Background Information: Spectrophotometry is a method that measures how much light is absorbed by using the electromagnetic spectrum. By seeing which colors are absorbed and which are reflected scientists can determine what a substance is without having to touch them. This is possible because each substance has a specific absorbance spectrum‚ meaning that the absorption spectrum of two different substances cannot be the same. Purpose/Hypothesis: 1. The purpose of the experiment was to determine

There she minimum wage laws pegged to hourly‚ daily and even monthly rates‚ although U.S. law is pegged to an hourly wage. Also‚ a minimum wage law usually makes it illegal for a person to sell his labor for less than the minimum wage rate The general purpose of the minimum wage is to guarantee a living wage to all workers who work a standard period of time‚ whatever that might

DETERMINING THE COST OF MATERIALS An important area of materials accounting is the costing of materials requisitioned from the storeroom for factory use. The unit cost of incoming materials is known at the time of purchase. The date of each purchase is also known‚ but the materials on hand typically include items purchased on different dates and at different prices. Items that look alike usually are commingled in the storeroom. As a result‚ it may be difficult or impossible to identify an issue

The Economics of Minimum Wage One might ask‚ what is minimum wage? Minimum wage is the lowest hourly amount an employer can pay an employee. There may be some exceptions based on the type of worker. There are two kinds of minimum wage rates‚ state and federal. Right now‚ the current minimum wage is $7.25 per hour. In some states‚ minimum wages are higher than the federal rate. Workers are paid the higher amount in those locations. Minimum wage has been a hot subject among the policy makers and

Factors affecting the rate of reaction between a metal and an acid The rate of a reaction can be measured by the rate at which a reactant is used up‚ or the rate at which a product is formed. The temperature‚ concentration‚ pressure of reacting gases‚ surface area of reacting solids‚ and the use of catalysts‚ are all factors which affect the rate of a reaction. Individual properties of substances also affect reaction rates. The scope of these properties is broad and there are few generalizations

with a minimum wage hourly rate. Many teens taking on their first job are willing to take any pay and are therefore satisfied with this rate. The current minimum wage in California is $9 and $7.25 across the United States. The minimum wage must be raised because the cost of living has gone up severely‚ the cost of education has increased‚ and it will save the government money. Since the cost of living has sky rocketed‚ it has become almost impossible to raise a family on a minimum wage job. A person

Determining lung capacity Experiment: This is the experiment of determining lung capacity. All the students in the group measured three types of different parameters: vital capacity‚ expiratory reserve and tidal volume. “Lung volumeizing refer to physical differences in lung volume‚ while lung capacities represent different combinations of lung volumes‚ usually in relation to inhalation and exhalation.The average pair of human lungs can hold about 6 liters of air‚ but only a small amount of

minimum wage laws. Minimum wage laws set wages above the going market-clearing wage in an attempt to raise market wages. People worry that this higher wage cost will cause employers to hire fewer minimum-wage employees than before the law was implemented. As a result‚ more minimum wage workers are left unemployed‚ creating a social cost and resulting in market failure. The minimum wage is the minimum hourly wage an employer can pay an employee for work. Currently‚ the federal minimum wage is $7

What Factors Affect the Rate of Photosynthesis in living leaves? Abstract: In this lab‚ four different types of leaves were tested to see the rate at which each leaf photosynthesized. This lab demonstrates how plants store light‚ capture light‚ and use light as energy for reproduction and growth‚ by photosynthesis. The control in this experiment was spinach‚ which was tested before any of the other plants were. The other plants that were tested were English Ivy‚ C4 Plant‚ and a multicolored
