velocity for the travelling marble are shown below. Notice that the size of the vector remains the same but the direction is constantly changing. Because the direction is changing‚ there is a ∆v and ∆v = vf - vi ‚ and since velocity is changing‚ circular motion must also be accelerated motion. vi ∆v vf -vi vf2 If the ∆t in-between initial velocity and final velocity is small‚ the direction of ∆v is nearly radial (i.e. directed along the radius). As ∆t approaches 0‚ ∆v becomes exactly radial

Recombinant DNA Report Our final annotated gel image sums up the successful experiments we performed over the course of 8 weeks. The image will be referred to throughout the report: Lane 1: 10 µL of ladder. Lane 2: 20 µL of a pAMP- EcoRI/HindIII double digestion. Within the double digestion‚ one can find 8 µL of pAMP‚ 1 µL of the EcoRI enzyme‚ 1 µL of the HindIII enzyme‚ 5 µL of 10x Buffer 2.1‚ and 35 µL of water. A total volume of 50 µL was present

Circular Motion Uniform circular motion is the movement of an object or particle trajectory at a constant speed around a circle with a fixed radius. The fixed radius‚ r‚ is the position of an object in uniform or circular motion relative to to the center of the circle. The length of the position vector of the circle does not change but its direction does as the object follows its circular path. In order to find the object’s velocity‚ one needs to find its displacement vector over the specific

Chapter 8- Circular Measure Additional Mathematics Module Form 4 SMK Agama Arau‚ Perlis CHAPTER 8- CIRCULAR MEASURE 8.1 RADIAN 1. In lower secondary‚ we have learned the unit for angle is degree. In this chapter‚ we will learn one more unit for angle that is radian. P r O 1 radian r Q 2. When the value of the angle 1 radian‚ then the length of the arc is equal to the length of the radius. 3. From this information‚ we can deduce that: r 1 rad r = 360 2πr 1 rad = r 2πr × 360 2π rad

thrown by a man in a straight line. Circular motion Circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform‚ with constant angular rate of rotation (and constant speed)‚ or non-uniform with a changing rate of rotation. The rotation around a fixed axis of a three-dimensional body involves circular motion of its parts. Examples of circular motion include: an artificial satellite orbiting the Earth at

DNA replication is a biological process that occurs in all living organisms and copies their DNA. DNA replication during mitosis is the basis for biological inheritance. The process of DNA replication starts when one double-stranded DNA molecule produces two identical copies of the molecule. Each strand of the original double-stranded DNA molecule serves as template for the production of the complementary strand‚ a process referred to as semiconservative replication. Cellular proofreading and error-checking

DNA: DNA is a double-stranded nucleic acid that contains the genetic information for cell growth‚ division‚ and function. DNA‚ or deoxyribonucleic acid‚ is the hereditary material in humans and almost all other organisms. Most DNA is located in the cell nucleus but a small amount of DNA can also be found in the mitochondria .The information in DNA is stored as a code made up of four nitrogen bases which are adenine (A)‚ guanine (G)‚ cytosine (C)‚ and thymine (T). these nitrogen bases are bind with
