;</li><li><u><strong>Soak with tea bags</strong></u>. Applying cold tea bags to your eyes can improve their appearance. Tea contains caffeine and antioxidants that can help stimulate blood circulation, shrink your blood vessels, and reduce liquid retention beneath your skin. Soak two black or green tea bags in hot water for five minutes. Let them chill in the refrigerator for 15 to 20 minutes. Once they’re cold, apply the teabags to your closed eyes for 10 to 20 minutes. After removing, rinse your eyes with cool water.&nbsp;</li><li><u><strong>Conceal with makeup</strong></u>. While makeup and cosmetics do not cure dark eye circles, they can help to camouflage them. Concealers can cover dark marks so they blend in with your normal skin color. However, as with any topical treatment or makeup product, use proper care. Some products can cause your symptoms to worsen and may trigger an allergic reaction. If you begin to experience irregular symptoms from any topical treatment, stop use immediately and schedule a visit with your doctor.&nbsp;</li></ul><p><span style="font-family:Trebuchet MS,Helvetica,sans-serif"><strong><span style="font-size:20px">Medical treatments</span></strong></span>&nbsp;</p><p>For a more effective and permanent solution, some medical treatments are available to reduce the appearance of dark circles.</p><p>Some of the more common methods include:</p><ul><li>Chemical peels to reduce pigmentation.&nbsp;</li><li>Laser surgery to resurface the skin and enhance skin tightening.&nbsp;</li><li>Medical tattoos to inject pigment into thinning skin areas.&nbsp;</li><li>Tissue fillers to conceal blood vessels and melanin that are causing skin discoloration beneath your eyes.&nbsp;</li><li>Fat removal to remove excess fat and skin, revealing a smoother and more even surface.&nbsp;</li><li>Surgical implants of fat or synthetic products&nbsp;</li></ul><p><em>Before deciding on any cosmetic procedure, discuss your options with a doctor</em>.</p><p>&nbsp;<strong>Invasive medical treatments can be expensive, painful, and often require a long recovery time.&nbsp;</strong></p><p><u><strong>Outlook</strong></u></p><p>For many people,<strong> <a rel="nofollow" href="">dark circles</a>&nbsp;</strong>are temporary and are often an indication of aging or lack of sleep.&nbsp;</p><p>Though there are a number of at-home and medical treatments available to improve the appearance of your eyes, dark circles are typically no cause for alarm.&nbsp;</p><p><em>However, if the discoloration or swelling worsens over time, schedule a visit with your doctor or dermatologist to ensure you have correctly diagnosed the issue and are receiving the best treatment.</em></p> Health & Lifestyle Mon, 11 Mar 2019 01:34:39 +0000 Answered: what is the full meaning of A.

With Word (or any other word processor software), you can write out text and format it with different fonts, sizes, and colors. Images and tables and bullet points can be added as well. This is all done through the word processor's graphical user interface. An HTML file is similar, except it does not have a GUI. Instead, it is entirely written out in plaintext, so all the formatting instructions must be typed out as HTML tags (for example, &lt;b&gt; or &lt;center&gt;.) This "language" of tags is how we can format the appearance of a webpage. Programming languages, on the other hand, can process data and make decisions. You can store data such as text strings and integers, and then manipulate these values to perform calculations. For example, doing some math or sorting text alphabetically are kinds of data processing that you cannot do in HTML. Programming languages can also make decisions about what instructions they should execute. Depending on if a certain condition is true or false, a set of instructions may be executed or skipped by a program.</p><p>Programming languages also have ways of executing instructions over and over again in loops. Loops, if-else statements, and other such instructions are called flow control statements.<strong> All programming languages have these flow control statements, but HTML (and Microsoft Word) do not.</strong></p> Engineering & Technology Sun, 03 Mar 2019 22:23:13 +0000 Answered: is fx=x^2 a function? <p>Yes!

