Planning In this piece of coursework‚ I am going to investigate what affects the resistance of a piece of wire. Wire is made up of atoms. Electric current is a flow of electrons‚ and it is these electrons that collide with the nucleus of the atoms. Every time this happens‚ it causes resistance. The build up of friction is what produces the heat. There are many variables that could affect the resistance of the piece of wire: Length Potential difference Tension Temperature Diameter

Peaceful resistance‚ as with all forms of protest‚ have both positive and negative effects on America’s concept of a “free society” but upon inspection‚ one can see that in time‚ it is positive. Forms of peaceful resistance can range from a conscientious objection to a law in the form of protesting‚ to simply writing a representative to express one’s opinion on a law. Each of these are opportunities for citizens to exhibit their constitutional rights to organize‚ free speech‚ and perform their civic

Current and Resistance Physics Investigation Aim: Investigate how the length of a wire affects the current and resistance of a wire. Prediction and Hypothesis: I think as you increase the length of the Constatan wire‚ you also increase the amount of resistance. The current is the flow of electrons; the current is dependent on the amount of voltage‚ which is applied. Voltage is the push given to the current. The current has to go through a circuit‚ which contains resistance so if you increase

surviving the many hardships they were presented with. In “The Diary of Anne Frank” and “Resistance During the Holocaust”‚ it explains how individuals would use different methods to passively resist. As a response to conflict‚ people passively resisted by maintaining hope‚ preserving culture‚ and providing safety. Many Jews in ghettos and death camps would passively resist by maintaining

Peaceful resistance has a positive impact on a free society. The best way to get things accomplished is to make your voice heard and to fight against topics you feel are unjust. However‚ the main component to being successful is keeping it peaceful. Too many times‚ people protesting get violent and take it too far. With the recent election of Trump‚ there have been riots with people harming others‚ burning buildings‚ and smashing windows. This has done nothing but make a common political party turn

While Duncombe talks extensively about the various types and stages of cultural resistance‚ the overall idea is to rebel against an overarching societal system that is oppressive in some manner. This resistance can be presented through arts and media‚ action‚ or personal attitude. The author believes that any movement of this nature against the norm can create new school of thought on one end and a full-blown revolution on the other. Duncombe begins his piece by stating his observations of the rave

Causes of antimicrobial drug resistance Microbes‚ such as bacteria‚ viruses‚ fungi‚ and parasites‚ are living organisms that evolve over time. Their primary function is to reproduce‚ thrive‚ and spread quickly and efficiently. Therefore‚ microbes adapt to their environments and change in ways that ensure their survival. If something stops their ability to grow‚ such as an antimicrobial‚ genetic changes can occur that enable the microbe to survive. There are several ways this happens. Natural (Biological)

or we hear it at school‚ resistance it seems to be happening more and more these days. Most of the resistance that I have seen‚ watched‚ or heard about lately has been centered around our new President‚ Donald Trump. Most of these protest or resistance to laws or resistance to change or even resistance to changing the laws‚ there have been no in-between on sides or passion. We have either seen peaceful resistance or an all outright very violent and destructive resistance. Both sides‚ peaceful &

Bio-112 Antibiotic Resistance Experiment Lab Partners: March 10‚ 2010 When we initially started the bacteria antibiotic experiment on February 10‚ 2010 our team selected e-coli and Rifampicin (Rb5) to find out the level of resistance e-coli would build towards this antibiotic. When we first checked our agar dish on February 15‚ 2010 we noticed two circles for the zone of inhibition the small circle was 1.5 cm and the medium circle was 3.00 cm. Two days later when we checked
