Introduction
For this experiment, the focal length is taken to be the image distance that is in correspondent to an infinite object distance; in which case, the incoming light rays are taken to be parallel. By performing this experiment, it presents a platform for determining the focal length by using the focal length equation:
1f= 1p+1q
Whereby, f is the focal length, q is the object distance and p is the image distance. To get these two variables (object distance and image distance) involves focusing the image of an object under illumination on a screen and the measuring ...

Introduction
Chromatic aberration results from the condition of state in which a lens fails to focus all colors passing through it at the same focal point. The failure occurs when the lens has got more than one refractive indices meaning that there also exists more than one focal point. Reason being that the focal point of a lens depends on its refractive index.
There exist two types of chromatic aberrations one being axial and the lateral. The axial type of aberration ...

A lens is an optical device used to alter the path of light in various optical applications. Lenses alter the path of light through refraction, which is phenomenon whereby the path of a ray of right shifts when it through materials with different density levels. Lenses are made from transparent materials, such as plastic or glass, which have been molded to give the required shape. A lens can be termed as either simple lens made from a single material, or a compound lens, which consists of an assembly of multiple lenses aligned along a common axis. Lenses are used ...

The process is also used in the development of acceptance and performance criteria that find use in the clarification of study objectives, defining of appropriate data type and the specification of potential errors of decisions that are then used as the basis for the establishment of the quantity and the quality of ...

Introduction

Osmosis is the process by which water molecules move from a region of low concentration of solute to a region of high concentration of solute through a semipermeable membrane (Van 3). Osmosis therefore can define the movement of water in and out of the cytoplasm of a cell. A solution with a higher concentration of solute molecules than that of the cell cytoplasm is said to be hypertonic to the cell. On the other hand, a solution with a lower concentration of solute than that of the cell cytoplasm is said to be hypotonic to the cell.

Introduction:

Transmission electron microscope (TEM) is the type of a microscope that uses a beam of electron rather than visible light to illuminate the specimen. Besides, while light microscope uses glass lens to focus light to the specimen, TEM uses electromagnetic lenses for focusing of the electron beam. TEM has a higher resolving power than the light microscope because the electron beam it uses for illumination has a much lower wavelength than visible light. During the operation of TEM, some electrons passing through the specimen get scattered and disappear from the beam. However, the unscattered electrons reach a fluorescence screen ...

Background about the development of a bird

The development of a bird from an egg is the complex and speedy process which takes 21 days from the moment the embryo forms. The developments are facilitated by among other factors the presence of pores (about 7,000 of them) on the egg's surface. The pores allow transfer of gasses (oxygen diffuses in while carbon dioxide and water vapor diffuse out) through the shell (Gilbert). Before the egg is laid, it is fertilized; the living cells divide and grow wile segregating into groups. During incubation, the first sign of an embryo appears at 13 to 16 hours after ...

Introduction

A turbulent jet is a source of energy and momentum in a fluid tank. A jet is considered fully turbulent at a jet laminar for Rej below about 100 and Reynolds number Rej above about 1’000 – 2’000. Therefore, the limit between a turbulent jet and laminar is around the Reynolds number of 3’000 and the significant characteristics of the jet are its discharge and momentum flux.

Eq. 2; Qj = vjAj – jet volume flux
Rej = vjdjv = jet Reynolds number
Frj = vj√g'dj = densimetric jet Froude number

Question 1

Brand positioning is essential for companies wishing to develop competitive advantage in a market. Strategies for brand positioning are based on two main platforms, competitors and consumers. Quality and price of a product are the two main attributes used for effective positioning of a product. This was also confirmed by Michael Porters when he came up with the generic strategy for competitive advantage. According to porter’s generic strategy, there are three approaches that can be applied to any product in any industry for competitive positioning in a market. The three approaches include, cost leadership, differentiation, and market focus. Differentiation entails creating a unique ...

In order to properly outline the ethical dilemmas of conducting business it is necessary first clearly define what a business is and what are the boundaries within which we want to place these ethical considerations. This is the starting point of this essay. For the purpose of this discussion we will define business as "a voluntary association of individuals, united by a network of contracts" organized to achieve a specified end. In a cornerstone article on normative theories of business author, John Hasnas, asserts that “because businesses consist in nothing more than a multitude of voluntary agreements among individuals any attempt to provide a general account ...
