Radioactivity Essay Example | Topics and Well Written Essays - 1000 words

Radioactivity - Essay Example The process can be described as occurring randomly such that one cannot be in a position to identify which nuclei will decay at any given time but using probability, we can state the number of atomic nuclei that will decay in a given time. Stable isotopes normally have a long half-life and unstable ones have a short half-life. Half-life refers to the period of time an atom requires to decay to half its quantity (Claudio, 2009). When an isotope that is radioactive in nature undergoes decay, it results into a new product. The amount of time taken to create the new product can be estimated by comparing the parent and daughter atoms. The half-life of any given element estimates the mean time that is taken for half of the parent atoms to decay into daughters but it does not describe the behavior during this process. The process as stated above is known to be random whereby one atom can take one half-life while another could last several hundred lives. This way, radioactivity can be descri bed using probabilistic mathematical methods (Piccion, 2013). Radioactive decay is a very important tool in radioactive decay in estimating the age of rocks. The aim of this report is to demonstrate the concept of radioactivity in atoms. So for every report there are some objectives to do in it, and the objective of this report is to determine the half life of the coins, investigate the relationship between decay and accumulation of coins, to determine the of coins that will be decayed and to know the averages of number of throws to reach to coins 1 or 0 in the second lab. I have expected two hypothesis for this experiment, my first theory for lab 1 is does the number of coins decayed decrease with the number of trials and the second experiment my hypothesis was 16 coins were tossed 50 times and the results used to test for the hypothesis: does it take half the number of coins two trials to decay? From the observations made and the results shown on the graph,

Discuss critically the main successes and failures of Tony Blair's New Essay

Discuss critically the main successes and failures of Tony Blair's New Labour government 1997-2007 - Essay Example This implies that the government was not stable and had no strong probability to solve governmental issues or give firm stands concerning the United Kingdom hence Blair had to work hard under his personal capacity to ensure that the UK was better placed as compared to earlier governments. Tony Blair’s regime as a Prime Minister achieved a landslide of successes though on the other side, the government failed to address some national and international challenges as discussed below (Shaw, 2012: 56). Achievements of tony Blair’s government 1. Development Tony Blair being a Member of Parliament before winning the 1997 general elections had a clue on the sidelines to follow in order to enhance development and growth of the United Kingdom. Though this seem to be unrealistic due to the less informed his cabinet was, he made a lot of positive strides across the entire world. The Prime Minister reasoned out with the all the political parties, British public as well as the media against joining the Eurozone to adopt the Euro. This act brought internal cooperation and peace as the nation spoke in one voice (Gunter & Forrester, 2008: 151). Being a learned person, Blair new well that motivation was key to success and quality work. He therefore introduced the National minimum wage and went as far as raising it. The move positively enhanced the living standards and created a great correlation to the general provision of services which include government and non-governmental based. In the early years, Tony Blair held several meetings with key African leaders showing how personally he was concerned on developing Africa and making it a free sate of success, a message that went down into giving the Africans more attention beyond the issues of aid. The Great 8 (G8) summits majorly centered on issues to do with: development through improving governance, investing in people, embracing peace and stability as well as mutual accountability (David, 2012). The long standing relationship between the South African President; Thabo Mbeki and the British government led to establishment of new approaches to develop Africa as a whole to enable the African countries to rely on their efforts unlike depending so much on donors. Today South Africa stands out to be a great republic through these unstoppable efforts (Andrew, 2013: 90). The New Labour Government invested more in realizing the goals of learning institutions through fully supporting learning processes as from lower levels to high institutions, employment of more civil servants, improving their terms of work and enhancing job creation. 2. Climatic change policy. Unpredictable weather patterns has remained a major issue to be address up to date and policy makers find it difficult due to the ever changing living patterns surrounded with scientific innovations and industrialization. The New Labour Party developed the climate change agenda in 1997 as Europe become reluctant to minimize the levels of sulp hure emissions into the air. It was later taken to be the government’s environmental policy that aimed at regulating the amount of harmful gases and other wastes eliminated into the air. Successful cooperation of Tony Blair’s government and the business firms saw more approaches developed towards tackling climatic change. Through Blair’
