An Investigation into Factors Affecting Resistance of a Wire Plan: The possible variables I could use to find out factors affecting resistance are material wire is made of, length of wire, temperature and cross sectional area of wire. I will use cross sectional area of wire and length of wire because I think it will be hard to draw conclusions from the material of wire. I am not doing temperature because it would be hard to get results from and I think they wouldn't be as accurate.
Factors Affecting the Resistance of a Wire The aim of this experiment is to investigate one factor that affect the resistance of a wire. I will do this by performing an experiment. First I will need to identify the factors that effect resistance. There are a few factors that affect the resistance, it is determined by the properties an object has. This is know as resistivity. The factors I can investigate are : Ÿ Temperature Ÿ Length Ÿ Cross-sectional area/width Ÿ Material
of the Wire Affects the Resistance of the Current Passing Through Wire Aim For this experiment, my aim is to investigate how the length of the wire affects the resistance of the current passing through the wire. Hypothesis and Scientific Knowledge When electric current passes through a conductor, there is always a resistance against it. The resistance varies between different types of materials. Although all metals are conductors, some have a higher resistance than the other. For example
Factors Affecting the Resistance of a Metal Wire 1. Investigate some of the factors that affect the resistance of a metal wire. The current and voltage will be measured and then V = IR will be used to calculate the resistance. The potential divider circuit produced better results in the investigation into how resistance depends on the number of identical resistors connected in series, so this circuit will be used for this investigation, too. Variables and Constants 2. Possible
Factors Affecting Osmosis The aim of this experiment is to investigate the factors affecting osmosis. I have chosen to investigate the effect varying concentration of sucrose solution has on the amount of osmotic activity between the sucrose solution and a plant cell. The plant cell I have chosen to use is a potato tuber from which I plan to cut potato chips of equal length which I will place in test tubes filled with varying concentrations at equal volumes of sucrose solution. After a
The Factors Affecting Osmosis in Potato Tissue Planning In this coursework I am investigating the factors affecting osmosis in potato tissue. [IMAGE] Osmosis is defined as the net movement of water molecules from a region in which they are highly concentrated to a region in which they are less concentrated. This movement must take place across a partially permeable membrane such as a cell membrane, which lets smaller molecules such as water through but does not allow bigger molecules
Factors Affecting Osmosis in Potato Tissue Introduction: I am going to design and modify an experiment used to show osmosis in potato chips in different concentrations of sucrose solution. I am also going to investigate on how potato chips change in volume and weight when placed in different concentrations of sucrose solution. I will also conduct a preliminary experiment before my final experiment. Aim: To investigate the effect of different concentration of sucrose solution on potato

Antibiotic resistance is a phenomenon in which microorganisms undergo a genetic mutation that allows them to withstand the effects of antibiotic agents designed to kill them or make them incapable of reproduction. To understand antibiotic resistance, it is important to understand what antibiotics are and the mechanisms behind these drugs that affect diseases. Antibiotics are chemical agents that specifically target certain bacterial strains and disable the bacteria by preventing their reproduction
We the Students Essay LESSLY DIAZ 1ST Does peaceful resistance affect society negatively or positively? In this last year’s we’ve seen several peaceful resistance against the law like for an example people protesting against the presidential election. Peaceful resistance has affected the society in a positive way it has affected the society in such a positive way because people have the freedom to express their feelings, thoughts, and opinions
The Length of a Wire and Its Effect on Resistance Introduction: In an electrical circuit, the current (flow rate of charge) depends on the battery voltage that causes the charge to flow through the circuit and the components in the circuit. A circuit consists of a bulb, a battery and a resistor. The bulb is like a resistor, it slows down the electrons and the battery pushes the electrons and gives them energy. A component is a resistor, it slows down the flow of electrons. The bulb
cause a minor or major hormonal imbalance. Hormonal imbalance can affect the human body in multiple outcomes. Pesticides and herbicides have chemicals that leave residue in the produce even after they have been washed. Also, growth hormones are affecting children by causing early puberty in young girls as well as young boys. Accordingly, hormones used in meat and chemicals used in fresh produce affect the human body by creating a hormonal imbalance that can induce early puberty in young girls and
Resistivity of a Wire Aim The aim of this experiment is to find out how the area of the cross section of the wire affects the resistance and also to find out the resistivity of the wire having found the resistance over a certain length and using a certain cross sectional area.

Theory This information was taken from the Collins advanced science Physics textbook, the Cambridge Advance Science Physics 1 textbook and from notes taken in class. E.M.F or Electro Motive Force is the opposite of potential difference, in that; it is the situation where a voltage is gaining energy. This seems
Gravitational Pull and Parachute Investigation Aim The aim of the experiment is to investigate how each of several different weights of varying mass attached to a parachute in turn can influence the gravitational pull and air resistance forces acting on it, consequently affecting the time it takes to reach the ground when dropped from a specific height. Preliminary Work Forces are measured in Newtons (N), named after Isaac Newton who invented this unit. We cannot see them but instead we can
unnecessary intake, factors exist which can contribute to halting this increase. Phage therapy should be implemented into Western healthcare as a replacement or safety net for antibiotics because such techniques have the potential to diminish antibiotic-resistance. The Center for Disease Control and Prevention states that over 2 million United States citizens are infected
Antibiotic resistance is one of the most important issues facing health care today, with wide reaching future implications if abuse continues. In the United States alone, antibiotic resistance is responsible for over two million illnesses and 23,000 deaths per year. Providers need to be judicious in the disbursement of these life saving pharmacological agents, while being informative of why antibiotics are not always the answer (Talkington, Cairns, Dolen, & Mothershed, 2014). In the case listed
Science Coursework The Resistance of a Wire Aim: To find out how the length of a wire affects the resistance of it. Knowledge: Ohms Law is a mathematical equation that shows the relationship between Voltage, Current and Resistance in an electrical circuit. It is stated as: , V = I x R , R = V / I , I = V / R Where · V = Voltage · I = Current (I stands for INTENSITY) · R = Resistance In order to understand what Ohms Law is all about you need to understand electricity
