Genre 1: Tap Tap is an artistic form of dance performed today‚ it includes a metal plate on the toe and heel of the shoe which makes tapping sounds. Tap has two historical links in Ireland and Africa. They were brought over to the United States through immigration and slavery. In mid 19th Century‚ Irish would ‘blackface’ and perform imitations of slaves as a form of comedy‚ mimicking shuffling and chugging movements. They started performing on stages which started the origin of tap. Tap started as

Practical Investigation Resistance in Wire Aim: To investigate if the length of wire affects its resistance and find out how the resistance changes when the length of wire increases. Hypothesis: My prediction is that as the length of wire increases‚ the resistance will also increase. This is because current is the flow of electrons in a circuit and voltage makes the electrons flow through the circuit. The electrons have to collide with the atoms in the wire‚ which makes the electrons harder to

because the electrons would bump into more atoms‚ the longer the wire which is like using up its fuel. Material – different materials inherent resistances as they have more or less atoms in them already. Thickness – Thickness affects resistance because the thicker the wire the more paths the electrons have to avoid the atoms. Therefore the cross sectional area is larger so there is less resistance. Temperature – The hotter the wire is the more energy the electrons have to flow faster. Why do we

affects the resistance of a wire. Reworded: I am going to investigate if changing the length of a wire changes its resistance. I predict that the longer the wire‚ the more resistance it has. Planning and Preparation Independent Variable: The variable I changed was length (cm). Dependent Variable: The variable I measured was resistance (Ω). Fixed Variables: The variables I kept constant to make it a fair test; were‚ the type of wire (nichrome)‚ the thickness of the wire‚ and the temperature of the

Problem Does temperature affect the resistivity of different sized copper wires? Hypothesis I think that the resistivity will increase with higher temperatures because with higher temperature‚ resistivity is higher due to the fact the atomic lattice structure increases. Background Electrical resistivity is the measurement of how a material opposes the flow of an electrical current. On the other hand‚ electrical conductivity () is the inverse of resistivity. It is the measurement

RECENT TRENDZ IN POWER GENERATION POWER GENERATION FROM ROAD SPEED BREAKER AND FROM SHOES (Recent way to produce power) ABSTRACT: Man in his lifetime‚ uses energy in one form or the other. In fact whatever happens in nature‚ results‚ out of the conversion of energy in one form or the other? The blowing of the wind‚ the formation of the clouds and the flow of water are a few examples that stand testimony to this fact. Of late‚ erratic and perfunctory usage

Benefits of Network video surveillance What is an Analog Video Security System? Cameras on a modern analog CCTV system send their video over co-axil cabling back to a digital video recorder (DVR). Most modern DVRs are a network device‚ and as such can be accessed remotely from the LAN‚ or with the proper configuration‚ from across a WAN or the internet. Video is kept on hard drives‚ typically on a FIFO basis so there is always a rolling video archive of the past X number of days. What is an

In Reaction 1‚ the mass of the pre-cut copper wire was measured with watch glass on the analytical balance‚ the mass was recorded using as many significant figures as possible on Table 2. The copper wire was bended into a circle and laid flat on the bottom of the 250 mL beaker. Inside the fume hood‚ 4mL 16M of HNO3 was added into the 250mL beaker that contained the copper wire. The copper wire was completely dissolved by swirling the beaker. The observation was recorded in Table 3. For Reaction 2
