Hello,
Can someone solve this short exercise please. Only the calculation parts (a and c)
a) From the the given data:
The 2020 GDP / capita for Ni is 1.94
The 2020 GDP / capita for United States is 63.23
The equivalent CO2 emissions per equivalent US$ of GDP for Ni/geria
is 1.265
The equivalent CO2 emissions per equivalent US$ of GDP for United States is 0.218
c) From the typical trend predictions, the equivalent CO2 emission per equivalent US$ for the year 2035 is 513.59 T g C / yr
How to find the GDP per capitaGDP per capita is solved by gross domestic product GDP divided by population
GDP per capita for Ni/geria
= 400 / 206
= 1.94
GDP per capita for United States
= 20930 / 331
= 63.23
How to find equivalent CO2 emissions per equivalent US$ of GDPEquivalent CO2 emissions per equivalent US$ of GDP is gotten by
= CO2 emissions / GDP
Ni/geria
= 506 / 400
= 1.265
United States
= 4570 / 20930
= 0.218
How to compute equivalent CO2 emission per equivalent US$ for the year 2035 for Ni/geriaGiven that CO2 increment per year is 0.1% / yr. From 2020 to 2035 is 15 years and this shows increment of 15 * 0.1 = 1.5%
At 2020 it was 506 Tg C / yr with 1.5% increment we have
= 506 * 1.5%
= 7.59
The increment is 506 + 7.59 = 513.59 Tg C / yr
Therefore the equivalent CO2 emission per equivalent US$ for the year 2035 is 513.59 Tg C / yr

Air in a large tank at 300C and 400kPa, flows through a converging diverging nozzle with throat diameter 2cm. It exits smoothly at a Mach number 2.8. According to one-dimensional isentropic theory, what is
(a) exit diameter and
(b) mass flow?
Answer:
The answer is "[tex]3.74 \ cm\ \ and \ \ 0.186 \frac{kg}{s}[/tex]"
Explanation:
Given data:
Initial temperature of tank [tex]T_1 = 300^{\circ}\ C= 573 K[/tex]
Initial pressure of tank [tex]P_1= 400 \ kPa[/tex]
Diameter of throat [tex]d* = 2 \ cm[/tex]
Mach number at exit [tex]M = 2.8[/tex]
In point a:
calculating the throat area:
[tex]A*=\frac{\pi}{4} \times d^2[/tex]
[tex]=\frac{\pi}{4} \times 2^2\\\\=\frac{\pi}{4} \times 4\\\\=3.14 \ cm^2[/tex]
Since, the Mach number at throat is approximately half the Mach number at exit.
Calculate the Mach number at throat.
[tex]M*=\frac{M}{2}\\\\=\frac{2.8}{2}\\\\=1.4[/tex]
Calculate the exit area using isentropic flow equation.
[tex]\frac{A}{A*}= (\frac{\gamma -1}{2})^{\frac{\gamma +1}{2(\gamma -1)}} (\frac{1+\frac{\gamma -1}{2} M*^2}{M*})^{\frac{\gamma +1}{2(\gamma -1)}}[/tex]
Here: [tex]\gamma[/tex] is the specific heat ratio. Substitute the values in above equation.
[tex]\frac{A}{3.14}= (\frac{1.4-1}{2})^{-\frac{1.4+1}{2(1.4 -1)}} (\frac{1+\frac{1.4-1}{2} (1.4)^2}{1.4})^{\frac{1.4+1}{2(1.4-1)}} \\\\A=\frac{\pi}{4}d^2 \\\\10.99=\frac{\pi}{4}d^2 \\\\d = 3.74 \ cm[/tex]
exit diameter is 3.74 cm
In point b:
Calculate the temperature at throat.
[tex]\frac{T*}{T}=(1+\frac{\Gamma-1}{2} M*^2)^{-1}\\\\\frac{T*}{573}=(1+\frac{1.4-1}{2} (1.4)^2)^{-1}\\\\T*=411.41 \ K[/tex]
Calculate the velocity at exit.
[tex]V*=M*\sqrt{ \gamma R T*}[/tex]
Here: R is the gas constant.
[tex]V*=1.4 \times \sqrt{1.4 \times 287 \times 411.41}\\\\=569.21 \ \frac{m}{s}[/tex]
Calculate the density of air at inlet
[tex]\rho_1 =\frac{P_1}{RT_1}\\\\=\frac{400}{ 0.287 \times 573}\\\\=2.43\ \frac{kg}{m^3}[/tex]
Calculate the density of air at throat using isentropic flow equation.
[tex]\frac{\rho}{\rho_1}=(1+\frac{\Gamma -1}{2} M*^2)^{-\frac{1}{\Gamma -1}} \\\\\frac{\rho *}{2.43}=(1+\frac{1.4-1}{2} (1.4)*^2)^{-\frac{1}{1.4-1}} \\\\\rho*= 1.045 \ \frac{kg}{m^3}[/tex]
Calculate the mass flow rate.
[tex]m= \rho* \times A* \times V*\\\\= 1.045 \times 3.14 times 10^{-4} \times 569.21\\\\= 0.186 \frac{kg}{s}[/tex]
Do some research and find out whether the Pascaline calculator is a computer according to the Turing model.
No, it isn't. It can only perform basic mathematical calculations. A computer must be programmable in order to be Turing-complete.
What is Pascaline calculator?In 1642, Blaise Pascal invented the Pascal's calculator, a mechanical calculator. The laborious arithmetic calculations required by his father's work as the supervisor of taxes in Rouen inspired Pascal to create a calculator.
It must have some kind of programming language in which you can write instructions that can be followed automatically or by a human operator to perform any type of data processing.
Thus, it can be concluded that Pascaline calculator is not actually a computer according to the Turing model.

