Determining The Ratio Of Circumference To Diameter Of A Circle

- Determining the Ratio of Circumference to Diameter of a Circle In determining the ratio of the circumference to the diameter I began by measuring the diameter of one of the si objects which contained circles, then using a string, I wrapped the string around the circle and compared the length of the string, which measured the circumference, to a meter stick. With this method I measured all of the six circles. After I had this data, I went back and rechecked the circumference with a tape measure, which allowed me to make a more accurate measure of the objects circumferences by taking away some of the error that mymethod of using a string created....   [tags: essays research papers]

The Effect of the Height of a Crater on Its Diameter

- The Effect of the Height of a Crater on Its Diameter Introduction ============ A crater is formed when a meteor for outer space strikes the lunar surface. The force of the impact obliterates the meteorite and displaces part of the moons surface, pushing the edges surrounding rock. At the same time, more displaced material shoots outward from the crater. I will simulate this in the classroom by using a margarine tub full of sand and using different heights to represent the distance it travelled....   [tags: Papers]

An Investigation into the Relationship Between the Resistance of a Wire and Its Diameter and Length

- An Investigation into the Relationship Between the Resistance of a Wire and Its Diameter and Length Introduction In this investigation I hope to see whether there is a relationship between the thickness of a wire and its length with the resistance in which it produces. First of all, what is resistance. Resistance is calculated as R=V/I Where R is resistance, V = Potential Difference (Voltage) and I = Current (Amount of charge flowing per second) Resistance is the property of a conductor that restricts the flow of electricity through it, this is measure in Ω (Ohms) This Resistance can be because of many things such as the nature of the material, its tempera...   [tags: Papers]

Circumference Formula

- Prove the Circumference Formula Introduction: Archimedes is credited to be the creator of the circumference formula, but more importantly to find the first theoretical calculation of Pi. Pi is an irrational number and the digits are continuous and never come to an end. Archimedes knew he had only found an approximation of pi, he found that pi is between 3 1/7 and 3 10/71. “Pi is a name given to the ratio of the circumference of a circle to the diameter. That means, for any circle, you can divide the circumference (the distance around the circle) by the diameter and always get exactly the same number....   [tags: Archimedes, Pi, diameter, circle, mathematics]

Investigating the Resistance of Wires

- Investigating the Resistance of Wires Aim: To investigate how the diameter of a constantan wire will affect its resistance and hence the current flowing through it. Prediction: I predict that the thicker the diameter the less resistance there will be. Reason: In a metal, some of the electrons are free to move between the ions, to form a "sea" of electrons around the positive metal ions. Metals that are good conductors have more "free" electrons and therefore these electrons move easily around the positive metal ions....   [tags: Papers]

Abdominal Aortic Aneurysm

- The cardiovascular system is the most important system in our body. This system is what keeps us alive. Beating on average 30 billion times a year, our heart is never able to stop and take a break. With every beat of our heart, the cardiovascular system moves blood, gases, nutrients, and hormones throughout the intricate vasculature of our bodies. An adult body contains over 60,000 miles of vessels, which can wrap around the world two and a half times. The vessel branching off of the heart is largest artery in our body and is known as the aorta....   [tags: Medical Conditions]

Heat transfer of nanofluids in turbulent pipe flow

- Heat transfer of nanoparticle suspensions in turbulent pipe flow is studied theoretically. The main idea upon which this work is based is that nanofluids behave more like singlephase fluids than like conventional solidliquid mixtures. This assumption implies that all the convective heat transfer correlations available in the literature for single-phase flows can be extended to nanoparticle suspensions, provided that the thermophysical properties appearing in them are the nanofluid effective properties calculated at the reference temperature....   [tags: Technology, Nanofluids]

When a patient is exercising, blood vessels will become dilated and blood pressure will increase (Connexions). Patients who have a constantly high blood pressure will have a decrease in cardiac muscle tone and thin blood vessel walls. Capillaries tend to be extremely small, which causes them to have a decreased radius and an increase in airway resistance.
