Lab 1: Flame Test 11 Chemistry‚ university Preparation Conducted: September 20th‚ 2010 Purpose: To observe‚ and create a chart of the colours produced when solutions of known metal compounds are heated to high temperature. Question: What colours are produced when different metallic compounds are placed in a flame‚ and why this happens? Hypothesis/Prediction: Different salts will produce different colours when placed in a flame‚ due to the fact that each element has a different

The Gold Rush Of 1849 Would you travel‚ live‚ and work under harsh conditions for months to fulfill a dream? Thousands of gold hunters from all corners of the world did so in hopes of striking rich after a brief discovery of gold in the American territory of California. This huge worldwide flock of people became known as the California Gold Rush of 1849. The Gold Rush granted riches to and a handful of miners‚ but provided Americans as well as many foreigners a new homeland and life. At the start

The Decision Making Process Jenna Abstract As a senior‚ the decision on whether or not you want to go to college comes out being the hardest decision some students make. I have made the decision that I want to go to college. Going to college will get me where I want to be. Not only that‚ but it will further my education. The decision that I need to make is whether or not I want to play volleyball in college or not. Colleges have given me several opportunities to

substance whose resistance almost remains unchanged by increase of temperature. 2. Name two special characteristics of heater coil. 3. A wire of resistance 4 ohms is bent to form a circle. What is the resistance between two diametrically opposite ends? 4. How does the resistance of a conductor change if its temperature is increased? 5. A current of 4A flows in a wire of resistance 60 ohms. Calculate electrical energy consumed in 2 minutes. 6. V-I graph for two resistors is given. Which of the two has

simultaneously on different channels (wires‚ frequency channels) within the same cable‚ or radio path‚ and synchronized to a clock. Parallel devices have a wider data bus than serial devices and can therefore transfer data in words of one or more bytes at a time. As a result‚ there is a speedup in parallel transmission bit rate over serial transmission bit rate. However‚ this speedup is a tradeoff versus cost since multiple wires cost more than a single wire‚ and as a parallel cable gets longer‚

For each case‚ find the direction of the magnetic force acting on the wire. 7. In Figure 2‚ assume that in each case the velocity vector shown is replaced with a wire carrying a current in the direction of the velocity vector. For each case‚ find the direction of the magnetic field that will produce
