JavaArray An array is a container object that holds a fixed number of values of a single type. The length of an array is established when the array is created. After creation‚ its length is fixed. You have seen an example of arrays already‚ in the main method of the "Hello World!" application. This section discusses arrays in greater detail. An array of 10 elements. Each item in an array is called an element‚ and each element is accessed by its numerical index. As shown in the preceding

NOT MARBLE NOT THE GUILDED MONUMENTS (SONNET 55) BY: WILLIAM SHAKESPEARE THEME Shakespeare believed that love is eternal and everlasting. It cannot be destroyed or withered away‚ like man-made monuments which are all doomed to destruction with the passage of time. The sonnet opposes the power of verse to death and the ravages of time‚ promising immortality to his friend by making him the subject of his poem. Q AND A Q1. Why do you think the rich and powerful……(see text Q no. 1)

INTRODUCTION Given appropriate chemicals and equipment‚ the specific heat capacity and molar mass of a metal‚ enthalpy of neutralization of an acid and base‚ and the enthalpy of solution of an unknown salt can be determined by following specific procedures. All of these procedures require the use of a calorimeter‚ which are of two types: a bomb calorimeter and a coffee cup calorimeter. Calorimeters are simply devices used to measure the amount of heat gained or lost in a system. Although this

community as a whole is altered (Friedman 2017). To study succession‚ one must use one of the following methods: to observe any patterns that occur‚ to conduct experiments that manipulate specific variables in a community‚ or to construct a model that may undergo succession. One example of an experiment that measures microbial succession was an experiment observing changes in traditional Chinese soy sauce over time (Sulaiman et al. 2014). The fermentation of the soy sauce brine revealed that the primary bacteria

AMINO ACIDS BY MEANS OF TITRATION CURVE ABSTRACT The aim of the experiment was to identify an unknown amino acid through acid-base titrations which was prepared in water to form an acidic solution. Each group prepared unknown amino acid hydrochloride. The pre-prepared basic solution was slowly added to the amino acid solution and pH change was closely observed using the pH meter. During these titrations the amino acid converted from cation to zwitterion to anion; zwitterion is an amino acid with

The Micro Chip Computer Corporation Shows a total of net sales for the years of 2000 – 2004. The total net sales have seemed to drop since 2000. I will compute the year-to-year percentage annual growth in total net sales by taking the current year total net sales and subtracting the previous years. I will then multiply that by 100 and then divide that by the previous year’s total net sales. This will give me the annual percentage growth. The formula will be (current year total net sales – previous

Discussion: First of all‚ rinse all the apparatus that being used in the experiment with hydrochloric acid (HCL) then followed with distilled water (H₂O). Then‚ prepared the saturated calcium hydroxide (Ca (OH) ₂) solution into a filter funnel and filter paper over a second conical flask. Pour 100.00mL of saturated Ca (OH)₂ solution into a beaker and pour the solution through the filter paper by flowing the solution through a glass rod. After that‚ use a thermometer to measure the temperature of

The pH scale is used to measure how acidic or basic a living cell can be. The pH scale ranges from 0-14; 0-6 being acidic‚ 8-14 being basic and 7 being neutral. There are many factors
