Assume that we are given an acyclic graph G =(V, E). Consider the following algorithm for performing a topological sort on G: Perform a DFS of G. When- ever a node is finished, push it onto a stack. At the end of the DFS, pop the elements off of the stack and print them in order. Are we guaranteed that this algorithm produces a topological sort? (a) Not in all cases. (b) Yes, because all acyclic graphs must be trees. (c) Yes, because a vertex is only ever on top of the stack if it is guaranteed that all vertices upon which it depends are somewhere else in the stack. (a) This algorithm never produces a topological sort of any DAG (directed acyclic graph) (e) None of the above

Electron spin resonance (ESR) dating can be used on certain types of materials, specifically those containing crystalline structures with unpaired electrons. This dating method is commonly applied to materials such as tooth enamel, mollusk shells, and quartz grains, among others. These materials contain trapped charges resulting from natural radiation exposure, which can be measured using ESR techniques.

ESR dating is particularly useful for dating geological and archaeological samples that range in age from a few thousand years to millions of years. It can provide valuable insights into the age and history of the materials, allowing scientists to understand past environments, human evolution, and geological processes.

It's important to note that ESR dating is not applicable to all types of materials and has its limitations. The suitability of a material for ESR dating depends on its composition, preservation, and the availability of suitable paramagnetic centers for analysis.

The non-linearity error as a percentage of the full-scale reading at 100 degree C  is - 0.89%.

Non-linearity error is defined as the biggest deviation from a straight line linking the output signal to the applied force, known as the "best straight," that the calibration curve makes. In order to eliminate second order nonlinearity, the sensor signal conditioning system feeds a portion of the output signal back to the sensor.

If EMF and Celsius temperature have a proportional relationship, then the recorded value of EMF at 100 °C will be understood to be a temperature of.

T/5.268 = 400/21.846

T = 5.268(400/21.846) ≈ 96.457 °C

As a percentage of the full scale, the mistake is

(96.457 -100)/400 × 100% ≈ -0.886%

Inspectors

Explanation:

Inspectors are workers that are involved in the construction industry. Most of them can be called a building inspector due to their job consists mostly of inspecting electrical, mechanical or plumbing systems. Half of the people who are inspecting work for the local government. They mostly ensure that everything is up to date and follows the local government standards. The inspector's work begins even before the construction starts. They analyze the structural integrity of the blueprints, ensure that everything is safe, and inspect the location of the actual building. During the construction process they inspect the foundation, plumbing, electrical wiring, framing, and the mechanical system. They may issue a occupancy permit once the building is finished. Inspectors are required to have a thorough knowledge of their job and how it works. They are also required to know all the local building codes and regulations in order to determine whether or not the building is safe for use. Generally a good background and having expertise in electrical or plumbing systems is very desirable. Working conditions are similar to most construction workers although it may be less physically demanding. Inspectors normally take ladders, navigate through messy areas filled with tools or work in confined spaces.

The moment of inertia of the pendulum about an axis perpendicular to the page and passing through G will be 1.5 kgm².

A pendulum is a weight suspended from a pivot so that it can swing freely. The motion of a pendulum is a type of simple harmonic motion, which means that the pendulum moves back and forth in a regular, periodic fashion. The moment of inertia of an object is a measure of the object's resistance to change in its rotational motion.

To determine the location of the center of mass of the pendulum, we need to find the mass of each part and the distance from the center of mass of each part to point G.

The mass of rod AB is 3 kg/m * 1 m = 3 kg

The mass of rod OC is also 3 kg/m * 1 m = 3 kg

The mass of the plate is 12 kg/m2 * 1  = 12 kg

The distance from the center of mass of rod AB to point G is 0.5 m (since the rod is 1 m long and point G is at the midpoint of the rod)

The distance from the center of mass of rod OC to point G is also 0.5 m

The distance from the center of mass of the plate to point G is 0.5 m (since the plate is 1 m wide and point G is at the midpoint of the plate)

Now we can use the formula for the location of the center of mass:

yG = (3 kg * 0.5 m + 3 kg * 0.5 m + 12 kg * 0.5 m) / (3 kg + 3 kg + 12 kg) = 0.5 m

To calculate the moment of inertia of the pendulum about an axis perpendicular to the page and passing through G, we can use the formula for the moment of inertia of a rod about its center of mass:

\(I = (1/12) * m * L^2\)

For rod AB:

\(I = (1/12) * 3 kg * (1 m)^2 = 0.25 kg*m^2\\\)

For rod OC:

\(I = (1/12) * 3 kg * (1 m)^2 = 0.25 kg*m^2\)

For the plate:

I = (1/12) * 12 kg * (1 m)^2 = 1 kg*m²

The total moment of inertia of the pendulum is the sum of the moments of inertia of the individual parts:

I = 0.25 kgm^2 + 0.25 kgm^2 + 1 kgm^2 = 1.5 kgm²

i] The density of the pellet is 0.977 g/cm^{3}. ii] The macropore volume in cm^{3}/g is 0.205 cm^{3}/g. iii] The macropore void fraction in the pellet is 25.1%.iv] The micropore void fraction in the pellet is 49.0%. v] The solid fraction of the pellet is 25.9%. vi] The density of the particles is 1.222 g/cm^{3}.

