Physics 1408 Section E1 Standing Waves in a Vibrating Wire Callie K Partner: Miguel E Date Performed: March 20, 2012 TA: Raziyeh Y Abstract This lab had two purposes. The first was to determine the relationship between the length of a stretched wire and the frequencies at which resonance occurs. The second was to study the relationship between the frequency of vibration and the tension and linear mass density of the wire. In the first part we found the resonance, frequency and wavelength of a wire and used this data to calculate the speed of the traveling waves. For first harmonic, our wavelength was 1.200 m, found by the formula λ=2L/n.

Coaxial cable- For the COAXIAL CABLE I would do the same first few steps by getting the correct length of cable that I would need. Then you would use the cable stripper and stripe off just over a half inch of the outer jacket. I would then insert the center conductor into the center pin. I would crimp the pin twice with a ratcheting crimper. I would then put the connector onto the end of the cable.
If they don't line up, pull them out and line up. Do this carefully, as it's the last step before crimping on the connector. Step 8: Carefully insert the connector and cable into the crimping tool, which has two dies that will press into the connector, and push the pins in the connector into the conductors inside the connector. Now the installation is done. After the whole installation, you should check to ensure all conductors are making contact and that all pins have been crimped into their respective conductors.
Dr Khounsary explains an experiment using a fixed voltage and varying the temperature of the wire using a torch. The article further explains that the temperature coefficient of copper at 20 degrees C is .00393 and that a single degree of temperature change would increase the resistance of the wire by that amount. In the article regarding the Effect of Temperature on Conductivity (The Nuffield Foundation, 2006) the article describes how the conductivity of a wire decreases as it is heated. It provides an example schematic diagram for the test circuit and the use of Eureka wire instead of copper wire. A2a.
Carefully insert the connector and cable into the crimping tool, which has two dies that will press into the connector, and push the pins in the connector into the conductors inside the connector. Now the installation is done. After the whole installation, you should check to ensure all conductors are making contact and that all pins have been crimped into their respective conductors. If the connector didn't crimp properly, cut off the connector and redo it. For a coaxial cable, adjust the coaxial cable wire strippers so the first cut is down to the center copper wire.
7. You want to build a circuit which causes a ligh tbulb to turn on when you throw a switch. So, you build the circuit if Figure 5. When the switch is connected to point A the capacitor charges, and when you connect the switch to point B the light goes on. Let the resistance of the light bulb be Rℓ = 1.50 ×103 Ω, the potential difference across the battery is VB = 10.0V , and the capacitor has a capacitance of C = 1.35 × 10−4 F
Technically, electricity is created by particles that carry a charge, usually electrons. In a wire or any other conductor, electrons move freely around the stationary atomic nuclei making up the conductor. Electrical current is the movement of these charged particles. In most conductors, the flow of electrons is impeded by some resistance, which can be thought of as collisions of electrons with the nuclei or other electrons. This creates an atomic-level "friction" which produces heat (and light in some cases, such as a light bulb or glowing heater element).
How does the rate of reaction in Task 2 compare with the rate in Task 1? Suggest a reason for the change. By comparing the two curves and the times taken to reach 0.0 g (the last times on the list), predict the time it would take for the reaction to finish if 100 chips were used. Task 3 Press back but not clear and change the number of chips to 100 but leave the acid concentration at 1.0 mol/dm3 . Click start and take readings as often as possible (by clicking the take readings button) until the mass reaches 0.0 g. Stop the reaction immediately.
The panel that converts light energy into electrical energy is called a Photovoltaic panel. Light energy is not only used industrially and privately, but some of our vehicles run on part solar electric or entirely on solar electric. The light energy is collected through a panel on the vehicle, which is transferred to electrical energy that hits the motor; the motor then converts the electrical energy into mechanical energy, which turns the drive shaft that turns the wheels (kinetic energy). Not all energy transfer is perfect, there will always be a loss of energy in any system. The loss of energy will come from the electrons passing through any wires, released as heat energy.
