The proof by induction is a common method used in mathematics to prove statements about natural numbers. It involves establishing a base case and then proving the inductive hypothesis for all subsequent cases.

To prove that Vi > 1, (L*) = L*, we will use induction. We want to show that this statement holds true for all natural numbers.

Basis: Let n = 1. Then, Vi = 2 and (L*) = L*. Clearly, Vi > 1, so the base case holds.

Inductive Hypothesis: Assume that for some k > 1, Vi > 1 and (L*) = L* for all n ≤ k.

Complete the rest of the proof: We want to show that Vi > 1 and (L*) = L* for n = k + 1.

For Vi > 1, note that Vi is defined as the number of vertices in a graph with a minimum degree of i. Since the graph has at least k + 1 vertices, there must be at least one vertex with degree k or greater. Thus, we have Vi > 1.

For (L*) = L*, let G be a graph with minimum degree of k + 1. By the inductive hypothesis, any graph with minimum degree of k must satisfy (L*) = L*. Since every vertex in G has degree at least k + 1, we can remove any vertex and still have a graph with minimum degree of k. By the inductive hypothesis, this new graph will satisfy (L*) = L*. But since we removed a vertex with degree k + 1, we have also removed at least k + 1 edges. Thus, (L*) = L* for G as well.

By induction, we have shown that Vi > 1 and (L*) = L* for all natural numbers n.

When two vehicles arrive at stop signs in an intersection at the same time, the general rule is that the vehicle on the right has the right of way. This is known as the "right-hand rule."

In other words, the driver of the vehicle on the left must yield to the driver of the vehicle on the right. If both vehicles arrived at the same time and are at the same position relative to the intersection, the driver on the left should yield to the driver on the right.

It's important to note that this rule applies only to intersections with stop signs. At intersections with traffic lights or other traffic control devices, the right-of-way rules may be different. In addition, there may be specific state or local laws that govern right-of-way rules in certain situations.

The answer to this question is D. The energy used is the same for both segments, the power while running is greater.

To explain this answer, it's important to understand the definitions of energy and power. Energy is the ability to do work, while power is the rate at which work is done.

During the walking segment of the journey, the person is expending energy to move their body 1 km. This requires a certain amount of work to be done, which translates to a certain amount of energy being used. However, because the person is walking at a slower pace, the rate at which work is being done (power) is lower.

During the running segment of the journey, the person is again expending energy to move their body the same 1 km distance, but they are doing so at a faster pace. This means that the rate at which work is being done (power) is higher.

So while the energy used is the same for both segments (1 km worth of energy), the power during the running segment is greater. This is because the person is doing the same amount of work in a shorter amount of time, which requires a higher rate of power.

a) To calculate the real and reactive power associated with each circuit element in the circuit shown in Fig. P9.63, we need to use the given voltages and the impedance values of the elements. For element a, we have a resistance of 10 ohms and a reactance of 20 ohms, so the real power is P = V^2/R = (60^2)/10 = 360 W and the reactive power is Q = V^2/X = (60^2)/20 = 180 VAR. For element b, we have a resistance of 5 ohms and a reactance of -10 ohms, so the real power is P = V^2/R = (90^2)/5 = 1620 W and the reactive power is Q = V^2/X = (90^2)/(-10) = -810 VAR.

b) To verify that the average power generated equals the average power absorbed, we need to find the average power for each element and then compare them. The average power is given by P_avg = (1/T)*∫(0 to T) P(t) dt, where T is the period of the waveform. Since both waveforms have a period of 1/40,000 seconds, we can calculate the average power for each element using this formula. For element a, the average power is 0 W since it is an inductor and does not dissipate power. For element b, the average power is P_avg = (1/2)*(1620 W) = 810 W. Therefore, the average power generated by element b equals the average power absorbed by it.

c) To verify that the magnetizing VARs generated equal the magnetizing VARs absorbed, we need to calculate the reactive power associated with the inductor and the capacitor in the circuit. The inductor and capacitor form a resonant circuit, so the reactive power will be continuously exchanged between them. The magnetizing VARs generated by the inductor are Q_L = V_L^2/X_L = (60^2)/(20) = 180 VAR, where X_L is the inductive reactance. The magnetizing VARs absorbed by the capacitor are Q_C = V_C^2/X_C = (90^2)/(10) = 810 VAR, where X_C is the capacitive reactance. Since the magnitudes of these reactive powers are equal and opposite, we can say that the magnetizing VARs generated by the inductor equal the magnetizing VARs absorbed by the capacitor.

At the interface between atmosphere air and water, the composition of the air and water molecules will depend on various factors such as temperature, pressure, and the surrounding environment. At 17 C, the mole and mass fraction of water at the air side of the interface would be relatively low compared to that of the water side of the interface.

This is because the air can only hold a limited amount of water vapor at this temperature, and any excess water molecules would condense to form droplets on the surface of the water.

