Free Essays on Refugees And Asylum Seekers

MIGRANTS: Since the beginning of human society, people have moved from place to place, from region to region, from country to country. Some travelled by foot, others by motor vehicle or boat or plane. Every country in the world has experienced people coming and going at one time or another. Today, about one hundred million people are making the choice to leave the country of their birth and live somewhere else. Perhaps they can get a better job in another country perhaps they have married a person from another country perhaps their health demands a different climate for their well-being. Their reasons are many and varied. It is said that one in every hundred people in the world today does not live in the country of their birth. Migration is nothing new. Australia is a nation of migrants. Apart from Australia’s indigenous peoples, our ancestors all came to Australia from other countries by boat or plane. Australia has attracted migrants from the four corners of the globe at every stage of non-indigenous settlement since 1770. Despite such policies as the White Australia Policy’, Australia, like many other countries, has welcomed migrants, those who've come across the seas’ because this country needed a bigger population for its very survival as a nation. While the benefits of migration are incalculable, every country has the right to regulate its intake of migrants. Like most countries, Australia sets criteria for all people wishing to migrate and live here. REFUGEES: There is another group of people who come to our shores. These people are not migrants. They are refugees. Their situation is very different. They have fled their homeland because they had no choice. Sometimes war has been the catalyst for their moving. Sometimes they leave because of fear of being tortured or killed. When refugees migrate’ their transport’ is often harsh and terrifying. Some clamber over barbed wire fences some swim shark infes...

Calculating Density - Worked Example Problem

Calculating Density Problem Density is a measure of how much matter is in a space. It is expressed in units of mass per volume, such as g/cm3 or kg/L. This is a worked example of how to calculate the density when given the volume and mass of a substance. Sample Density Problem A brick of salt measuring 10.0 cm x 10.0 cm x 2.0 cm weighs 433 grams. What is its density?Solution:Density is the amount of mass per unit volume, or:D M/VDensity Mass/VolumeStep 1: Calculate VolumeIn this example, you are given the dimensions of the object, so you have to calculate the volume. The formula for volume depends on the shape of the object, but its a simple calculation for a box: Volume length x width x thicknessVolume 10.0 cm x 10.0 cm x 2.0 cmVolume 200.0 cm3Step 2: Determine Density Now you have the mass and the volume, which is all the information you need to calculate density.Density Mass/VolumeDensity 433 g/200.0 cm3Density 2.165 g/cm3Answer:The density of the salt brick is 2.165 g/cm3. A Note About Significant Figures In this example, the length and mass measurements all had 3 significant figures. So, the answer for density should also be reported using this number of significant figures. Youll have to decide whether to truncate the value to read 2.16 or whether to round it up to 2.17.
