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

The Effect of Increasing Temperatures on the Enzyme Catalase Enzymes are proteins that help speed up chemical reactions inside your body and without enzymes‚ chemicals reactions in cells would be incredibly slow to a point where no activity at all takes place (Brawo press Inc‚ 2017). Enzymes speed up the chemical reactions by lowering the activations energy and they do this by binding substrates together in the correct orientation to react (Ernest Z‚ 2014). They are vital for life and serve a

Enzymes are generally protein macromolecules that act as catalysts in metabolic reactions. A catalyst is a chemical agent that speeds up a reaction without being consumed by the reaction. Enzymes speed up metabolic reaction rates by lowering the activation energy barrier‚ which is the amount of energy initially needed to spark a reaction. It allows reactant molecules to absorb enough energy to break bonds and react without raising the temperature to an extreme. During this process the substrate

The Determination of the Effect of pH on Amylase Activity Grace Chung Abstract: Amylase is an important enzyme in the human body as it allows for the consumption of starch by breaking the polysaccharide down into maltose units. All enzymes‚ including amylase‚ function best at a certain optimal pH. Therefore‚ in this experiment‚ the effect of different pHs on the reaction rate of amylase is studied. It was hypothesized that the amylase-starch reaction would proceed fastest at a pH closest to

2.3 Results 2.3.1 The Effect of O. lybicus Population on Palms Temperature Over Time Temperature differences between different O. lybicus population levels were not significant in leaves and fronds (P > 0.05). However‚ high significance difference in temperature were occurred over time (P < 0.001) in both parts Figure 1 and 2. The temperature at the highest population (1000 insects) were the highest at the first three weeks‚ before it starts declining gradually (figures 14-15). Chlorophyll measurements

Our task at hand is to start wiring the building for a new computer science and electrical engineering labs. This building will have a lot of devices that need to be connected to the school campus network and we will need a lot of tools to do it. First off I think since our building is going
