1- A 480-V, 60-Hz, delta connected, synchronous generator has a synchronous reactance of 0.5 ohm and Its rated Line current is 100 A. if the generator is connected to a 480V grid

Draw the phasor diagram and find EA, delta angle and output power under the following conditions

a- The generator supply the rated current at 0.8 PF lagging.

b-The generator supply the rated current at 1.0 PF.

c- The generator supply the rated current at 0.8 PF leading.

Using values from Appendix C of your textbook, calculate the value of Ho, So, and Go for each of the following reactions at standard temperature (298 K). Next calculate G if ALL of the GASSES in the reaction have partial pressures of 0.2 atm.

(a) NaOH(s) + CO2(g) NaHCO3(s) Ho = -127.44 kJ/mol

So = -176.02 J/mol-K

Go = -74.96 kJ/mol

If all gasses have partial pressures of 0.2 atm then G = ________ kJ/mol.

(b) 2 Fe(s) + 3 CO2(g) Fe2O3(s) + 3 CO(g)

Ho = ______kJ/mol

So = _______ J/mol-K

Go = ___________kJ/mol

If all gasses have partial pressures of 0.2 atm then G = ___________kJ/mol.

(c) 2 C2H6(g) + O2(g) 2 C2H4(g) + 2 H2O(g)

Ho = ___________ kJ/mol

So = ________ J/mol-K

Go = ___________ kJ/mol

If all gasses have partial pressures of 0.2 atm then G = _________ kJ/mol.

(d) 6 C(graphite) + 6 H2O(l) C6H12O6(s)

Ho = _______ kJ/mol

So =________ J/mol-K

Go =_________ kJ/mol

If all gasses have partial pressures of 0.2 atm then G = __________ kJ/mol.

Given numRows and numCols, print a list of all seats in a theater. Rows are numbered, columns lettered, as in 1A or 3E. Print a space after each seat, including after the last. Ex: numRows = 2 and numCols = 3 prints:

1A 1B 1C 2A 2B 2C 

#include <iostream>
using namespace std;

int main() {
   int numRows = 2;
   int numCols = 3;

   // Note: You'll need to define more variables

   /* Your solution goes here */

   cout << endl;

   return 0;
}

Covid-19 started a derived demand, for instance, the high demand for hand sanitizer led to the derived demand of the isopropyl alcohol market .

What are some other covid- 19 derived demand, beside facemask ?

Definition of "Derived Demand"

Derived demand is a term in economics that describes the demand for a certain good or service resulting from a demand for related, necessary goods or services. For example, the demand for large-screen televisions creates a derived demand for home theater products such as audio speakers, amplifiers, and installation services.

A person with a cough is a persona non grata on airplanes, elevators, or at the theater. In theaters especially, the irritation level rises with each muffled explosion. According to Dr. Brian Carlin, a Pittsburgh pulmonologist, in any large audience you'll hear about 18 coughs per minute.

(b) Find the probability of four or fewer coughs (in a large auditorium) in a 1-minute period. (Use 4 decimal places.)

(c) Find the probability of at least eight coughs (in a large auditorium) in a 32-second period. (Use 4 decimal places.)

1. Sometimes consumers don’t face the same prices. For example, a movie theater may offer cheaper tickets to senior citizens, or local restaurants may provide student discounts. How would different prices charged to different people change our model of the consumer problem? Would people end up at points on the ICs with the same slope upon solving their consumer problems? If not, why wouldn’t they be able to improve themselves through mutually beneficial trades (keeping in mind the movie ticket and meal examples provided above)?

Consider a home theater system consisting of a television set, a receiver, a DVD player, and speakers. Draw a system diagram for this system. Include both components and links.What are the inputs to this system? What are the outputs? (Remember that the DVD player and receiver are both components within the system). Now draw a system diagram for the receiver subsystem. Include both its primary components and the links between them. What are the inputs and outputs for the receiver subsystem?

Do these inputs and outputs confirm to the links connected to the receiver in your system diagram?
