*Please answer all three parts

Three Part Question: X. (A) NASA Atmospheric Mission balloons use helium that expands to almost 1 million cubic meter at the top of the atmosphere where pressure is 0.003 atm only. Even though it takes about 2.5 hours to get to this altitude, it is assumed that the rise is fast enough to be considered as adiabatic. Find the initial volume of the helium at the ground level. (Helium is a mono-atomic gas). (B) If the initial temperature of the gas was 15 degree celsius what is the temperature of the gas at the top? Ignore real atmospheric temperature changes. (C) What is the change in internal energy of the gas?

The new car sales professional’s job at a major car dealer network does not motivate many of the individuals who hold this job because they feel that the scope of the job is too narrow. Specifically, current and past sales professionals have said that while they are able to show customers various options for vehicles, they cannot be involved in negotiating the final selling price of the vehicle, nor can they handle the business side of the transaction in terms of getting loan approvals, completing the final paperwork for the sale, etc. Based on the job characteristics model, what would you do to address these issues if you were the manager?

A. Increase skill variety
B. Decrease autonomy
C. Increase task identity
D. Increase feedback

The college IT department manager no longer wants to use spreadsheets to calculate grades. The manager has asked you to create a program that will input the teachers' files and output the students' grades.

Write a Ruby program named format file.rb, which can be run by typing ruby widgets.rb.

In your Ruby environment, the program must read an input file formatted in CSV format, named input.csv. Each record contains data about a student and their corresponding grades.

The data will look similar to the following:

Student Name, assignment 1, assignment 2, assignment 3, assignment 4

John Adams, 90, 91, 99, 98

Paul Newman, 90, 92, 93, 94

Mary Smith, 95, 96, 99

Be careful to follow the output format exactly, including spacing. The output of your program must look like the following:

Student Assignment Average

John Adams    94.5

THIS IS IN PYTHON 3.0

Let's call the first function power(a,b). Use the built-in power function a**b in python to write a second function called testing(c) that tests if the first function is working or not.

I already have the function power(a,b), which is as follows:

def power(a, b):

    if (b == 0): return 1

    elif (int(b % 2) == 0):

        return (power(a, int(b / 2)) *

               power(a, int(b / 2)))

    else:

        return (a * power(a, int(a / 2)) *

                   power(a, int(b / 2)))

1.) What is the absolute pressure of the air in your car's tires, in psi, when your pressure gauge indicates they are inflated to 35.0psi ? Assume you are at sea level.

Succinyl-CoA inhibits both citrate synthase and α-ketoglutarate dehydrogenase. How is succinyl-CoA able to inhibit both enzymes?

C programming

Program must use FileIO to read in a file formatted like below and print it to the screen;

#include<stdio.h>

#include<stdio.h>

int main)int argc, char * argv[])
{
    printf("hello\n");
    return 0;
}

it then must check if there are balanced Parentheses and balanced brackets.  

If it is balanced it must display "Code is balanced" and if its not balanced it must display "code is not balanced"

Just have a quick question about IT in general. If there are any good study techniques/websites/youtube videos that can help explain how to use Python on a Macbook, I could really use the help. I'm currently running OSX 10.10.5 on my Mac, and am using the Python Crash Course book by Eric Matthes to reference.

What are the three parameters associated with an increase of dose on the worker? How could this dose possibly be minimized?

Hillsong Inc. manufactures snowsuits. Hillsong is considering purchasing a new sewing machine at a cost of $2.45 million. Its existing machine was purchased five years ago at a price of $1.8 million; six months ago, Hillsong spent $55,000 to keep it operational. The existing sewing machine can be sold today for $245,090. The new sewing machine would require a one-time, $85,000 training cost. Operating costs would decrease by the following amounts for years 1 to 7: Year 1 $389,800 2 399,800 3 410,200 4 425,400 5 432,400 6 435,000 7 436,000 The new sewing machine would be depreciated according to the declining-balance method at a rate of 20%. The salvage value is expected to be $380,800. This new equipment would require maintenance costs of $99,000 at the end of the fifth year. The cost of capital is 9%. Click here to view PV table. Use the net present value method to determine the following: (If net present value is negative then enter with negative sign preceding the number e.g. -45 or parentheses e.g. (45). Round present value answer to 0 decimal places, e.g. 125. For calculation purposes, use 5 decimal places as displayed in the factor table provided.) Calculate the net present value. Net present value $ Determine whether Hillsong should purchase the new machine to replace the existing machine?

Debate has emerged and raged on regarding many African countries including Ghana not making rapid economic progress in an emerging knowledge economy. Poverty exists in spite of development being driven by technology, fuelled by information and powered by knowledge, and, many are oblivious to the reality that information and communication technology (ICT) cuts across all aspects of our lives.
We take a queue from the ICT driven economic experiences of the United States during the dot com boom and developments in Finland and other Western economies. We are informed by issues of globalization, the knowledge economy and the transformation of business processes using ICT in India, China, Korea and Malaysia. Close to us in Africa we are encouraged by economic growth using ICT in Rwanda and South Africa.
Pundits have argued that illiteracy is to be blamed, and mathematics and science education needs to be prioritized. Others say it is in our attitude fashioned by our past which does not relate development as an independent variable relative to other variables such as technology. While some view our challenges as lack of leadership to implement sustainable ICT policies and strategies at a macro and micro level, many argue that development of a nation’s economy has much to do with input from ICT personnel. They do not only belong to the domain of personnel with tacit knowledge of engineers who should provide infrastructure but such need to study policies that determine development
