1. What are the spring constant (k) is for spring 1 and spring 2? What are the units of k? Which spring is stiffer? Fs= kx k is the spring constant and it is measured in N/m or in kg•m/s2 Spring constant for Spring 1= . 49=k(. 01)= 49 ? k=49 N/m Spring constant for […]

The goal of this experiment was to determine the viscosity of given liquids. Two different methods were employed, the first measures time of flow of several methanol-water solutions, from point A to point B. The second method involves dropping a foreign object, in this case a sphere, into a cylinder of glycerol and measuring the […]

We propose a versatile approach to improve compliance to Principles 1 and 8 of the Global Compact. The initiative aims to address human rights and environmental protection, with business partners as the primary target. According to the Forbes 2000 list (Forbes 2000 2005), Toyota Motor Corporation is recognized globally as one of the leading multinational […]

This lab consisted of the use of various materials. We used four orange flags in order to mark a 30x15m sampling area in which we collected our data from. To measure out the area, we used a thirty meter measuring tape and to determine the density (plants per meter squared) of clovers in the lawn, […]

Mud weight otherwise known as drilling fluid density is a very important property of the drilling fluid which must be determined regularly during the drilling process. It is defined as the weight per unit volume of the drilling fluid or drilling mud usually expressed in units of g/cm3 or more conveniently lb/gal. Drilling fluid density […]

Kinds of Love Love is a deep sense of acceptance and commitment to some person, object or activity. There are different kinds of love including parental, love between friends, love of a child for his or her parents, patriotism or love of one’s homeland and romantic love. Once puberty has set in, the adolescent is […]

I did this lab to find out the differences between chemical and physical changes. I also did this lab to learn the signs that would indicate the chemical reactions and physical changes. I needed to learn the odor change, color change, bubbles or gas, irreversible, temperature changes and finger prints. By the end of the […]

The volume of the air sample at the high temperature, (Vn),decreases when the sample is cooled to the low temperature and becomesV1. All of these measurements are made directly. The experimental data is then used to verify Charles’law by two methods: 1. The experimental volume (V””o) measured at the low temperature is compared to the […]

There are many reasons that eBay defeat in the competition with Taobao. com in the Chinese Internet C2C market. First, based on research of C2C market in China, the user (seller) of the website is price sensitive. Since Taobao launched no-free model, eBay lost their customers. Furthermore, eBay’s payment services did not fit the Chinese […]

Abstract Caffeine, (C8 H10 N4 O2) a white, crystalline alkaloid known as a nervous system stimulant found commonly in tea leaves and coffee, can be extracted using the method of sublimation with the use of Methylene Chloride (CH2Cl2) and Sodium Hydroxide; both can repeatedly rinse the green (unroasted) coffee beans from the caffeine. Keywords: Caffeine, […]

Obtain a reference of temperatures effect on gas using Charles’ law when heating a capillary tube in water on a heated hot plate.Then, cooling the same capillary tube with ice while measuring the temperatures cooling effect on the gas bubble inside the capillary tube. Measurements of temperature change are taken with microLAB sensor and graphed […]

Introduction In this week’s lab experiment, the rate of decomposition of hydrogen peroxide forming oxygen gas will be observed and studied. Since the rate of a chemical reaction is dependent on two things; the concentrations of the reactants and the temperature at which the process is performed, the rate can be measured at which a […]

INTRODUCTION Lipids are organic compounds found in living organisms that are insoluble or slightly soluble in water but soluble in non-polar organic solvents. Lipids can be classified into four groups which are -fats, oils, and waxes, -compound lipids, -steroids, and -derived lipids. Various experiments are done on lipids. Some tests are for saturation, presence of […]

In the face of globalization, people are forced to learn to communicate in other languages other than their native ones. Many people especially students acquire the skills their careers in other nations thus requiring them to learn the language of the land which they live in. The search for jobs also causes people to travel […]

The purpose of this lab was to find the theoretical and experimental percentage yields of the double displacement reaction between the solutions Lead (II) Nitrate (PbNO3) and Potassium Iodide (KI). It is important to obtain amounts of Lead (II) Nitrate and Potassium Iodide as close to 1. 44g as possible. This reaction creates Lead (II) […]

For HR database, a normalized structure is essential to avoid data redundancy and anomalies. Every table should be linked through primary key and foreign key relationships. The parent table’s primary key should serve as the foreign key for the child table. An employee’s personal information must be stored in a separate table, which is the […]

Associate Level Material Comparison Worksheet Use the table below to compare extrusive and intrusive rocks. Describe and compare each type in at least 150 words. Extrusive Rock Extrusive rocks, also known as volcanic rocks, are formed when magma reaches the earth’s surface and cools into lava. These rocks are created through volcanic eruptions where lava […]
