Theory behind my experiment Thickness (cross sectional area of the wire)‚ length‚ and temperature all have some effect on the amount of resistance created in a wire. Another factor is the conductivity of the material we are using. Some metals are just more electrically conductive than others. As long as I use the same type of metal for each wire‚ my experiment will remain fair. Cross Sectional Area The thicker the wire‚ the less resistant it is. This is because there are more electrons

GCSE Astronomy Controlled Assessment: B4 – Constellation Photography Design For my coursework I have chosen to attempt photography of three different constellations in the night sky. I will go out on three separate dates to take photos then select the best photographs to use for the analysis. I will then aim to identify colours and magnitudes of my photographed stars using comparisons with reference stars for which I have collected known magnitudes from official sources.

My hospital bed was ice cold and the bleak and empty white walls depressed me as the uncomforting thought that I would have to stay here for maybe another week brought tears to my eyes. The usual and oppressive smell of disinfectant lingered in the room as I recalled that night in my head‚ trying to convince myself it wasn’t my fault‚ as I had done everyday since the accident. It was the day everything changed and my life was turned upside down. Forever. Provocatively decorated caravans snaked to

easier for us to record our results. These are the results we got from our preliminary experiment: Length (mm) +/- 1mm | Diameter (µm) +/- 1 µm | Resistance (Ω) +/- 0.1 Ω | 200 | 30 | 1.2 | 200 | 45 | 0.8 | There were uncertainties in our experiment. Diameter = 3.3% for 30 µm 2.2% for 45 µm Length = 0.5% Resistance = 8.3% for 1.2 Ω 12.5% for 0.8 Ω Evaluation of our Preliminary Experiment The whole point of our preliminary experiment was to see after doing it

The factors that affect the motion of a falling object Scientific Knowledge When an object falls‚ many forces are acted upon it: gravity‚ friction‚ air resistance and‚ if in the water‚ up thrust. When an object starts to fall‚ gravity over powers air resistance‚ however‚ as an object starts to reach terminal velocity (its maximum speed) the opposite forces start to even out until they are equal. Some people believe that if the forces are balanced then the object has stopped moving‚ meanwhile they

1. I believe that this bag is the most appealing and suitable bag both for my client and punk theme. The size of this bag is perfect for my client‚ also it can be held as both a side bag and a hand bag‚ which were both my clients’ first choices. Also the bag is very interesting‚ simple and appealing‚ as it only contains two simple colours‚ but also has badges to make it look punky. Also this bag contains secret pockets both inside and outside the bag to keep the very important personal belongings

of the turns in the coil add together‚ so the total magnetic field is much stronger. This produces a field which is similar to that of a bar magnet. A coil of wire like this is often called a solenoid. http://www.bbc.co.uk/bitesize/standard/physics/using_electricity/movement_from_electricity/revision/1/slideshow-1/2/ An electromagnet consists of a coil of wine‚ through which a current can be passed‚ wrapped around a soft iron core.
