GEK1521 / PC1326 Tutorial 1 ( Lecture 1-4: Units‚ Vectors & Mechanics ) 1. When a sphere moves through a fluid slowly‚ it usually experiences a drag force. This force is determined by the radius of the sphere r‚ the speed of the sphere v‚ and the viscosity of the fluid (in the unit of [kg/(m∙s)]). Using dimensional analysis‚ determine how the force depends on these factors. 2. Three vectors A‚ B‚ and C add together to yield zero: A + B + C = 0. The vectors A and C point in opposite directions

CHAPTER 1 In modern world of technological advancement‚ there are a lot of applications that are used every day. For example‚ an airplane relies on Bernoulli’s Principle to generate lift on its wings. Rare cars employ the velocity and pressure dynamics specified by Bernoulli’s Principle to keep their rare wheels on the ground‚ even while zooming off at high speed. It is successfully employed in mechanism like the carburetor and the atomizer. The study focuses on Bernoulli’s Theorem in Fluid Application

Leon Jones Jr Albert Einstein Albert Einstein was born in March 14‚1879 he was born in Ulm‚ Germany He graduated from Swiss Federal Institute its spell wrong I fixed it for you. I fixed everything highlighted of Technology in Zurich and he moved to Berlin in 1914 to become a professor and when he got to Berlin he published a theory a paper. He also published a Radiation Theory paper and he was awarded for Nobel prize in Physics. After awhile in Berlin he moved to Princeton

Chapter 7 is titled Reflecting on Creation and Providence. The basis of this chapter is that we need to rely on God and his almighty power and wisdom when contemplating chance. It is important to remember that God has provided guidance on our everyday lives and He always will. Psalm 121:2 reads “my help comes from the Lord‚ the maker of heaven and earth.” This provides that God‚ the creator of heaven and earth‚ is willing to assist humans on earth and has remained provident through all of humanity

CHAPTER 27. FLEXIBLE PAVEMENT DESIGN NPTEL May 24‚ 2006 Chapter 27 Flexible pavement design 27.1 Overview Flexible pavements are so named because the total pavement structure deflects‚ or flexes‚ under loading. A flexible pavement structure is typically composed of several layers of materials. Each layer receives loads from the above layer‚ spreads them out‚ and passes on these loads to the next layer below. Thus the stresses will be reduced‚ which are maximum at the top layer and

Biography of a Mathematician: Sir Isaac Newton Sir Isaac Newton has made an impact on scientists to this day. Even though his discoveries derived in the late 1600s‚ we are still affected today in the present. The ideals and theorems he sought out still hold legitimate centuries after his time. With the information laid out for them‚ a scientists using his theories can improve their research to achieve fame themselves. “Some would say that he was the greatest product of the Enlightenment‚ the

volleyball spike and I’m identify one major weakness in my technique and applying two biomechanical principles to justify why it is my weakness. Biomechanics applies to the science field in every sport; it is basically the principals and laws of mechanics about human performance. Though the evaluation of the video footage which was taken to show my personal performance in the volley ball spike‚ it clearly shows the major weakness in my technique compared to the right technique. The basic correct

Pascal’s law Pascal’s law or the principle of transmission of fluid-pressure is a principle in fluid mechanics that states that pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure ratio (initial difference) remains the same.[1] The law was established by French mathematician Blaise Pascal.[2] Contents [hide] 1 Definition 2 Explanation 3 Applications 4 See also 5 References Definition[edit source | editbeta]

VIBRATIONAL-ROTATIONAL SPECTRA OF HCl Physical Chemistry Laboratory II‚ CHEM 3155.001 April 20‚ 2012 Introduction and Objective The experimental objective of this lab was to collect an IR spectrum of gaseous HCl and from it the experimental rotational constant‚ B‚ and fundamental vibration frequency‚ v0‚ can be calculated(1). The concept of infrared spectroscopy deals with the infrared region of the electromagnetic spectrum. Molecules absorb at specific resonant frequencies that are characteristic

Experiment 2: Kinematics of Human Motion Abstract Kinematics is the branch of classical mechanics that describes the motion of bodies and systems without consideration of the forces that cause the motion. There are four activities done in this experiment‚ graphical analysis of human motion‚ where displacement vs. time and velocity vs. time were graphed. Graphical analysis of motion where in the 10th seconds the total displacement is 14.69m‚ average velocity is 1.47 m/s. Reaction time where