i] To determine the density of the pellet, we can use the formula:

Density = Mass / Volume

Given that the mass of the pellet is 3.15 g and the volume is 3.22cm^{3}, we can calculate the density as follows:

Density = 3.15 g / 3.22 cm^{3}≈ 0.977 \(g/cm^{3\)

ii] The macropore volume in cm3/g can be calculated by dividing the macropore volume of the pellet (0.645 cm3) by the mass of the pellet (3.15 g):

Macropore volume = 0.645 cm^{3} / 3.15 g ≈ 0.205 \(cm^{3} /g\)

iii] The macropore void fraction in the pellet can be calculated using the formula:

Macropore void fraction = Macropore volume / Total volume of the pellet

Total volume of the pellet = Volume - Macropore volume = 3.22 cm^{3}- 0.645 cm^{3} = 2.575 cm^{3}

Macropore void fraction = 0.645 cm^{3} / 2.575 \(cm^{3}\)≈ 0.251 or 25.1%

iv] The micropore void fraction in the pellet can be calculated using the given micropore volume of the particles (0.40 cm^{3} /g) and the mass of the pellet (3.15 g):

Micropore volume in the pellet = Micropore volume/g x Mass

Micropore volume in the pellet = 0.40 \(cm^{3} /g\) x 3.15 g = 1.26 cm3

Micropore void fraction = Micropore volume in the pellet / Total volume of the pellet

Micropore void fraction = 1.26 \(cm^{3}\) / 2.575 \(cm^{3}\) ≈ 0.490 or 49.0%

v] The solid fraction of the pellet can be calculated by subtracting the sum of macropore and micropore void fractions from 1:

Solid fraction = 1 - (Macropore void fraction + Micropore void fraction)

Solid fraction = 1 - (0.251 + 0.490) ≈ 0.259 or 25.9%

vi] The density of the particles can be determined using the mass of the pellet (3.15 g) and the total volume of the particles:

Total volume of the particles = Volume - Macropore volume = 3.22 \(cm^{3}\)- 0.645 \(cm^{3}\) = 2.575\(cm^{3}\)

Density of the particles = Mass / Total volume of the particles

Density of the particles = 3.15 g / 2.575\(cm^{3}\) ≈ 1.222 \(g/cm^{3}\)

Answer:

The net work done is 272.38 kJ

Explanation:

The parameters given are;

Mass of water = 5 kg

p₁ = 20 bar

T₁ = 360°C

v₁ = 0.141147 m³/kg  

Process 1 to 2 = Constant pressure process

p₂ = 20 bar

Process 2 to 3 = Constant volume process

p₃ = 5 bar

Process 3 to 4 = Constant pressure process

Process 4 to 1 = Polytropic process pv = Constant

For Stage 1 to 2, we have;

p₂ = 20 bar

From the steam tables for superheated steam, we have;

T₂ = 212.385°C

v₂ = 0.0995805 m³/kg

Work done = p₂×(v₂ - v₁) = 2×10⁶ × (0.0995805 - 0.141147 ) = -83133 J/kg

For the 5 kg, we have;

\(W_{1-2}\) = -83133 J/kg × 5 = -415,665 J

Stage 2 to 3: Constant volume cooling

v₂ = v₃ = 0.0995805 m³/kg

p₃ = 5 bar

T₃ = 151.836°C

(0.0995805 - 0.00109256)/(0.374804 - 0.00109256) = 0.2635 liquid vapor mixture

Work done, \(W_{2-3}\) = 0

Stage 3 to 4: Constant pressure heating

p₃ = p₄ = 5 bar

v₄/T₄ = v₃/T₃

v₄ =  0.374804 m³/kg

T₄ = v₄×T₃/v₃ = 0.374804*(273.15 + 151.836)/0.0995805 = 1599.6 K = 1326.4 °C

Work done = p₄×(v₄ - v₃) = 5×10⁵ × (0.374804  - 0.0995805 ) = 137611.75 J/kg

For the 5 kg, we have;

\(W_{3-4}\) = 137,611.75  J/kg × 5 = 688,058.75 J

Stage 4 to 1: Polytropic process    

\(\dfrac{p_{4}}{p_{1}} = \left (\dfrac{V_{1}}{V_{4}} \right )^{n} = \left (\dfrac{T_{4}}{T_{1}} \right )^{\dfrac{n}{n-1}}\)

Which gives;

\(\dfrac{5}{20} = \left (\dfrac{0.141147 }{0.374804} \right )^{n}\)

n = log(5/20) ÷log(0.141147/0.374804) = 1.42

Work done, \(W_{pdv}\), is given as follows;

\(W_{pdv} = \dfrac{p_4 \times v_4 -p_4 \times v_4 }{n-1}\)

Which gives;

\(W_{pdv} = \dfrac{5\times 0.374804 -20\times 0.141147 }{1.42-1} = -2.259 \, J\)

For the 5 kg, we have;

\(W_{4-1}\) = -2.259 J/kg × 5 = -11.2967 J

The net work done, \(W_{Net}\), is therefore;

\(W_{Net}\) = \(W_{1-2}\)  + \(W_{3-4}\) + \(W_{4-1}\)

-415,665  + 688,058.75 -11.2967 = 272,382.45 J = 272.38 kJ.