Similarly, the mole and mass fraction of oxygen at the air side of the interface would be higher than that of the water side of the interface. This is because oxygen is more soluble in water than in air, and therefore, more oxygen molecules would dissolve into the water at the interface.

Assuming the atmosphere air contains 20.5% oxygen by volume, the mole fraction of oxygen at the air side of the interface would be approximately 0.205. The mass fraction of oxygen can be calculated using the molecular weight of oxygen (32 g/mol) and the density of air and water. Overall, the interface between atmosphere air and water at 17 C is a dynamic system that involves the continuous exchange of molecules between the two phases.

The NOx concentration in parts per billion by volume (ppbv) can be calculated based on the atmospheric mass concentrations of nitrogen monoxide (NO) and nitrogen dioxide (NO2).

To convert the mass concentrations to volume concentrations, we need to consider the ideal gas law, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature. Since we are assuming a temperature of 30°C and pressure of 1 atm, we can calculate the volume concentrations of NO and NO2 at these conditions. The ideal gas law can be rearranged to express the number of moles (n) as n = PV / RT.

Next, we convert the mass concentrations to a number of moles using the molar mass of each gas. The molar mass of NO is 30.01 g/mol, and the molar mass of NO2 is 46.01 g/mol.

Using the given mass concentrations (90 μg/m3 for NO and 120 μg/m3 for NO2) and the molar masses, we can calculate the number of moles for each gas. Finally, we can determine the NOx concentration in ppbv by summing the volume concentrations of NO and NO2 and expressing it as parts per billion by volume. However, without the exact volume or area over which these concentrations are measured, we cannot provide the specific numerical value for the NOx concentration in ppbv.

In linear elasticity theory, a state of pure shear refers to a deformation in which the material is subjected to two equal and opposite forces that act parallel to each other, but in different directions. This causes the material to deform by sliding its planes of atoms relative to each other, without changing its volume.

To show that a state of pure shear leads to no volume change, we can consider a small cube of material before and after deformation. Let's assume that the material is isotropic and homogeneous, and that the deformation is small enough to be described by the linear elastic theory.

Before deformation, the cube has a volume V, given by V = l x w x h, where l, w, and h are the dimensions of the cube. Let's assume that the shear deformation is applied in the x-y plane, with the x-direction being the direction of the applied force and the y-direction being perpendicular to it.

During pure shear deformation, the cube is distorted in the x-y plane, while the height of the cube remains unchanged. Let's assume that the deformation causes the top face of the cube to move a distance d to the right, and the bottom face of the cube to move a distance d to the left. The deformation in the y-direction is zero.

The new dimensions of the cube are: length = l + d, width = w - d, and height = h. The new volume of the cube is:

V' = (l + d) x (w - d) x h

Expanding this expression, we get:

V' = lwh + dh - dl - d^2h

Since the deformation is small, we can assume that d^2 is negligible compared to d. Therefore, we can simplify the expression as follows:

V' ≈ lwh + dh - dl

The change in volume, ΔV, is given by:

ΔV = V' - V = dh - dl

Since the deformation is pure shear, the strain in the y-direction is zero, and the strain in the x-direction is given by:

εx = dl/l = -dy/w

where dy is the displacement in the y-direction. Therefore, we can rewrite the change in volume as:

ΔV = dh + wεxh

Since εx is negative, we have:

wεxh = -wydh/w = -dyh

Substituting this into the expression for ΔV, we get:

ΔV = dh - dyh = h(d - dy)

Since the deformation is pure shear, d = dy, and therefore ΔV = 0.

Thus, we have shown that a state of pure shear leads to no volume change during linear elastic deformation.

Lastly, if the function is called without a matching connection.close() call, it can also cause an exception. This is because it is important to properly close the connection to the database after use to prevent memory leaks and other issues.

In conclusion, the mysql.connector.connect() function may throw an exception in a Connector/Python program due to various reasons, including incorrect credentials, missing statements, and improper usage.

Pressure is a physical quantity that describes the force applied per unit area on a surface. The pressure drop across the valve is 6.39 psi.

Density = specific gravity x density of water = 0.89 x 62.4 lb/ft³ = 55.536 lb/ft³

Volume flow rate = 26 gal/min = 26/7.481 ft³/min = 0.0034781 ft³/s

Mass flow rate = volume flow rate x density = 0.0034781 ft³/s x 55.536 lb/ft³ = 0.1931 lb/s

Now we can plug in the values into the energy balance equation:

(0.1931 lb/s) x (0.49 Btu/(lb degree F)) x (4 degrees F) = (pressure drop) x (0.0034781 ft³/s) x (0.89)

Simplifying and solving for pressure drop:

Pressure drop = (0.1931 lb/s) x (0.49 Btu/(lb degree F)) x (4 degrees F) / (0.0034781 ft³/s) x (0.89)

= 6.39 psi
