Report - Coursework Example The period is deemed to be the duration taken for one complete oscillation. The frequency can be deemed to be the number of oscillations that the pendulum can make per unit time the inverse of which is the period i.e. f = 1/T. The amplitude is the longest distance that is traversed by the pendulum in reference to its equilibrium position. The displacement causes the exertion of force that tends to restore the pendulum to its equilibrium position (Nethercott & Walton 2013). The sum vector of the gravitational force of the mass of the pendulum (mg) and the tension force (T) shown in Figure 1. They constitute the restoring force whose magnitude depends on the displacement from the equilibrium position. Therefore, the restoring force F can be calculated as The negative sign is an indication that the restoring force is in the opposite direction of the displacement. For small amplitudes, ÃŽ ¸ is small and therefore ÃŽ ¸ can be used in place of sinÃŽ ¸. Therefore, the resulting equation is The aim of this experiment is to estimate the acceleration due to gravity using a pendulum. For purposes of this experiment, the independent variable is the length of the pendulum whereas the period is the dependent variable (Bolton and Bolton 2012). The table top stand with clamp was placed on a flat working surface. The string was then passed through the pendulum bob and knotted as appropriate to hold the bob in position. The string with the pendulum attached to one end was passed through the split cork, and the length of string adjusted to 0.85m before being clamped onto the retort stand. A Vernier calipers was used to measure the diameter. The length of the string was adjusted to about .8 m. Therefore, the length of the pendulum is l = ls + r .where r is the radius of the bob. The pendulum was then displaced approximately 5Â º from its equilibrium position and left to swing back and forth. The time taken for 6 complete oscillations was recorded

Point and Counterpoint - Essay Example Such a leader has the ability to influence others on a personal level and not just through exercising authority. Thus, great leaders are experts in their field, lead by example, are fair in their dealings, have a natural charisma, have good knowledge and insight, are good at communicating and influencing others. Leadership may therefore be defined â€Å"as the art of mobilizing others to want to struggle for shared aspirations† (Kouzes, 2002:30). It makes people â€Å"want to be part of the organization and not just work for the organization† (Covey, 2004:217). However, the nature of today’s globalisation also demands that leaders are not only adept in analytical and emotional intelligence but also in cultural intelligence. This is the leader’s â€Å"capability for successful adaptation to new cultural settings† (Earley, 2003) and the capability of influencing people of other cultures. These in turn requires a good â€Å"conceptual understanding of differences among cultures† (Wang, 2006), expertise in handling physical aspects of cultural differences such as greeting rituals, and emotional aspects such as appreciating the complex relationship dynamics in a diverse workforce. Global and multicultural organisations nowadays seek those who have good cultural intelligence. Whilst all the aforementioned qualities are perhaps universally accepted as essentials of good leadership, as Andrew Ma (2009) points out with respect to altruism, there can be important differences between cultures in the perception of leadership values. In a comparison of the Chinese concept of altruism based on Confucian teachings (ren) and the Western concept based on Christian teachings (agapao), the author notes, â€Å"the scope and nature of altruism is different in the two philosophies/religious traditions.† Whereas the Chinese value ‘graded love’ by loving their closer relations more dearly than others, Westerners (at least those who are more faithful to the Christian religion)
