5/2/2006 Aim: Does the resistance of a filament bulb change as the bulb gets brighter? Hypothesis: I believe that a filament bulb will have an increasing resistance depending upon the current passing through it. Equipment: *Power Supply *Wires *Ammeter *Voltmeter *Filament bulb with holder *Alligator clips *Switch Method: 1.Set up the circuit according to the schematic diagram 2.Use the alligator clips to connect the filament bulb to the voltmeter 3.Connect the power supply to the electricity

Lord of the Flies Comparative Analysis Angela Boui Throughout the book “Lord of the Flies” several different universal themes occurred. Not just in this book but in movies and TV shows as well. The different themes all show morals surrounding situations both good and bad. One main theme that is present is how people abuse power when it is not earned. This happens because people crave power and they want to be in control. In the following paragraphs‚ different themes will be linked with the book

Theory of Parabolas By Amergin McDavid A parabola is designed on a basic formula‚ Y=ax^2+bx+c‚ which allows it to achieve a curve not seen in a normal line graphed using a Y=mx+b format. To the left is a graph who’s formula is y=x^2‚ where a=1‚ b=0‚ and c=0. I have isolated the (a) factor to see its effects on the parabola. Below is a graph where I have changed the (a) multiple times. The result is that as the (a) decreases‚ the mouth of the parabola widens due to the fact that (a) is essentially

EXERCISE 2STRAIGHT LINES Question 1: Write the equations for the x and y-axes. Answer : The y-coordinate of every point on the x-axis is 0. Therefore‚ the equation of the x-axis is y = 0. The x-coordinate of every point on the y-axis is 0. Therefore‚ the equation of the y-axis is x = 0. Question 2: Find the equation of the line which passes through the point (–4‚ 3) with slope . Answer : We know that the equation of the line passing through point ‚ whose slope is m‚ is . Thus‚ the equation

Determining g on an Incline During the early part of the seventeenth century‚ Galileo experimentally examined the concept of acceleration. One of his goals was to learn more about freely falling objects. Unfortunately‚ his timing devices were not precise enough to allow him to study free fall directly. Therefore‚ he decided to limit the acceleration by using fluids‚ inclined planes‚ and pendulums. In this lab exercise‚ you will see how the acceleration of a rolling ball or cart depends on the ramp
