Procedure and Analysis: The lab began with the group making a rough estimate of the force required from each arm to lift the weight up to be about 700N per arm. We then drew a force diagram for the force acting on the barbell and when the lifter held the barbell over his head. Were: B= the angle=35 degrees Fn= The normal force m= mass g=gravity F= the force exerted by each arm We then used the following equation W = mg to calculate the weight of the barbell. Were: W= weight

Chris Wiginton IS-3120 Lab 5 Questions and Answers 1. A Wireless LAN or WLAN provides wireless network communication over short distances using radio or infrared signals instead of traditional network cabling. 2. Three advantages of WLAN are: a. Provides more capability than wired 10/100 Ethernet connections‚ allowing enterprise applications to be mobilized thus increasing productivity. b. Provides mobility and availability‚ in order to hook up to the network‚ you only need to open your laptop and

LAB 7: SECURITY BASIC Task 1: Hardware firewalls are integrated into the router that sits between a computer and the Internet. They typically use packet filtering‚ which means they scan packet headers to determine their source‚ origin‚ destination addresses and check with the existing user defined rules to make an allow/deny decision. . Speed: Hardware firewalls are tailored for faster response times‚ so it can handle more traffic loads. Security: A firewall with its own operating system is

This is most easily done by first identifying the strong acids that have the lowest pH‚ the strong bases that have the highest pH‚ and the neutral solutions that have a pH near 7. The weak acids will have a pH between

In conclusion to the distillation lab‚ I think our data shows that our experiment went well. Our graph resembles the graph in the lab handout (graphs attached to lab notebook sheets). The fractional distillation shows the sharp slope between when the cyclohexane burns off and mostly only toluene remains. The microscale graph seems to be accurate because it shows the large jump where the cyclohexane is burned off. To view the apparatuses used in the experiment look at the attached pictures. To
