Quadratic Applications KEY Part 1: Geometry Since area is a square unit‚ often quadratic equations must be used to solve problems involving area. Draw a picture to model each problem. Solve each using any of the following methods: factoring‚ graphing‚ or tables. Show all work. 1. The length of a rectangle is 7 meters more than the width. The area is 60 square meters. Find the length and width. Let x=width and x+7=width

OBJECTIVE For this piece of coursework I have been asked to investigate into the resistance of wires when the length is changed. INTRODUCTION The objective for my coursework (as already stated above) is to investigate how changing the length of wire can affect the resistance. There are factors which can affect how accurate our expriment is come on four levels. As in any scientific experiment‚ there are always variables ( "likely to change or vary subject to variation; changeable." ) which can

How the Length of a Wire Affects Its Resistance In my physics coursework I am going to investigate the effect of the length of a wire on its resistance. Resistance is the measure of how easy it is for current to flow through a wire. Current is the rate of flow of charge through a conductor‚ and it is measured in amps using an ammeter. To help me plan my investigation I have completed a preliminary experiment in which I investigated the effect of the thickness of a wire on its resistance‚ using

Pinworm is an intestinal infection caused by tiny parasitic worms. One of the most common roundworm infections‚ pinworm infections affect millions of people each year‚ particularly schoolchildren. But if your child develops a pinworm infection‚ don’t worry. Pinworms don’t cause any harm (just itching)‚ and it won’t take long to get rid of them. And people who have pinworms aren’t dirty — kids can get pinworms no matter how often they take a bath. Pinworm infections (also known as "seatworm infection

Nanotechnology does not have to be as small as atoms or molecules‚ but it is much smaller than anything you can see with your naked eye. Many materials exhibit unusual and useful properties when their size is reduced. Researchers who try to understand the fundamentals of these size-dependent properties call their work nanoscience‚ while those focusing on how to effectively use the properties call their work nanoengineering.
