HSC PHYSICS 2011 HSC PHYSICS 2011 PENDULUM MOTION BY NATHAN LOCKE Image taken from http://www.practicalphysics.org/go/Experiment_480.html Pendulum Motion Aim: To determine the rate of acceleration due to gravity by using a pendulum. Background Information: Equation One: T=2πlg Where T = the period of the pendulum (s). This is the time taken for the pendulum to return to its starting position. l = length of the pendulum g = the rate of acceleration due to gravity (ms-2) * In

"If a free society cannot help the many who are poor‚ it cannot save the few who are rich" John Fitzgerald Kennedy 1917 63‚ 35th President of the USA. Why isn’t the world equal? Our world is divided in to two those who have and those who do not. Globally this division exists between the rich countries in the north and poor countries in the south. Within this broad division between the rich and the poor we find that in each country we have similar division. Even in the richest country in the

Human civilizations connected more during the third wave than during any other time in human history. The drive to expand empires and explore new regions was aided by advances in technology that allowed for easier travel‚ thus creating more connections between societies. The new ways in which societies connected in the third wave of civilizations include the conquering of environmental road blocks; trade via the Silk‚ Sea‚ and Sand roads; and the link between the societies of Europe and the Americas

EXERCISE 7 - Rotational Kinematics and circular motion 1. A wheel has a radius of 4.1 m. How far (path length) does a point on the circumference travel if the wheel is rotated through angles of 30°‚ 30 rad‚ and 30 rev‚ respectively? 2.1m‚ 1.2x102 m‚ 7.7. x102m 2. A centrifuge in a medical laboratory rotates at an angular speed of 3 600 rev/min. When switched off‚ it rotates through 50.0 revolutions before coming to rest. Find

In the above picture‚ I drew several symbols representing Paul’s third journey. The map shows his path during it‚ the burning scroll symbolize the converts in Ephesus burning their scrolls‚ the ship shows the way Paul traveled for some of his journey‚ and the crowd represents the riots in Ephesus. It is clear that Paul’s third journey was a success. He converted countless people into People of the Way‚ spreading Jesus’ good news far and wide across the Eastern area of the Roman Empire. He started

ASP 0501 EXERCISES – circular motion 1 A car travels at a constant speed around a circular track whose radius is 2.6 km. The car goes once around the track in 360 s. What is the magnitude of the centripetal acceleration of the car? 2 An astronaut in a chamber moves on a circular path‚ much like a model airplane flying in a circle on a guideline. The chamber is located 15 m from the center of the circle. At what speed must the chamber move so that the astronaut is subjected to 7.5 times the acceleration

Sir Isaac Newton I am Sir Isaac Newton. I am a mathematician and physicist‚ and one of the foremost scientific intellects of all time. I was born at Woolsthorpe‚ near Grantham in Lincolnshire‚ in 1642. I entered Cambridge University in 1661; then was elected at Fellow of Trinity College in 1667‚ then Lucasian Professor of Mathematics in 1669. I remained at the university‚ lecturing in most years‚ until 1696. Of these Cambridge years‚ in which I was at the height of my creative power‚ I singled out

The third subtheme was related to specific memories identified by the interviewees. The memories discussed were rich and detailed. Three of the respondents had experienced uncomfortable student situations with two believing the experiences were good learning experiences ultimately. Non of respondents identified uncomfortable professional memories while four talked about positive memories that reinforced for them a shared sense of humanity with psychiatric patients and only one was still having uncomfortable

The third aerial-scene of the neighborhood marks the final stage of the film. We have witnessed Lester being filmed constantly inferior in the scenes in the first portion of the movie and have witnessed him challenging that connotation in the second‚ where he is usually engaged in eye-level shots or rising above others‚ even if only for a moment. The third part of the movie‚ which encompasses one day‚ the last day of Lester’s life‚ shows the results of his work from the second section of the film
