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

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

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

A negative charge because when it is negatively charged electrons are added to the penny. 17. What is the voltage at the location of a 0.0001 C charge that has an electric potential energy of 0.5 J (both voltage and potential relative to the same reference point)? Potential = energy Charge = 0.5 J / 0.0001

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

With the abundance of social issues included in The Wire‚ some may find it surprising how there is still room for a “vast and complex social network” of characters (Potter198). The show switches the narrative point-of-view often between the police‚ politicians‚ drug dealers‚ corner kids‚ teachers and other

We varied both the accelerating force and the mass of the glider. We found that for a given force the acceleration of the glider was inversely proportional to the mass of the glider

In episode 3 of The Wire‚ there are a lot of characters that seem to know nothing more than selling drugs and making money. However‚ in this scene starting at 10:41 and ending at 12:41 shows that these characters are bit more complex and two sided than we are shown. This scene starts with a very fast pan of the pit area until the camera finds D’Angelo. This pan of the courtyard shows how unsafe it is‚ and how the characters are being watched and how they should watch their backs. The pan of the