You are working on a residential heat pump. The heat pump is connected to a
240-V, 60-Hz power line. The compressor has a current draw of 34 amperes when operating. The compressor has a power factor of 70%. The backup strip heat is
rated at 10 kW. You need to know the amount of total current draw that will occur if
the strip heat comes on while the compressor is operating.
The amount of total current draw that will occur if the strip heat comes on while the compressor is operating is 53.778 A.
How to find the total currentWe have the following details
Pe = 10 Kw
compressor current = 34A
Power factor = 70%
The voltage applied = 240 V
frequency f = 60 Hz
P = ER² / R
= 240² / 10 x 10
= 57600 / 10000
= 5.76Ω
We have El = Lr = Et
El = Lr = 240
The true power P
10 x 10³ / 240
= 41.667 A
The total current is solved by
√41.667² + 34³
= √1736.138 + 1156
= √2892.138
= 53.778 A
Hence the amount of total current draw that will occur if the strip heat comes on while the compressor is operating is 53.778 A.

A spring applied and air-released service brake
The one that describes braking from a brake chamber containing a power spring is a spring applied and air-released service brake. The correct option is D.
What is spring brake?Spring brakes, unlike service brakes, are not air applied. They apply when air pressure is released from the brake chamber and release when air pressure is restored. Spring brakes and service brakes use different types of brake chambers.
The braking power of spring brakes is determined by how well the brakes are adjusted. If the brakes are not properly adjusted, neither the regular nor the emergency/parking brakes will function properly.
A spring applied and air-released service brake is the one that describes braking from a brake chamber containing a power spring.

iron(Fe) has a bcc crystal structure, an atomic radius of 0.124nm, and an atomic weight of 55.85g/mol. what is the theoretical density
Iron has a BCC crystal structure, an atomic radius of 0.124 nm and atomic weight of 55.85g/mol, so the theoretical density will be 7.8 g/cm³.
What is Atomic Radius?In a molecule, an atomic radius is equal to half the distance between neighboring atoms of the same element.
When we travel down a group, the atomic radius increases, and when we move in a period from left to right, it decreases. The valence electrons being in the same outermost shell at various times explains this. Moving from left to right, the atomic number rises during the same time interval, increasing the effective nuclear charge. Elemental atomic radius decreases as attractive forces rise.
The given values in the question are :
Radius=0.124 nm and,
Atomic weight=55.85 g/mol
For BCC, Z=2
r=0.124 nm=0.124×[tex]10^{-9}[/tex] m

(5 points) Knowing that the ammeter must be connected in series with the circuit and the voltmeter must be connected in parallel, what does this tells you about the internal resistance of each device?
This tells us that the internal resistance of the ammeter is very low because we would not want to impede the flow of current when trying to measure current. The internal resistance of the voltmeter must be high because it is added in parallel with the circuit and if added in series, it would cause resistance and alter the voltage reading.
