All procedures were followed according to the lab manual (experiment 10 – Electrochemistry Laboratory). Data and Observations Part A: Grams of FeSO4 used: 0.759 Voltage during voltmeter and battery check: 9.23V Table 1. Electrochemical Cells Data Part B: Table 2. Lead-Acid Battery Results and Calculations In order to make 5ml of 1M FeSO4(aq) (molar mass = 151.92)‚ we calculated the needed grams according to c= n/V; 1 = n/(0.005)‚ n = 0.005. Since n = m/M‚ 0.05X151.92 = 0

immediate/unlawful contact (Darby) Battery is the actual application of force without consent‚ lawful excuse or justification At common law‚ an assault is any act committed intentionally or recklessly‚ that causes another person to apprehend immediate or unlawful violence. If force is actually applied‚ directly or indirectly‚ and unlawfully‚ without the consent of the person assaulted‚ the assault becomes a battery‚ however slight the force (Fagan) Both assault and battery are often described as ‘assault’

Creating a New Computer By: Samantha Harper 1. Subtract: I would take away the keyboard from my laptop. This feature is unnecessary and makes the computer heavier than it should be. 2. Repeat: I would keep the USB ports as a simple way to add or remove data from the device. 3. Combine: I would combine a handheld printer that can be attached to the USB port to print documents on the go. 4. Add: I would add a night vision motion sense laser to the web cam to allow the user to chat without needing

had to pay for the mobile phone and related expenses. A phone with many features and capabilities can be expensive. I had considered about size‚ battery life‚ price‚ internet access and other features. Finally‚ I had to pay about 14‚000 baht for my mobile phone. Moreover‚ a mobile phone cost a few to maintain such as screen protector‚ battery‚ battery charger and fixed if necessary. Of course‚ I had monthly phone bill. Mobile phone expenses can be controlled in limit budget. I look at my current

(Optional) After these parts of the project have been realised‚ we would enhance our project by aiming to generate electricity using this wind turbine. This would be achieved by using a trickle charge battery and an inverter to receive an A.C signal. Motivation The motivation behind this project is to generate pollution free cheap electricity. Wind is a viable option to complement other types of pollution free generation. During this project we would

Apparatus & Procedure: This experiment required the use of a 1.5 V D-size battery‚ a battery holder‚ a digital multimeter‚ a 220μF capacitor‚ a 100 KΩ resistor‚ a DPDT switch‚ connecting wires‚ alligator clips‚ and a stopwatch. After the apparatus was set up and the multimeter was connected to the capacitor‚ the first procedure required the capacitor to be charged via throwing the switch towards the battery and simultaneously starting the timer. The voltage across the capacitor was recorded