Light exercise, such as riding a stationary bicycle for a few minutes before bedtime, also may help prevent cramps while you're sleeping.</li></ul><p></p><p>See&nbsp;<a rel="nofollow" href="">here</a>&nbsp;for reference.</p> Health & Lifestyle Fri, 01 Mar 2019 09:38:09 +0000 Answered: What is Abdominal Aorta Aneurysm <p><span style="font-size:22px"><span style="font-family:Comic Sans MS,cursive"><strong>Abdominal aortic aneurysm</strong></span></span></p><p><span style="font-size:18px">Abdominal aortic aneurysm (<strong>AAA or triple A</strong>) is a localized enlargement of the abdominal aorta such that the diameter is greater than 3 cm or more than <strong><em>50%</em></strong> larger than normal diameter.&nbsp;They usually cause no symptoms except when ruptured.&nbsp;Occasionally, abdominal, back, or leg pain may occur.&nbsp;Large aneurysms can sometimes be felt by pushing on the abdomen.&nbsp;Rupture may result in pain in the abdomen or back, low blood pressure, or loss of consciousness, and often results in death.&nbsp;<strong>AAAs</strong> occur most commonly in those over 50 years old, in men, and among those with a family history.&nbsp;Additional risk factors include smoking, high blood pressure, and other heart or blood vessel diseases.&nbsp;Genetic conditions with an increased risk include Marfan syndrome and Ehlers-Danlos syndrome.&nbsp;<strong>AAAs </strong>are the most common form of aortic aneurysm.&nbsp;About <strong>85%</strong> occur below the kidneys with the rest either at the level of or above the kidneys.&nbsp;In the United States, screening with abdominal ultrasound is recommended for males between 65 and 75 years of age with a history of smoking.&nbsp;In the United Kingdom and Sweden, screening all men over 65 is recommended.&nbsp;Once an aneurysm is found, further ultrasounds are typically done on a regular basis.&nbsp;Not smoking is the single best way to prevent the disease.&nbsp;Other methods of prevention include treating high blood pressure, treating high blood cholesterol and not being overweight.&nbsp;Surgery is usually recommended when an AAA's diameter grows to &gt;5.5 cm in males and &gt;5.0 cm in females.&nbsp;Other reasons for repair include the presence of symptoms and a rapid increase in size <em>(more than one centimeter per year</em>).&nbsp;Repair may be either by open surgery or endovascular aneurysm repair (<strong>EVAR</strong>).&nbsp;As compared to open surgery, <strong>EVAR </strong>has a lower risk of death in the short term and a shorter hospital stay, but may not always be an option.&nbsp;There does not appear to be a difference in longer term outcomes between the two.&nbsp;With <strong>EVAR</strong> there is a higher need for repeat procedures.&nbsp;<strong>AAAs</strong> affect between 2 and 8% of males over the age of 65.&nbsp;Rates among women are one-fourth as high.&nbsp;In those with an aneurysm less than 5.5 cm the risk of rupture in the next year is less than 1%.&nbsp;Among those with an aneurysm between 5.5 and 7 cm, the risk is about 10%, while for those with an aneurysm greater than 7 cm the risk is about 33%.&nbsp;Mortality if ruptured is 85% to 90%.&nbsp;During 2013, aortic aneurysms resulted in 168,200 deaths, up from 100,000 in 1990.&nbsp;In the United States AAAs resulted in between 10,000 and 18,000 deaths in 2009.</span></p><p><u><em><span style="font-size:18px">See&nbsp;<a rel="nofollow" href="">here</a>&nbsp;for reference</span></em></u></p> Biology Thu, 28 Feb 2019 11:48:36 +0000 Answered: List of all mathematical symbols? <p>To see the list of all math symbols, click&nbsp;<strong><a rel="nofollow" href="">here</a></strong></p> Mathematics Thu, 28 Feb 2019 11:18:11 +0000 Answered: How do I Edit PDFs Online for Free <ul><li>Upload your PDF to your Google Drive. <strong>Click New &gt; File Upload</strong> and navigate to the location where your file is saved on your computer.</li><li>Once the upload is complete, go to the file in your Google Drive, right click it and select <strong>Open With &gt; Google Docs. </strong></li><li>Your PDF will now open up as an editable document in Google Docs.</li><li>Once you’re done editing it, you can save it to your computer as a PDF or Word Document, among other file formats. <strong>Click File &gt; Download </strong>as and select your file type to save your edited document.</li></ul><p></p> Engineering & Technology Wed, 27 Feb 2019 00:47:42 +0000 Answered: What is the connection between Earthquake and Plate Tectonics? <a href="" rel="nofollow" target="_blank"></a><br /> <br /> Relationship between Earthquakes and Volcanic Eruptions Engineering & Technology Tue, 26 Feb 2019 21:54:07 +0000 What is the connection between Volcano and Plate Tectonics?
