Air resistance is an opposing force often known as drag force. Air resistance acts in the opposite direction to snow skier’s velocity and can either harm or enhance performance of the athlete. The flow of air around an object causes the unavoidable effect of drag and is influenced by the size‚ shape‚ surface‚ and overall speed of an object (John Polson‚ 2013). Air resistance is present in snow skiers and can inhibit their performance in a race greatly if the proper precautions and positions are

Task To investigate how the resistance of a wire is affected by the length of the wire. Theory What is resistance? Resistance is a force which opposes the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit. The circuit itself can resist the flow of particles if the wires are either very thin or very long. e.g. The filament across an electric light bulb. How is it measured? The resistance of a length of wire is calculated

of Silver Nanoparticle Action in Bacteria and Potential for Bacterial Resistance The antimicrobial activity of silver in general‚ and of silver nanoparticles in particular‚ is of significant interest because it appears to be independent of the strain of bacteria. Crucially‚ antibiotic resistant strains‚ MRSA (methicillin‚ or multiple-resistant Staphylococcus aureus)‚ E. coli O157‚ and others are affected by silver [6]. The reasons for this are not fully clear as yet‚ but could be related to mechanisms

There were many resistances from slaves‚ violent and non-violent‚ during the period of slavery in the BWI. Violent resistance was in the form of revolts and rebellions and non-violent resistance included actions such as suicide‚ poisoning‚ avoiding work and maroonage. However‚ there were three violent resistances which stood out. These three were Bussa Rebellion in Barbados (Easter 1816)‚ Demerara Revolt in Guyana (August 1823) and the Sam Sharp Rebellion in Jamaica (December 1831). These rebellious
