The final compound which I am going to look at is 4-aminobenzenecarboxylic acid. The compound is also known as 4-Aminobenzoic acid. The molecular and structural formula of the compound is C7H7NO2 which means that the compound consists of seven carbon atoms attached to seven hydrogen atoms along with one nitrogen atom and two carbon atoms attached as a carbon-oxygen double bond. The displayed formula for the 4-aminobenzenecarboxylic acid compound is shown and it shows the formula in a ring form therefore

Alarms DeVry University NETW420 Alexander Davis Jun 1‚ 2014 This week’s assignment is to describe various event categories and event based transactions that are used by the Network Management System. It would be impossible to categorize all potential causes for alarms in all existing network systems however‚ understanding some common alerts and categories is essential for any network manager. Many Network Management Systems have a log and event manager that collects data

Assignment Week 4 Chapter 11 20. A parallel RL circuit has values of IL = 240 mA and IR = 180 mA. Calculate the magnitude and phase angle of the circuit current. It=√ IL^2 + IR^2= √ 240mA^2 + 180mA^2= 0.3 x 10^-3= 300mA θ= tan^-1(-IL/IR)= (-240mA/180mA)= -53° 300mA∟-53° 22. Calculate the total impedance for the circuit shown in Figure 11.38b. It= √IL^2 + IR^2= √800mA^2 + 120mA^2= 0.808949 x 10^-3= 808.95mA Zt= Vs/It= 120V/808.95mA = 148Ω θ= tan^-1(-IL/IR)= (-800mA/120mA)= -81.5= 82° 148∟82° 24

Lab 4 Projectile Motion Sai Moua Purpose: The purpose of this lab was to define what the initial velocity of the ball when it is launched out of the pipe. Our next objective is to determine at what angle that the ball will be ejected at the maximum range. Lastly‚ we predict and confirm the range before we launch the ball at a certain angle. Theory: Projectile motion according to Dr. James S. Walker is defined as‚ “the motion of objects that are initially launched –or “projected”- and that
