Dropping an electrical appliance into water, making it a foreign conductor, causes a: D. short circuit.

Conduction can be defined as a process which involves the transfer of electrical charge from one point to another in an electrical circuit, especially due to the movement of particles (electrons).

This ultimately implies that, when the conduction relates to electrical charge, it is referred to as electrical conduction.

In Electrical engineering, a short usually causes an electrical circuit protection device such as a fuse, circuit breaker, etc., to open when higher than normal current flows through the electrical circuit.

In this context, we can reasonably infer and logically deduce that a short circuit would occur when an electrical appliance is dropped into water.

The maximum axial compressive stress that a cohesive soil specimen can withstand with no confining stress is known as unconfined compressive strength (UCS).

One of the quickest and least expensive ways to gauge the shear strength of clayey soil is the unconfined compression test. The unconfined compression test is the most popular method of soil shear testing because it is one of the fastest and least expensive methods of measuring shear strength. It is used primarily for saturated, cohesive soils recovered from thin-walled sampling tubes. The primary purpose of the Unconfined Compression Test is to quickly determine a measure of the unconfined compressive strength of rocks or fine-grained soils that possess sufficient cohesion to permit testing in the unconfined state.

Answer:

Part A

The flow of the bee lava is inertia dominant and laminar

Part B

The flow of a baseball in Mars is inertia dominated and the flow is laminar

Part C

The flow of an elderly on i95 is viscous force dominated and turbulent

Explanation:

The Reynold's number when inertia is dominant is low, and the flow is laminar

When viscous force is dominant, the Reynold's number is high, and we have turbulent flow

The Reynold's number of laminar flow is Re < 2,000

The Reynold's of unstable or intermediate flow is 2,000 < Re < 4,000

The Reynold's number of turbulent flow is Re > 4,000

Therefore, we have;

Part A

The Reynold's number of a bee lava, Re = 0.2, therefore, the flow is inertia and laminar

Part B

The Reynold's number of the ball in Mars is Re = 500, therefore, given that the Reynold's number is less than 2,000, the inertia is dominant, and the flow is laminar flow

Part C

The Reynold's number of the driver on i95 = 1,200,000 which is larger than 4,000, therefore, the flow is viscous force dominated and the flow is turbulent.

2.1) The support reactions are calculated now: \(A_{x} = 10\,kN\), \(A_{y} = -10\,kN\), \(B_{y} = 30\,kN\).

2.2) The member CD is on tensile load and the member BC is on compressive load. \(F_{BC} \approx 28.284\,kN\), \(F_{CD} = 20\,kN\)

The dynamic situation of a mechanical system whose geometry cannot be neglected is described by Newton's laws and D'Alembert's principle. A planar system in equilibrium is described by the following formulae:

\(\sum F_{x} = 0\)     (1)

\(\sum F_{y} = 0\)     (2)

\(\sum M = 0\)     (3)

2.1) The support reactions can be found by assuming that the truss is a rigid solid:

\(\sum F_{x} = A_{x} - F = 0\)    (4)

\(A_{x} = F\)

\(A_{x} = 10\,kN\)

\(\sum M_{A} = F\cdot r_{BD} - G \cdot (r_{AB}+r_{CD}) + B_{y}\cdot r_{AB} = 0\)     (5)

\(B_{y} = \frac{G\cdot (r_{AB}+r_{CD})-F\cdot r_{BD}}{r_{AB}}\)

\(B_{y} =\frac{(20\,kN)\cdot (8\,m)-(10\,kN)\cdot (4\,m)}{4 \,m}\)

\(B_{y} = 30\,kN\)

\(\sum F_{y} = A_{y} + B_{y} - G = 0\)     (6)

\(A_{y} = G - B_{y}\)

\(A_{y} = 20\,kN - 30\,kN\)

\(A_{y} = -10\,kN\)

Note - The negative sign means that the real direction of the component is antiparallel to the assumed one.

2.2) If the entire system is at equilibrium, then every part of the system must be also at equilibrium. The joint is considered a particle and thus the D'Alembert's principle is not necessary. The member CD is on tensile load and the member BC is on compressive load.

\(\sum F_{x} = F_{BC} \cdot \cos 45^{\circ} - F_{CD} = 0\)     (7)

\(\sum F_{y} = -G + F_{BC}\cdot \sin 45^{\circ} = 0\)     (8)

By (8):

\(F_{BC} = \frac{G}{\sin 45^{\circ}}\)

\(F_{BC} \approx 28.284\,kN\)

Neo-luddites argue that the technologies such as computers, automobiles, internet etc. are necessary and they have made significant improvement in our life. [FALSE]

A Neo-Luddite is someone who believes that the use of technology has serious ethical, moral, and social ramifications. Operating under this belief, Neo-Luddites are critical of technology and cautious to promote its early adoption. While they are not necessarily opposed to technology, they would prefer to see a more serious discussion of the role of technology in society. Some Neo-Luddites actually dislike technology, opting for a life of "voluntary simplicity," but this is not always the case.

