Batteries‚ Resistance and Current “Battery-Resistor”: Check “show battery” and “show cores”‚ watch what happens‚ adjust some variables 1. Why do electrons (blue dots) move? Draw a diagram of the battery‚ label the flow of electrons. The flow of current (+) is opposite; draw this and note if toward or away from + terminal of the battery. The blue dots indicating the electrons move because there is a voltage across the battery in which the electrons flow away from the positive terminal

An experiment to investigate the factors which affect Resistance in a wire What is resistance? A potential difference (V) applied across a wire of length (l)‚ there is in the conductor‚ an electric field (E). In this electric field the free electrons are not however under continuous acceleration (Ee/m). This is because they repeatedly collide with the moderately massive vibrating atoms losing their kinetic energy. The vibrating atoms having gained this kinetic energy now vibrate more. The resulting

three years of experience. I run the sectionals at each practice conducting and helping with fingerings‚ rhythms‚ and overall sound. My section is not afraid to ask me questions and i usually ask them if there is anything they need to go over. Not only do I run sectionals for marching band but I have also taken the initiative to have sectionals for concert band as well. Although it is not a requirement for my grade and also was not asked of me‚ I would have sectionals with the students from concert band

* I will make sure I have a clear space to work in and nothing on the floor around me. In this investigation‚ I will set up a simple circuit to be able to read the voltage and current when the length of wire changes‚ so I then can work out the resistance. I will be using constantan wire starting of with 1m length and then decreasing it by 0.10m intervals down to 0.20m long. I will not go above 1m or below 0.20m because it may be too long that they resist so much current that the wire burns‚ or the

Development Cross-sectional and Longitudinal Studies: A Comparison Much of adolescent development directly correlates to the social interactions between adolescents and the people with whom they spend the most time. It is therefore logical to explore the relationship between adolescents and their families to better predict their behavioural development. When conducting developmental research there are two most established ways of studying the subject population. The first is a cross-sectional study

Background Information Surface area will increase the speed of reaction as the greater the surface of the solid reactants‚ the more particles are required to expose and ‘cover’ the capacity of the solid. Increased surface area results in an increased chance of collisions between reactant particles. Since the collisions become more frequent and abundant‚ the rate of reaction increases. Aim The aim of the experiment is to see if a greater surface area of a dissolvable tablet creates a faster or

type B pencil had the highest resistance and type 11B pencil had the lowest resistance. B type pencils are darker than H type pencils. For B type pencils‚ the pencils get softer as its number increases. For example‚ a 6B pencil is softer than a 4B pencil. It was evident from the data that softer pencils have a lower resistance. For instance‚ the average resistance for a one centimeter line for a B type pencil was 0.275 MΩ‚ but for a 11B type pencil the average resistance decreased to 0.084 MΩ. In addition

SECTIONAL AND SELF BALANCING SYSTEM Introduction: After the transactions‚ being recorded in the journal‚ are classified in the ledger. A small enterprise normally has less number of accounts are therefore can maintain all the accounts in one ledger alone. However‚ in case of a big enterprise‚ the number of accounts are large and‚ therefore‚ it becomes inconvenient to maintain all accounts into one ledger alone. Hence in such a condition the ledger is sub-divided into the following three ledgers:

Slavery: A Sectional Issue From the time of the first exploration of the New World to the eve of the Civil War‚ slavery played a significant role in the development of the United States. Before the American Revolution‚ the North and South both practiced slavery. Whether the first African Slave trade between England and the West African Coast‚ or the last slave trade where Virginia and Carolina profited by selling slaves to the black belt states‚ slavery was a dominant presence for nearly

Impact of Peaceful Resistance I think that peaceful resistance impacts society in a positive way. The reason I think this is because the society we live in nowadays shows us that theres a specific way to act or to follow certain beliefs in order to fit in. If people stand up for something they believe that the government is doing wrong then they will show others that it is okay to speak their mind without causing violence. Many people in our history have done this and changed the world.
