important questions from Hydrostatics: i. Why is it easier to lift a body in a liquid than in the air? ~ We know that‚ Upthrust =Density of fluid*acceleration due to gravity*Immersed volume of the body From the realtion above‚ it is clear that upthrust given by a fluid to a body is directly proportional to the density of the fluid. Also‚ as a matter of fact‚ the density of air is less than that of liquid. So‚ the liquid provides greater amount of upthrust than the air does. This implies that a body

Population Density Debra Smith OMM 612 Managing Social Change Prof. Martin Cain September 24‚ 2012 Population Density According to Social Indicators Research (2002) population density is “the number of people living per square kilometer in the district of the city where the respondent lived” (Social Indicators‚ proquest database). The American population is very dense. According the United States Census Bureau the current United States population is 314‚440‚872 people. In some areas of

Abstract The purpose of this experiment was to identify whether density is an extensive or intensive physical property. By using water displacement‚ the volumes of the paper clip samples were measured and the masses were obtained by using an electronic balance. Each mass and volume was unique to their sample so by using their values‚ density was used to identify substances in the lab. After conducting the experiment‚ the results showed that there was a positive slope between the different paper

Identifying a Bone Deformity Identifying a bone deformity is fairly easy if the bone is twisted or curved significantly enough that anyone could visually look at it and see that something is definitely wrong. However‚ sometimes‚ the deformities are less noticeable. In these cases‚ a doctor must do a thorough examination of the limb that is being disfigured. Measurements are taken to compare it with the other matching limb. X-rays and bone density analysis tests are sometimes also needed too. Causes

Precision‚ Accuracy‚ and Density Measurements This experience is intended to introduce the proper use of the most used laboratory equipments and glasswear that is come upon in the lab. As well‚ to determine the mass‚ volume and density of water by using various types of measuring glasswear‚ such as beakers‚ graduated cylinder‚ pipet‚ etc... The measurement of the density of water will determine the precision and accuracy of these measuring glasswear. Also‚ there will be a density calibration graph‚ used

Bone Breakdown Before taking a human anatomy and physiology class people think of a bone as a simple structural part of the body. When in reality bones are very complex and can be classified into multiple groups. The many groups they are classified into are their shapes. There are four main shapes of bones to be classified as; long‚ short‚ flat‚ and irregular. All these classifications are especially different but two of them are somewhat similar; being the long and short bones. The long bone

D – “Don’t let a broken bone get in the way” This ad was a double metaphor which confounded clarity of creative idea and main message. Women did not understand the purpose of the broken tree. For some it was a tree that had been sawed down to clear a path for walking (visually this reminded them of deforestation). For others‚ it was a broken bone which fought the idea of enduring Great Redwoods. So instead of helping the idea‚ the broken tree conflated the idea Note‚ the woman was active and walking