The term "Luddite" comes from a political movement during the Industrial Revolution. The Luddites disliked the spread of mechanical devices such as mechanized looms to accomplish tasks which were formerly performed by people. They held marches, destroyed factories, and engaged in other types of activism in an attempt to prevent further technological development. Ultimately, the Luddites were unsuccessful, but when people started to question technology in large numbers again in the 1970s, they revived the concept, calling themselves the "New Luddites," and the Neo-Luddite movement was born.

t necessarily refer to themselves as Neo-Luddites, although some do.

When a refrigeration system's suction line is noticeably cold instead of just being cool , it probably contains refrigerant. The correct answer for this is D. low -pressure vapor

If a refrigeration system's suction line is noticeably cold instead of just being cool, it is an indication that it probably contains refrigerant. The question is asking which type of refrigerant is most likely present in the suction line. In this scenario, we can rule out high-pressure liquid since the suction line is not designed to carry liquids. The same reasoning applies to high-pressure vapor as well since vapor will not condense in the suction line. This leaves us with two options: low-pressure liquid and low-pressure vapor. However, the suction line is connected to the evaporator, where refrigerant absorbs heat and turns into vapor. Therefore, it is likely that the suction line contains low-pressure vapor.

Answer:

A) L = 0.388 μm

B) D = 3.78 mm

Explanation:

We are given;

Characteristics impedance; Z_o = 75 ohms

Nominal capacitance; C = 69pF/m = 69 × 10^(-12) F/m

dielectric constant; k = 2.23

Inner diameter of conductor; d = 0.584 mm

A) Now formula for Characteristics impedance is given as;

Z_o = √(L/C)

Where L is the inductance per metre.

Making L the subject, we have;

L = (Z_o)²C

L = 75² × 69 × 10^(-12)

L = 0.388 × 10^(-6) m

L = 0.388 μm

B) To get the outer diameter, we will use the formula;

Z_o = (138/√k) log(D/d)

Where;

D is outer diameter.

Thus, Plugging in the relevant values;

75 = (138/√2.23) × log (D/0.584)

log (D/0.584) = 0.81158611538

(D/0.584) = 10^(0.81158611538)

D/0.584 = 6.48016576435

D = 6.48016576435 × 0.584

D = 3.78 mm

Consider that it is needed to assign each of Floyd’s customers to a distribution center that is at the closest distance to the customer. The customer zip codes have been given and their distances from each of the five distribution centers in the referred data file “Floyds”.

Since the interest is in determining the center which is at the shortest distance from the customer, the shortest distance is obtained for each customer. So in the cell G3, use the function written below:

= MIN(B4:F4)

The value obtained is 731. Drag this formula down for all 1029 customers. Now that the minimum distance for each customer has been obtained, it is needed to find out the distribution center for the corresponding distance. For this, first, find the position at which this minimum distance value occurs in the array of five distances. So in cell H4, enter the below formula:

= MATCH (G4, B4; F4, 0)

This function looks for the contents of cell G4 in the range B4 to F4 and returns the position in the array at which it occurs. Since the distance 731 in cell G4 occurs at 1st position in the array of cells from B4 to F4, the function returns value 1 in cell H4. Drag this formula for all 1029 customers.

Step 3/3

Now it is needed to associate each position with the distribution center. For this, use the Index function in cell I4 as below:

= INDEX ($B$2: $F$2, H4)

This function returns the value of the position stated in cell H4 from the range B2 to F2. Now cells B2 to F2 contain the names of all the five distribution centers.

So, by giving this above function, the distribution center is obtained for first customer as Charlotte, NC. Drag this formula for all 1029 customers so that each customer is assigned the nearest distribution center

Answer:

The answers are in the explanation. The pH is 5.91

Explanation:

The CH3NH2 reacts with HCl as follows:

CH3NH2 + HCl → CH3NH3⁺ + Cl⁻

When 200mL of HCl are added, the moles of CH3NH2 and HCl are reacting completely producing CH3NH3+ and Cl-. That means the species present are:

no H+. All reacted

yes H2O. Because the water is present in the solutions of HCl and CH3NH2

yes Cl-. Is a product of the reaction

Yes CH3NH2. Is consumed in the reaction but comes from the equilibrium of CH3NH3+

yes CH3NH3+. Is the other product of the reaction. MAJOR SPECIES

When 300.00mL of HCl are added, 100mL are in excess:

yes H+. Is in excess: H+ + Cl- = HCl in water. MAJOR SPECIES. Determine the pH of the solution.

yes H2O. Is present because the reactants are diluted.  

yes Cl-. Is a product of reaction and comes from HCl.

Yes CH3NH2. The reactant is over but comes from the equilibrium of CH3NH3+

yes no CH3NH3+. Yes. Is a product and remains despite HCl is in excess.

