An Investigation Into The Resistance Of Conductive Putty
Primary Work
In this experiment I will be using conductive putty for the first
time. I do have knowledge of electrical circuits such as parallel and
series. I have knowledge of electrical equipment like bulbs, battery
cells and variable resistors. And I have knowledge of the circuits'
advantages and disadvantages. My plan is to use the putty in a series
circuit with an ammeter and record the currant.
Prediction
==========
I believe that the shorter the piece of putty the stronger the currant
will be. I believe this because I have found that electrons always
take the shortest route.
Apparatus
In this experiment I will need; a light bulb, a light bulb holder, a
battery pack, four crocodile clips, an ammeter, a power supply, a
piece of putty and four wires. I will need the light bulb to show if
the circuit is complete. The battery pack is control the electrical
currant and the crocodile clip and wire to carry the currant.
Safety
The first danger is the power of the electrical currant. To prevent
any danger of electrical shocks I will use the battery pack to control
the strength of the currant and turn it down to four cells. The power
will be DC (direct currant) and the putty used will be on a
non-conductive surface.
What factors could affect what happens
There are two obvious factors what come to mind and that is inaccurate
measuring and uneven amount of putty. I will have to be careful with
the measuring of the putty and the amount removed each time.
What I am going to change
In the experiment I am going to keep the putty's diameter the same but
change the length each time and record the amps with each reduction in
the putty.
What I will measure in
I plan to measure the putties length and diameter in centimetres and
the currant in amps.
What factors I am going to keep the same
Now that you have an idea on the parts and tools needed for the conversion, it's time to...
I then figured out when, what and where our lights were going to be on, off and what colour. Also sounding and V.O cues.
First he would select some people from the audience to inspect the apparatus. It was just a tall cabinet with a truck inside. The inspectors would knock on all of the sides and look inside. After they approved, Houdini would hand them a black bag and some tape. They would tie his hands together and helped him into the bag and shut it as tightly as they could, following his instructions. Then he was placed into the trunk and the trunk was locked, tied securely, and placed inside the cabinet as well. After all of the steps were completed Bess would close the curtain and say “I shall clap my hands three times, and on my last clap I ask you to watch...closely…” then she would step behind the curtain and not three seconds later the curtain would snap open, but it wasn’t Bess that you saw….it was Houdini! Then Houdini would turn to the trunk, that was still sealed shut, he would untie the ropes and unlocked the trunk to reveal the bag. When he opened the bag Bess was inside tied the same way that Harry had been! Although this isn’t the trick made the Houdini’s as famous as Harry wanted them to be (Sutherland). Harry Houdini once said: “No performer should attempt to bite off red-hot iron unless he has a good set of teeth.” Let’s just say that he had an amazing set of
Slide the power supply to the rear of the computer case; line up the holes in the unit carefully with the holes in the outside of the case.

I am writing to you to share the work I have done on the project and have decided to make the marketing plan for the formerly popular Etch-A-Sketch toy. I will identify our target market, and outline our objective and the 4 Ps of marketing

Being poor, Morse used materials like an old artist's canvas stretcher to hold his invention, a home-made battery and an old clock-work to move the paper on which dots and dashes were to be recorded. In 1837 Morse got two partners to help him develop his telegraph. One was Leonard Gale, a quiet professor of science at New York University, who taught him how to increase voltage by increasing the number of turns around the electromagnet. The other was Alfred Vail, a young man who made available both his mechanical skills and his family's New Jersey iron works to help make a better telegraph model.... ... middle of paper ...
Iron nail (1) Paperclips (several). Power supply (1) Coil (1) Method: - - - The method is relatively systematic. We first allocated various people amongst our group to collect different equipment such as the iron nails, paperclips, coils and power supply. Following that, we connected everything securely and wrapped the coil five times around.

Investigatiing Whether the Thickness of Lead Inside a Pencil Affects the Resistance Aim The aim of this investigation is to find out whether the thickness of a lead inside a pencil affects the level of resistance when connected to and electrical circuit. Prediction I think that lower resistance will be shown in the results from pencils with thinner lead because the current will ba able to pass through the lead easier. Preliminary Test Our preliminary test was for the purpose of finding out whether doing the investigation in different ways would affect the results. We started with putting a high current through a pencil first, taking our results, and then lowering the voltage. Then we did the opposite, starting with a low voltage, taking our results, and re-testing with a higher voltage.
In the article, “A randomized trial of traditional and golf-specific resistance training in amateur female golfers: Benefits beyond golf performance” the authors compare the impacts of golf-specific resistance training (GSRT) to the traditional resistance training (TRAD) to establish whether physical exercise has any impact on golf outcomes. Dr. Hegedus based this study on the discovery from previous literature establishing resistance training does benefit performance in golf. This research used a comparison method between the traditional resistance-training program and a golf specific program to investigate the effects of a 10-week training program on golf performance on amateur female golfers. The speed and driving

The measure of the ability of an electrolyte solution to conduct electricity is called its conductivity. Conductivity is also referred to as specific conductance. The SI unit of conductivity is siemens per meter (S/m).
