    Peaceful resistance to laws positively impacts a free society. In our world‚ civil disobedience is important in showing mass beliefs of all people. If any person doesn’t agree with a law‚ they should have the right to peacefully resist the law as long as they accept the consequences. Resistance that is not peaceful is the problem in today’s society and causes tension between people and the law. For example‚ Rosa Parks is a name that is important in history and will never be forgotten. “You must never

    Peaceful resistance to laws doesn’t have to have either a positive or negative impact on a free society. To me a free society is about society expressing themselves without being judged by what they might think. For example‚ In the Constitution (under the Bill of Rights)‚ the First Amendment says " Congress shall make no law respecting an establishment of religion or prohibiting the free exercise thereof‚ or abridging the freedom of speech or of the press‚ or the right of the people peaceably to

    Current is a flow of electrical charge carriers‚ usually electrons or electron-deficient atoms. The common symbol for current is the uppercase letter I. The standard unit is the ampere‚ symbolized by A. One ampere of current represents one coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second. Physicists consider current to flow from relatively positive points to relatively negative points; this is called conventional current or Franklin current. Electrons

    HOOKE’S LAW EXPERIMENT Aim: The aim of this experiment is to determine the force constant (k) of the particular spring used. Introduction Hooke’s Law: Hooke’s Law is a law that shows the relationship between the forces applied to a spring and change in its length (extension). The relation is best explained by the equation: F= -k Δx F: Is force applied to the spring this can be either the strain or stress that acts upon the spring. k: Is the spring constant and details how hard

    Becca DeHaven ChemC-125 Avogadro’s Law Experiment Report Introduction: The following experiment’s purpose was to confirm Avogadro’s Law and experimentally determine the Universal Gas Constant “R”. Amedeo Avogadro hypothesized that all gases of equal volume‚ temperature and pressure would contain equal amounts of moles. This idea that volume is directly proportional to moles sprung from other similar hypotheses. Robert Boyle found that pressure and volume are inversely proportional‚ meaning as pressure

    Boyle’s Law Experiment Aim To show that Pressure is proportional to the inverse to volume Method A gas syringe was attached to a pressure sensor. The pressure sensor was calibrated‚ assuming the atmospheric pressure at the time of the experiment was 100kPa. Differing volumes of gas were created in the gas syringe and they were recorded as were the corresponding values of pressure at that particular volume. The volume was varied between 20cm3 and 75cm3. Results A set of readings was obtained

    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

    Physics Coursework Objective: My objective in this experiment is to investigate one of the factors that affect the resistance of a piece of wire; the one I am investing is the length at constant temperature. My objective in this experiment is to investigate one of the factors that affect the resistance of a piece of wire. The factor I chose was length. Factors: There our four different things that affect the resistance of a wire: 1. The Length – because the wire is thinner than the
