Carbon dioxide, which is recognized as the major contributor to global warming as a "greenhouse gas," is formed when fossil fuels are combusted, as in electrical power plants fueled by coal, oil, or natural gas. One potential way to reduce the amount of CO2 added to the atmosphere is to store it as a compressed gas in underground formations. Consider a 1000-megawatt coal-fired power plant that produces about 5×106 tons of CO2 per year.

Part A

Assuming ideal gas behavior, 1.00 atm, and 37 ∘C, calculate the volume of CO2 produced by this power plant.
Express your answer using one significant figure.

Part C

If it is stored underground as a gas at 34 ∘C and 70 atm , what volume does it occupy?
Express your answer using one significant figure.

V =     L

For the circuit shown in the figure, calculate the following. (Assume  = 7.32 V and R = 5.70 Ω.)

A rectangular circuit begins at point a on its left side. On its top side, the circuit splits into two parallel horizontal branches.

• The top branch contains, from left to right, a 12.0 V battery and a 4.00 Ω resistor. The positive terminal of the battery is to the left of its negative terminal.
• The bottom branch contains a 2.00 Ω resistor.

The top and bottom branches recombine to meet at point b, which is to the right of the branches. The right side of the rectangular circuit extends down from the bottom branch, just to the right of the 2.00 Ω resistor and to the left of point b. The bottom side of the rectangle, from right to left, contains a resistor R and a battery labeled emf ℰ, where its positive terminal is to the right of its negative terminal. The circuit extends to the left from the negative terminal until it reaches point a, completing the circuit.

A. In the context of the Standard Trade Model, describe the economic elements that dictate differences between the production possibilities frontiers of different countries. B. Suppose the U.S. produces clothing and food. The price of one pound of food is $2 while the price of one yard of cloth is $5. Write down the equation for the isovalue line given that the total production is V. C. Suppose that V=$100 and that the US produces 10 lbs of food. Draw the PPF, the isovalue line and indicate the production point given these parameters (Use Cloth on the vertical axis and Food on the horizontal axis). What is the slope of the isovalue line given the prices in part B? D. The U.S. has preferences such that they like to consume more cloth and less food. Suppose that the demand for food is 5 lbs of food. What would be the demand for cloth given a production value V=$100 and the price of one pound of food being $2 and price for cloth being $5. Describe what the U.S. will trade by calculating imports and exports. Illustrate in a graph by showing where the U.S. will consume and where they produce.

Describe elastic, inelastic, and completely inelastic collisions. Which type of collisions are you going to investigate in the lab?

Do you expect the linear momentum of the system to be conserved in your experiment?In which part? Explain why.

Do you expect kinetic energy of the system to be conserved in your experiment? In which part? Explain why.

In one trial for inelastic collisions in the experiment, cart 1 has mass m1 and is initially moving with velocity v ⃗_1i to the right. Cart 2 with mass m2 is initially moving with velocity v ⃗_2i also to the right. The velocity of the cart 1 is larger than the velocity of cart 2 causing a collision between both carts. After the collision, the carts stick together and move with velocity v ⃗_f to the right.

Write down the expression for the magnitude of linear momentum of the system before collision.

Write down the expression for the magnitude of linear momentum of the system after the collision.

Write down the expression for the magnitude of kinetic energy of the system before collision.

Write down the expression for the magnitude of the kinetic energy of the system after the collision.

For Si single crystals: ni = 1.45 x 1010 cm-3 ; electron mobility µn = 1400 cm2 V-1 s-1 ; hole mobility µp = 450 cm2 V-1 s-1 . (a) A single crystal of Si is highly doped with B (a p-type dopant). It has a measured resistivity of 1.5 x 10-3 W-cm.

a) What are the free hole (p) and free electron (n) concentrations (in carriers/cm3 ) in the material?

b) If a quantum dot (diameter = 5 nm) is made from the above silicon wafer, how many dopant atoms are in a single quantum dot? Assume that the quantum dot is spherical, so the volume of the dot, V = 4/3 pr 3 , where r = dot radius = 1/2 dot diameter.

c) If a quantum dot (diameter = 5 nm) is made from the above silicon wafer, how many silicon atoms are in a single quantum dot? Assume that the quantum dot is spherical, and the density of silicon is 2.33 g/cm3 .

Similar conditions as in previous question. A simple 3-phase power system includes generator G, step-up transformer TX1, transmission line TL, step-down transformer TX2 and load L. All elements are rated for S = 50 MVA (3 phase).

G: series impedance 0, rated voltage 600 V (line-to-line)

TX1: series impedance Z_TX1, voltage ratio 600 V : 100 kV (line-to-line)

TL: series impedance Z_TL;

TX2: series impedance Z_TX2; voltage ratio 100 kV : 1kV (line-to-line)

L: impedance Z_L.

Per unit system is based on  S = 50 MVA and the first base voltage V_baseG = 600 V (line-to-line) at the generator. In per unit system representation, current through the entire system equals 0.32 + j0.58 per unit.

Determine current (magnitude only) in the transmission line (TL) in Amps. Express your answer as a number with one digit after decimal point (as in 123.4)

language c++ finish the code and hurry in an exam with less then 30 minutes

#include <iostream>

#include <vector>

using namespace std;

int find(vector<int> & v, int value);

int main(){

vector<int> myVec = {2,30,10,50,100,32,19,43, 201, 311, 99,77,45,15,95, 105, 32, 15};

//complete code here

cout << "First Element is: " << endl;

cout << "Last Element is: " << endl;

cout << "The number of elements is: " << endl;

//Complete the missing code

cout << "Find 201 : result is at index " << endl;

cout << "Find 299 : result is at index " << endl;

return 0;

}

int find(vector<int> & v, int value){

//complete the code here

return -1;

}

return 0;

}

output should be like this

first element is : 2

Last element is :15

the number of element is :18

write a function find that takes in the vector and the value you would like to find

int find(vector<int)> & v, int value)

find 201: result is at index 8

find 299: result is at index -1

I. Answer part A,B, C and D.

1a)

Count the number of times a given char occurs in a given range of a String parameter (i.e. starting at a given start index, and up to but not including and end index). If end is greater than the length of the String, then the method should stop looking at the end of the String.

countCharsInRange("java", "v", 1, 2) → 0
countCharsInRange("java", "v", 0, 2) → 0
countCharsInRange("java", "v", 0, 3) → 1

1b)

Return a new String that removes all copies of the given char ch from the given String

removeChar("dog", "o") → "dg"
removeChar("cat", "o") → "cat"
removeChar("aaa", "a") → ""

1c)

Return the number of times the letter 'a' is directly followed by the letter 'b' in the given String.

countAB("abc") → 1
countAB("wxyz") → 0
countAB("bcaca") → 0

1d)

Return a new String that is a copy of the given String with each character copied the given number of times. Assume that n is 0 or more.

eachCharNTimes("abc", 2) → "aabbcc"
eachCharNTimes("xyz", 3) → "xxxyyyzzz"
eachCharNTimes("a", 5) → "aaaaa"
