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

African American community‚ during a time of what we call the Civil Rights Movement. Many actions had to take place in order for the black American’s to feel as though they mattered and contributed to the economy as much as white Americans. Civil resistance‚ boycotts‚ petitions‚ sit ins‚ inner city riots‚ freedom rides‚ voting registration organizing‚ and march’s were all well strategized actions leading to great results that the African American into today’s society can enjoy living the America Dream

ELECTRICITY I. DISCOVER OF ELECTRICITY About 600 B.C.‚ Thales‚ a Greek philosopher and scientist‚ observed that a piece of amber attracted small bits of “paper” or very thin wood shavings after it was rubbed with wool. He had discovered‚ in effect‚ static electricity. William Gilbert‚ an English scientist in the sixteenth century‚ found that many other different materials could be made to act like amber. Whenever these objects were rubbed against each other‚ they were able to attract each other

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
