B. Fertile soil would not be considered physical capital.  Physical capital refers to tangible, man-made assets that help in the production process, like tools, machinery, and buildings. Fertile soil, however, is a natural resource and not a man-made asset.

Physical capital refers to tangible assets used in production, such as machinery, tools, equipment, and buildings. These assets are used to create goods and services, and they require an initial investment to acquire.

An axe, a factory, and a forklift are all examples of physical capital because they are tangible assets that are used in production. An axe is a tool that can be used for cutting down trees to make lumber, a factory is a building where goods are manufactured, and a forklift is a machine used to move heavy materials around a factory or warehouse.

Fertile soil, on the other hand, is not a tangible asset that is used in production. While it is certainly important for agriculture and farming, it is not a physical asset that can be used to create goods or services. Instead, it is considered a natural resource that is used in conjunction with physical capital to produce crops and other agricultural products.

The output will be an error message since the input() function in Python always takes input as a string, even if the entered value is an integer like 12.

Here,

It cannot directly concatenate a string with an integer.

In order to fix this, we need to convert the input string into an integer using the int() function,

```

x = int(input())

x = x + "abc" # this will give an error message

```If we fix the code, the correct output will be:

Answer:

Explanation:

From the given information;

There is no change or any difference in velocity in between the inlet and the outlet.

Therefore by using Bernoulli's equation, we have:

\(\dfrac{V_1^2}{2g}+ \dfrac{P_1}{\gamma}+ z_1 + Epump= \dfrac{V_2^2}{2g}+ \dfrac{P_2}{\gamma}+ z_2+ H_L\)

By dividing like terms on both sides, the equation is reduced to:

\(z_1 + E_{pump} = z_2+H_L \\ \\ E_{pump} =(z_2-z_1)+H_L\)

where;

\(\Delta z = 400\)

\(\Delta z = z_2-z_1\)

\(\text{total head loss}= 408.5\)

\(E_{pump} =(400)+408.5\)

\(E_{pump} = 808.5 \ ft\)

The required power input can be determined by using the formula:

\(P= \dfrac{\gamma_wQH_{pump}}{\eta}\)

Assuming the missing pump efficiency = 70% and the flow rate Q= 1.34

Then:

\(P= \dfrac{62.40\times 1.34 \times 808.5}{0.7}\)

\(P = \dfrac{96576.48 \ ft.lb/s}{550\dfrac{ ft*lb/s}{hp}}\)

P = 175.594 hp

The minimum distance that must be maintained below sprinkler heads varies depending on the type of sprinkler system. However, in general, the distance should not be less than 18 inches or more than 24 inches.

The National Fire Protection Association (NFPA) sets the standards for fire safety in the United States. According to their guidelines, the minimum distance that must be maintained below sprinkler heads is 18 inches. This applies to both wet and dry sprinkler systems. Wet sprinkler systems are the most common type and use water to extinguish fires. Dry sprinkler systems, on the other hand, use pressurized air or nitrogen to expel water when a fire is detected.
It's important to note that some sprinkler systems have specific requirements that must be met. For example, some dry sprinkler systems require a minimum distance of 24 inches below the sprinkler heads. Additionally, some systems may require a higher distance if there are obstructions present.
The reason for maintaining a minimum distance below sprinkler heads is to ensure that the water is dispersed properly in the event of a fire. If the distance is too close, the water may not be able to cover the intended area, which could result in the fire not being fully extinguished.

The minimum distance that must be maintained below sprinkler heads is generally 18 inches, but it may vary depending on the type of sprinkler system and any specific requirements set by the manufacturer. It's essential to follow these guidelines to ensure that the sprinkler system functions correctly in the event of a fire and helps to prevent property damage and injuries.

In transonic flight, when encountering strong normal shock waves, the turbulent airflow generated by these shockwaves can lead to a phenomenon known as a shock stall. This term is used because the effects observed during this event are comparable to the effects experienced during a normal low speed stall or a high angle of attack stall, both of which are caused by the separation of airflow.

The main reason for the common use of a 3-phase 4-wire system is the need to deliver power to different types of loads efficiently and effectively.

A 3-phase 4-wire system provides three alternating currents that are 120 degrees out of phase with each other. This type of system is commonly used in industrial and commercial settings because it can handle higher power loads than single-phase systems. The fourth wire is a neutral wire, which provides a return path for any unbalanced current in the system. This is important because it ensures that the voltage across each load remains balanced, which is necessary for the proper functioning of electrical equipment. Additionally, the use of a 3-phase system allows for the use of smaller and more efficient motors, reducing energy consumption and costs. Overall, the use of a 3-phase 4-wire system is essential for delivering power effectively and efficiently to various types of loads.

Explanation:

µ represents \(10^{-6}\). Multiply this by 6,950.

The system's temperature is maintained constant using an isothermal process, which is a type of thermodynamic process. Thermal equilibrium is maintained because heat is introduced or removed from the system so gradually.

Any isothermal process must have zero change in internal energy since the change in internal energy depends on the change in temperature, which is zero for all isothermal processes.

Since the temperature is kept constant, the energy change is zero (U=0). Thus, the work that the ideal gas does on its surroundings is equal to the heat that the gas absorbs.

Therefore, In a closed system, refrigerant-134a undergoes an isothermal procedure at 320 kPa and 40 °C until its quality reaches 45%. Determine the effort and heat transfer needed on a per-unit-mass basis. 2: 40.6 kJ/kg and 130 kJ/kg.

To find the state of stress at point A, we need to use the principle of superposition. This principle allows us to determine the combined effect of multiple loadings on a structure or object.

To find the stress σa at point A due to all of the loadings on the rod, we need to consider each loading separately and then sum up the individual stresses.

1. Identify the different loadings acting on the rod: For example, the rod might be subjected to axial forces, bending moments, or shear forces. Each loading will have its own effect on the stress at point A.

2. Determine the stress at point A due to each loading: Using the appropriate equations or principles for each type of loading, calculate the stress at point A caused by each loading separately.

3. Sum up the individual stresses: Add up the stresses at point A caused by each loading to find the total stress at that point. This is done by applying the principle of superposition, which states that the total effect is the sum of the individual effects.

4. The resulting stress σa at point A is the total stress caused by all the loadings acting on the rod.

Answer:

10.203 Volts

Explanation:

For this problem, we need to understand that a series resistive circuit is simply a circuit with some type of voltage source and some resistors, in this case, R1 and R2.

First, we need to find the voltage in the circuit.  To do this, we need to find the total resistance of the circuit.  When two resistors are in series, you sum the resistance.  So we can say the following:

R_Total = R1 + R2

R_Total = 570 Ω + 560 Ω

R_Total = 1130 Ω

Now that we have R_Total for the circuit, we can find the voltage of the circuit by using Ohm's law, V = IR.

V_Total = I_Total * R_Total

V_Total = 17.9 mA * 1130 Ω

V_Total = 20.227 V

Now that we have V_Total, we can find the voltage drop across each resistor by using Ohm's law once more.  Note, that since our circuit is series, both resistors will have the same current (I.e., I_Total = I_1 = I_2).

V_Total = V_1 + V_2

V_Total = V_1 + I_2*R2

V_Total - I_2*R2 = V_1

20.227 V - (17.9 mA * 560 Ω) = V_1

20.227 V - (10.024 V) = V_1

10.203 V = V_1

Hence, the voltage drop across R1 is 10.203 Volts.
