Question 2.1: (i) Calculate the number of electrons which will together weigh one gram. (ii) Calculate the mass and charge of one mole of electrons. * ------------------------------------------------- Answer (i) Mass of one electron = 9.10939 × 10–31 kg Number of electrons that weigh 9.10939 × 10–31 kg = 1 Number of electrons that will weigh 1 g = (1 × 10–3 kg) = 0.1098 × 10–3 + 31 = 0.1098 × 1028 = 1.098 × 1027 (ii) Mass of one electron = 9.10939 × 10–31 kg Mass of one mole of

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

HOUSE WIRING Wiring is not a duck soup. Period. If you are among those freebies‚ who want to do wiring just because their neighbors are doing it‚ you are on a wrong trail. Wiring is a very serious subject and it’s better to get some information about basicelectrical wiring before you step into it. Any gaffe can burn down your beautiful house in a few minutes. It is a common fact that people get confused when they are cabling for the first time. Gathering some information about circuits‚ wires and

ANATOMY 2 LAB 1 – RECEPTORS Questions: 1. How is the distance between receptors related to sensitivity of a stimulus? * The greater the distance between receptors and stimulus the lesser sensitive are the stimulus. The smaller area‚ the more sensitive. 2. What does the two-point discrimination test measure? * It measures the smallest distance at which two points of contact can be felt or measures areas that are more sensitive and has more motor interactions. 3. What areas of

Unit 4 Assignment 1) U.S. real GDP is substantially higher today than it was 60 years ago. What does this tell us‚ and what does it not tell us‚ about the well-being of U.S. residents? What are the limitations of the GDP as a measure of economic well-being? Given the limitations‚ why is GDP usually regarded as the best single measure of a society’s economic well-being? The GDP is defined as the market value of all final goods and services provided within a country in a given period of time. The
