Sta. Ana‚ Mariel EXPERIMENT No. 2 The Simple Pendulum Abstract A simple pendulum is one which can be considered to be a point mass suspended from a string or rod of negligible mass and allowing it to sway back and forth in a place. The objective of this experiment is to observe the motion of a simple pendulum‚ study simple harmonic motion‚ determine some factors that affect the period of a pendulum‚ and measure the value of acceleration due to gravity by use of a simple pendulum. The materials

MAKING PROCESS AND DISTILLING PROCESS Vodka is defined in the United States Standards of Identity as “neutral spirits so distilled‚ or so treated after distillation with charcoal or other materials‚ as to be without distinctive character‚ aroma‚ taste‚ or color.” As Vodka is a neutral spirit‚ it means that it can be obtained by the distillation of any product with fermentable carbohydrates on it‚ like grains (rye‚ corn or wheat) or products like potatoes‚ beets or sugar beets; even grapes. Nowadays

Distillation Objective: To illustrate the use of distillation for separating a mixture of two volatile liquids with different boiling points. Background: Distillation consists of heating a liquid until it vaporizes‚ and then condensing the vapor and collecting it in a separate container. Distillation is used to separate mixtures of liquids that either have different boiling points‚ or that have one component that does not distill. There are many types of distillation‚ each of which has a distinct

Simple Machine Joemarie A. Martinez 1-D CE Simple machine Simple machines make work easier by multiplying‚ reducing‚ or changing the direction of a force. The scientific formula for work is w = f x d‚ or‚ work is equal to force multiplied by distance. Simple machines cannot change the amount of work done‚ but they can reduce the effort force that is required to do the work! As you can see by this formula‚ if the effort force is reduced‚ distance is increased. These simple machines

SEPERATING CYCLOHEXANE AND TOLUENE BY DISTILLATION Aim: Separate two miscible liquids‚ either by macroscale or microscale process‚ using simple and fractional distillation. Compare the efficiencies of simple and fractional distillation. INTRODUCTION: The purpose of this experiment is to learn how to separate two miscible liquids by microscale process. There will be use of simple and fractional distillation. Simple and fractional distillation efficiencies will be compared. The student should have

Experienced writers use a variety of sentences to make their writing interesting and lively. Too many simple sentences‚ for example‚ will sound choppy and immature while too many long sentences will be difficult to read and hard to understand. This page contains definitions of simple‚ compound‚ and complex sentences with many simple examples. The purpose of these examples is to help the ESL/EFL learner to identify sentence basics including identification of sentences in the short quizzes that

Introduction: This experiment involves an extraction of a natural product using the techniques of steam distillation. The principle component of oil of cloves is an aromatic compound‚ which is identified by thin layer chromatography (TLC). Eugenol is widely used in dentistry‚ due to its analgesic‚ antiseptic balsamic qualities. It is ideal for curative for pulp hyperemia (the soft‚ sensitive substance underneath the enamel and dentine of a tooth) and pulp its. In dentistry eugenol is also used to

Simple Machines Definitions: Machine- A device that makes work easier by changing the speed ‚ direction‚ or amount of a force. Simple Machine- A device that performs work with only one movement. Simple machines include lever‚ wheel and axle‚ inclined plane‚ screw‚ and wedge. Ideal Mechanical Advantage (IMA)- A machine in which work in equals work out; such a machine would be frictionless and a 100% efficient IMA= De/Dr Actual Mechanical Advantage (AMA)- It is pretty much the opposite of

hanicalSimple Machines and its Mechanical Advantage What are Simple Machines? What do we mean by Mechanical Advantage? Simple Machines * creates a greater output force than the input force Therefore since work is performed by applying a force over a distance‚ with the use of these machines we can do more work with lesser effort than working with our bare hands. In short‚ they make work easier. Mechanical Advantage * The Ratio between the input force and the output force. * The measure
