To create a DataFrame called 'individuals' containing only the 'individuals' column of 'homelessness' and print the head of the result, you should follow these steps:

1. Select the 'individuals' column from the 'homelessness' DataFrame.
2. Create a new DataFrame named 'individuals' containing the selected column.
3. Print the head of the newly created DataFrame.

Here's the code:

```python
import pandas as pd

# Assuming you have a DataFrame called 'homelessness'
# Select the individuals column
individuals = homelessness[['individuals']]

# Print the head of the result
print(individuals.head())
```

In this code, we use double brackets `[['individuals']]` to select the 'individuals' column as a DataFrame. Then, we use the `head()` method to print the first 5 rows of the 'individuals' DataFrame.

The process is called virtualization, where the CPU (such as Intel or AMD) allows for the creation of virtual machines that can run multiple operating systems simultaneously.

How can we explain this?

The process of running more than one operating system at the same time on a computer with built-in support is called virtualization. Intel and AMD have both developed hardware-level support for virtualization, which allows a computer to run multiple operating systems simultaneously, each in its own virtual environment.

Intel's virtualization technology is called Intel Virtualization Technology (Intel VT), while AMD's virtualization technology is called AMD Virtualization (AMD-V). These technologies provide support for running virtual machines (VMs) that are isolated from the host operating system and can run their own guest operating systems.

Virtualization is widely used in data centers and cloud computing environments to optimize the use of hardware resources and increase the efficiency of computing infrastructure. It also allows for the easy creation and management of virtual environments for testing, development, and other purposes.

The two differences and two similarities between a bubble sort and a selection sort when sorting an array of 10 elements are as follows: Bubble sort works by repeatedly swapping and Both bubble sort and selection sort are comparison-based sorting algorithms.

The two differences and two similarities between a bubble sort and a selection sort when sorting an array of 10 elements are as follows:

Differences:
1. Bubble sort works by repeatedly swapping adjacent elements if they are in the wrong order, while selection sort works by selecting the smallest element in the remaining unsorted part of the array and swapping it with the current element being evaluated.
2. Bubble sort can be more efficient for nearly sorted lists since it can stop early if no swaps are made in a complete pass, whereas selection sort always goes through the entire array for each iteration.

Similarities:
1. Both bubble sort and selection sort are comparison-based sorting algorithms, meaning they rely on comparing elements in the array to determine their relative positions.
2. Both algorithms have a worst-case and average time complexity of O(n^2), making them inefficient for large datasets but suitable for smaller lists, such as an array of 10 elements.

With a rated 240 V, a 10 kW heating element would unsurprisingly yield approximately 34,121.42 BTU/h.

To determine the power of a 10 kW heating element functioning at a constant 240 V in BTU/h (British Thermal Units per hour), we must initially convert from kilowatts to watts and then use an appropriate conversion factor.

1 kW = 1,000 W

So, 10 kW equates to 10,000 W

To arrive at BTU/h, we can apply the following conversion factor:

1 W = 3.412142 BTU/h

Thus, by multiplying the wattage amount with the conversion rate, we come up with the total BTU/h output:

BTU/h = 10,000 W * 3.412142 BTU/h/W = 34,121.42 BTU/h

Normal-order and applicative-order evaluation are two different strategies used for evaluating expressions in programming languages.

Normal-order evaluation involves evaluating the arguments of a function before the function itself is evaluated. This means that any arguments that are not used by the function are still evaluated. Normal-order evaluation is sometimes called "call-by-name" evaluation.

Applicative-order evaluation, on the other hand, involves evaluating the function arguments before the function itself is evaluated. This means that any arguments that are not used by the function are not evaluated. Applicative-order evaluation is sometimes called "call-by-value" evaluation.

Lazy evaluation is a strategy where expressions are only evaluated when they are needed. This means that if an argument is not used by a function, it will not be evaluated. Lazy evaluation can be thought of as a combination of normal-order and applicative-order evaluation because it evaluates expressions only when they are needed, like normal-order evaluation, but evaluates function arguments before the function itself, like applicative-order evaluation.

Overall, the choice between normal order, applicative order, and lazy evaluation depends on the specific programming language and the specific use case. Each strategy has its advantages and disadvantages, and programmers must carefully consider which one to use in each situation.

Result:

The pressure in the cap end of the cylinder when extended at a constant velocity = ≈ 14,636 psi.

We can calculate the pressure in the cap end of the cylinder when extended at a constant velocity by:

Given:

Cylinder bore diameter = 2 inches

Load weight = 1,615 lbs

Coefficient of friction = 0.13

Slope angle = 28 degrees

Calculate the force of gravity on the load:

Load force = Load weight * acceleration due to gravity

Load force = 1,615 lbs * 32.2 ft/s² (acceleration due to gravity)

Load force = 51,943 lbs

Calculate the frictional force on the load:

Normal force = Load force * cos(slope angle)

Normal force = 51,943 lbs * cos(28 degrees)

Normal force = 46,151 lbs

Frictional force = Coefficient of friction * Normal force

Frictional force = 0.13 * 46,151 lbs

Frictional force = 5,999 lbs

Calculate the net force on the cylinder:

Net force = Load force - Frictional force

Net force = 51,943 lbs - 5,999 lbs

Net force = 45,944 lbs

Calculate the pressure in the cap end of the cylinder:

Cap end area = pi * (Cylinder bore diameter / 2)²

Cap end area = 3.14 * (2 inches / 2)²

Cap end area = 3.14 square inches

Pressure = Net force / Cap end area

Pressure = 45,944 lbs / 3.14 square inches

Pressure = 14,636 psi

Therefore, the pressure in the cap end of the cylinder when extended at a constant velocity = ≈ 14,636 psi.

We would expect the flow to be turbulent since the Reynold's number is greater than 4000

To know whether the flow through the 3-ft-diameter pipe is laminar or turbulent, we will have to calculate the Reynolds number using the formula:

Re = (ρVD) / μ

where:

Re is the Reynolds number

ρ is the density of the fluid

V is the velocity of the fluid

D is the diameter of the pipe = 3 ft

μ is the dynamic viscosity of the fluid

Assuming that the pipe is completely filled with water and the water is flowing steadily, the velocity of the water can be calculated using the continuity equation:

Q = A * V

where:

Q is the volumetric flow rate of the water

A is the cross-sectional area of the pipe

V is the velocity of the water

We can assume that the flow rate is equal to the rainfall rate, which is typically measured in inches per hour (in/hr) or millimeters per hour (mm/hr). For example, if the rainfall rate is 1 inch per hour, then the volumetric flow rate of water can be calculated as follows:

Q = (1 in/hr) * (3.14 ft² / 12² in²) * (1/12 ft/in) = 0.0667 ft³/s

Next, we can calculate the cross-sectional area of the pipe as follows:

A = (π / 4) * D² = (π / 4) * (3 ft)² = 7.07 ft²

Now we can use the continuity equation to calculate the velocity of the water:

V = Q / A = (0.0667 ft³/s) / (7.07 ft²) = 0.0094 ft/s

Finally, we can calculate the Reynolds number using the formula:

Re = (ρVD) / μ

where

ρ = density of water at room temperature = 62.4 lb/ft³

μ = dynamic viscosity = 3.15 × 10⁻⁷ lb·s/ft²

Plugging in these values and the velocity we calculated above, we get:

Re = (ρVD) / μ = (62.4 lb/ft³) * (0.0094 ft/s) * (3 ft) / (3.15 × 10⁻⁷ lb·s/ft²) = 177,142

Since Re is greater than 4000 then the flow is turbulent.
