enclosed by a shape or object‚ how much 3-dimensional space it occupies. It can be occupied by a solid‚ liquid or gas. The volume can be measured in cubic meters‚ cubic centimeters‚ or liters. Sometime around 250 BCE‚ the Greek mathematician Archimedes was given the task of determining whether a craftsman had defrauded the King of Syracuse by replacing some of the gold in the King ’s crown with silver. The story goes that he was easing down into the bath and he noticed that the further down he

Introduction Hydrostatic weighing is an indirect measurement used to predict body fat percentage. It is typically the most accurate means of determining body fact percentage‚ and is based on measuring an individual’s body density. Archimedes’ principle explains that the upward buoyant force exerted on a body immersed in a fluid is equal to the weight of the fluid that the body displaces. Due to the fact that body fat is less dense than water‚ it increases one’s buoyancy‚ while the fat-free mass

variations in a fluid are typically caused by gravity (since P = P0 + ρgh)‚ but in general buoyant forces act opposite the direction of the frame of reference acceleration. Under conditions of apparent weightlessness there can be no buoyant forces. Archimedes’ Principle The magnitude of the buoyant force on an object is equal to the weight of the fluid it displaces. B = ρgVdisplaced The factors that affect buoyancy are … the density of the fluid‚ the volume of the fluid displaced‚ and the

Apollonius of Perga Apollonius was a great mathematician‚ known by his contempories as " The Great Geometer‚ " whose treatise Conics is one of the greatest scientific works from the ancient world. Most of his other treatise were lost‚ although their titles and a general indication of their contents were passed on by later writers‚ especially Pappus of Alexandria. As a youth Apollonius studied in Alexandria ( under the pupils of Euclid‚ according to Pappus ) and subsequently taught at the university

Title: Archimedes principle Objective: To use Archimedes Principle to determine the density of an object more dense than water. Introduction: Archimedes ’ principle is a law of physics stating that the upward force (buoyancy) exerted on a body immersed in a fluid is equal to the weight of the amount of fluid the body displaces. In other words‚ an immersed object is buoyed up by a force equal to the weight of the fluid it actually displaces. Hence‚ the buoyant force on a submerged object is the

Archimedes was among the greatest mathematicians of antiquity. Mathematicians usually cover a breadth of topics within mathematics in their undergraduate education‚ and then proceed to specialize in topics of their own choice at the graduate-level. In some universities‚ a qualifying exam serves to test both the breadth and depth of a student’s understanding of mathematics; the students who pass are permitted to work on a doctoral dissertation. A mathematician is a person with an extensive knowledge of mathematics who

A fertilizer spreader is a metal hopper with an adjustable trough underneath for applying an even layer of fertilizer over lawns and gardens. Some spreaders connect with a tow hitch to the back of a tractor. Smaller models have a handle and wheels for pushing the spreader yourself. As with all garden tools‚ cleaning your spreader after each use will prolong the life of the equipment and ensure proper operation. A garden hose may be used‚ but a power washer works best. 1. Empty the hopper of all

Luckily for me‚ I’m standing next to a power switch and if I pull the lever of the switch‚ the train will divert into a different track. However‚ there is one person working on this track and if I pull the switch‚ that rail worker will die. Here’s what I would do. I would in fact pull the lever of the switch to spare the
