Answer:
the total work W = 29.05 kJ
the change in total internal energy is 
the total heat transferred in [kJ] is Q = 1.860 kJ
Explanation:
Given that
mass of carbon dioxide in the closed system = 1 kg
Temperature
= (273+30 ) K = 303 K
Pressure 
Pressure 
polytropic expansion n = 1.27
Note that we are also given the following data set:
R = 188.9 J/kg.K
c_v = 655 J/kg.K
So; for a polytropic process ; 

![T_2 = T_1 [\dfrac{P_2}{P_1}]^{\frac{n-1}{n}](https://tex.z-dn.net/?f=T_2%20%3D%20T_1%20%5B%5Cdfrac%7BP_2%7D%7BP_1%7D%5D%5E%7B%5Cfrac%7Bn-1%7D%7Bn%7D)
![T_2 = 303 [\dfrac{100}{200}]^{\frac{1.27-1}{1.27}](https://tex.z-dn.net/?f=T_2%20%3D%20303%20%5B%5Cdfrac%7B100%7D%7B200%7D%5D%5E%7B%5Cfrac%7B1.27-1%7D%7B1.27%7D)

Since the system does not follow the first order of thermodynamics; To calculate the total work by using the expression:


W = 29048.62222 J
W = 29.05 kJ
Thus, the total work W = 29.05 kJ
The change in internal energy can be expressed by the formula:




Hence; the change in total internal energy is 
Finally; to determine the total heat transferred in [kJ]; we go by the expression for the first order of thermodynamics which say:
Total Heat Q = ΔU + W
Q = (-27.19 + 29.05)kJ
Q = 1.860 kJ
Hence; the total heat transferred in [kJ] is Q = 1.860 kJ
Answer:
$51,020.41
Explanation:
The net present value is the present value of after tax cash flows from an investment less the amount invested.
PV = FV × (1 + r) ^ (-n)
PV = 25,000 (1 + 5%) ^ (-1) + 30000 (1 + 5%) ^ (-2)
= 51020.41
Where PV = present value
FV = Future value = 25,000 In year 1 and 30,000 In year 2
I = interest rate = 5%
N = time = 1 ,2

I think the three most important components of culture are food, religion, and language. Being a South African, I can provide you with interesting examples of all three.
When it comes to food, braaing is one of the best-known aspects of our food culture. It involves lighting a charcoal fire, putting a grid over it, and cooking meat like boerewors (a spiral sausage) and sosaties (pieces of meat and vegetables put on a stick).
The answer is true, it is because if two variables are having the same relationship having to have a positive effect, then both will move in the same direction in which both will produce a constant relationship, so the answer is true as all else remains constant.