To find the pH:

At equivalence point the ion that determines pH is CH3NH3+. Its concentration is:

0.100L * (0.200mol/L) = 0.0200 moles / 0.300L = 0.0667M CH3NH3+

The equilibrium of CH3NH3+ is:

Ka = Kw/kb = 1x10-14/4.4x10-4 = 2.273x10-11 = [H+] [CH3NH2] / [CH3NH3+]

As both [H+] [CH3NH2] comes from the same equilibrium:

[H+] =  [CH3NH2] = X

2.273x10-11 = [X] [X] / [0.0667M]

1.5159x10-12 = X²

X = 1.23x10-6M = [H+]

As pH = -log [H+]

pH = 5.91

The pH at the equivalent point for this titration is "5.91".

\(CH_3NH_2 = 0.200\ M\\\\ \text{volume} = 100.0\ mL = 0.100\ L\\\\HCl = 0.100\ M\\\\\)

We must now quantify the pH well at the equivalence point.

We know that even at the point of equivalence, moles of acid and moles of the base are equivalent. As such, first, we must calculate the number of moles of the given base.

Calculating the Moles in \(CH_3NH_2 = 0.200\ M \times 0.100\ L = 0.0200\ moles\)

Calculating the Moles in \(HCl = 0.0200 \ moles\)

Calculating the volume of \(HCl\):

\(\to \text{Molarity} = \frac{ \text{moles}}{\text{volume \ (L)}} \\\\\to \text{Volume} = \frac{\text{moles}}{\text{molarity}}\\\\\)

                \(= \frac{0.0200 \ moles}{ 0.100\ M}\\\\= 0.200 \ L\\\\= 200 \ mL\\\\\)

Calculating the reaction among the acid and base:

\(CH_3NH_2 + HCl \longrightarrow CH_3NH_3^{+} + Cl^-\)

\(0.0200 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.0200 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.0200\)

Therefore the conjugate acid of the bases exists at the standard solution.

Then we must calculate the new molar mass of \(CH_3NH_3^+\).

Total volume\(= 100 + 200 = 300\ mL = 0.300\ L\)

\([CH_3NH_3^+] = \frac{0.0200\ mole}{ 0.300\ L}= 0.0667\ M\)

Using the ICE table

\(CH_3NH_3^+ + H_2O \longrightarrow CH_3NH_2 + H_3O^+\)

\(I \ \ \ \ \ \ \ \ \ \ 0.0667 \ \ \ \ \ \ \ \ \ 0\ \ \ \ \ \ \ \ \ 0\\\\C\ \ \ \ \ \ \ \ -x\ \ \ \ \ \ \ \ +x \ \ \ \ \ \ \ \ +x\\\\E \ \ \ \ \ \ \ \ \ \ \ \ 0.0667-x \ \ \ \ \ \ \ \ \ \ \ \ +x \ \ \ \ \ \ \ \ \ \ \ \+x\\\\\to Ka = \frac{[CH_3NH_2] [H_3O^+] }{[CH_3NH_3^+]}\)

Calculating \(K_a\) from \(K_b\)

\(\to K_a \times K_b = 1\times 10^{-14}\\\\\to K_a = \frac{1\times 10^{-14}}{4.4\times 10^{-4}} = 2.27\times 10^{-11}\\\\\)

                           \(= 2.27\times 10^{-11} \\\\= x\times \frac{x}{(0.0667-x)}\)

The x in the 0.0667-x can be ignored since the Ka value is just too small and it also does not follow the five percent criteria.

\(\to 2.27 \times 10^{-11} \times 0.0667 = x_2\\\\\to x_2 = 1.515\times 10^{-12}\\\\\to x = 1.23\times 10^{-6}\ M\\\\\to [H_3O^+] = x = 1.23\times 10^{-6}\ M\\\\\)

We have the formula to calculate pH.

\(\to pH = - \log [H_3O^+] = - \log 1.23\times 10^{-6}\ M= 5.91\)

The pH at the equivalent point for this titration is "5.91".

(b) Qh(dot)=600 kW, Qc(dot)=0 kW  is an impossible process.

(c) Qh(dot)=600 kW, Qc(dot)=200 kW  is a reversible process.

Explanation:

T(hot) = 1200k, T(cold) = 400

efficiency n = (Th - Tc ) / Tc

n = (1200 - 400) / 1200 = 0.667 (this will be the comparison base)

(a)

Qh = 600 kW, Qc = 400 kW

n = (Qh - Qc) / Qh ⇒ (600 - 400) / 600

n = 0.33

0.33 is less than efficiency value from temperature 0.67

∴ it is irreversible process

(b)

Qh = 600 kW, Qc = 0

n = (Qh - Qc) / Qh ⇒ (600 - 0) / 600 = 1

efficiency in any power cycle can never be equal to one.

∴ it is an impossible process.

(c)

Qh = 600 kW, Qc = 200 kW

n = (Qh - Qc) / Qh = (600 - 200) / 600

n = 0.67 (it is equal to efficiency value from temperature)

∴ it is a reversible process
