The TLV-TWA for hydrogen sulfide gas is 10 ppm. Hydrogen sulfide gas is stored in a tank at 100 psig and 80 degrees F. Estimate the diameter of a hole in the tank leading to a local hydrogen sulfide concentration equal to the TLV. The local ventilation rate is 4,000 ft3/min and is deemed average. The ambient pressure is 1 atm

Array Challenge Have the function ArrayChallenge (strArr) take the array of strings stored in strArr, which will only contain two strings of equal length and return the number of characters at each position that are different between them. For example: if strarr is ["house", "hours") then your program should return 2. The string will always be of equal length and will only contain lowercase characters from the alphabet and numbers, Examples Input: (*10011", "10100") Output: 3 Input: ["abcdef", "defabc)

Time Required: 10 minutesObjective: Examine a local scan in Wireshark. Description: This project lets you examine a trace file of an ARP-based reconnaissance probe. As you scroll through the ARP broadcasts, you should notice that this scan has some redundancy built infor example, it repeats a broadcast for 10. 0. 0. 55 and a few other IP addresses. To examine a local scan:1. Start the Wireshark for Windows program. 2. Click File, click Open, select the trace file arpscan. Pkt included with your data files, and then click the Open button. The packet summary window appears. This file contains a reconnaissance probe using ARP broadcasts to find active hosts. 3. Select Packet #1 in the trace file (if not already highlighted). The packet decode window displays the content of this frame. You see the Ethernet header addressed to broadcast (0xFF-FF-FF-FF-FF-FF). 4. Expand the Ethernet II and Address Resolution Protocol subtrees in the middle capture window to scroll through the packet and answer the following questions:a. What is the IP address of the device sending out the ARP broadcasts?b. What hosts were discovered?c. How could this type of scan be used on a small routed network?5. Close the arpscan. Pkt trace file and proceed immediately to 2
