Fluid Mechanics 3-Aerofoil Lab Report Introduction This report aims to investigate the effect the angle of attack of an aerofoil has on the air flow around it. This was done by recording the lift and drag forces the aerofoil experienced when positioned at different angles of attack. The experimental lift force the aerofoil experienced when positioned at different angles of attack was then compared with theoretical values. An attempt was made to explain any discrepancies

This causes a rapid increase in positive nerve fiber. 3. What is presbyopia? An age related disease that makes it hard to focus or see things that are close to you. 4. Distinguish between myopia and hyperopia. Nearby objects are clear but far objects are blurry and the eyeball has grown too long

Introduction “Micro” refers to tiny‚ “scope” refers to view or look at. Microscope is the major tool of biologists‚ an optical instrument that uses lens or combination of lens to produce magnified images that are too small to seen by unaided eye. Microscope provides the enlarged view that helps in examining and analyzing the image. Through the use of microscope ‚ knowledge of cell structure was gained and one of the fundamental theories of biology‚ the Cell Theory was developed.

CHAPTER 1 : A LOCAL ECOSYSTEM What is an ecosystem? Characteristics? The size of a population of organisms? Factors for this variation? Environmental factors? An ecosystem is any environment containing living organisms that interact with each other and with the non-living parts of the environment. Largely self-sustaining. - materials and energy are exchanged via food webs. - any size. (eg. a pond‚ a forest‚ a desert or a piece of bushland.) Does not
