Addition of Force Vectors Abstract The purpose‚ of this experiment‚ was to prove that there is a relation between the magnitude of the resulting vector‚ and the angle between the vectors that are being added. The test was performed by creating a balance between three weights tied to strings on a pulley that transferred the string on top of a graduated disc‚ which made easy the measurement of the angles between them. After performing the experiment‚ my group concluded that there is a relation

Chapter 1 Vectors‚ Forces‚ and Equilibrium 1.1 Purpose The purpose of this experiment is to give you a qualitative and quantitative feel for vectors and forces in equilibrium. 1.2 Introduction An object that is not accelerating falls into one of three categories: • The object is static and is subjected to a number of different forces which cancel each other out. • The object is static and is not being subjected to any forces. (This is unlikely since all objects are subject to the force

How Disease is Spread by Vectors In medical science or biology‚ a vector refers to an agent (microbes‚ animals or person) that does not cause disease by itself but helps in transmitting the pathogens that cause disease from one host to another. In this sense‚ the host could be humans‚ animals or plants. These vectors have contributed to the epidemic of so many diseases. Different diseases are transmitted by different vectors but some ailments share common vectors. For instance female anopheles

The main application of plasmids is as cloning vectors in gene cloning. In gene cloning‚ a fragment of DNA‚ containing the gene to be cloned is inserted into a circular molecule called the “vector” to produce recombinant DNA molecule. Plasmids are one of the most commonly used “vectors” for this purpose. They transport the gene into a host cell‚ such as a bacterium‚ which is said to be transformed with the recombinant molecule. Here‚ these plasmid vectors multiply‚ producing numerous identical copies

Plato’s allegory of the cave is a symbol/metaphor for the contrasts between ideas and what we perceive as reality. The ideas that we think and are set on‚ becomes our reality even if it may not be the truth. Plato’s allegory of the cave is an extended metaphor about prisoners who mistake sensory knowledge for the truth. Plato claimed that knowledge gained through the senses is no more than opinion and that it cannot be the ‘truth’. He says that most humans live in world of shadows‚ where we don’t

1. Gradient of a scalar field function Scalar Function: Generally‚ What Is Scalar Function? The Answer Is that a scalar function may be defined as A function of one or more variables whose range is one-dimensional‚ as compared to a vector function‚ whose range is three-dimensional (or‚ in general‚ -dimensional). Scalar Field When We Talk about Scalar Field‚ We Are Talking about the Scalar Function Being Applied to a Space (More like Euclenoid Space etc) or‚ a scalar field associates
