Explanation:

To write a function named abs_sum that takes a list of integers as a parameter and returns the sum of the absolute values of each element in the list, we can use Python's functional programming constructs, such as map and reduce. Here is the solution:

```python
from functools import reduce

def abs_sum(lst):
 # Use map to apply the absolute value function to each element in the list
 abs_lst = map(abs, lst)
 # Use reduce to sum the absolute values in the list
 result = reduce(lambda x, y: x + y, abs_lst, 0)
 return result
```

For example, the absolute sum of [-1, 2, -4, 6, -9] is 22:

```python
print(abs_sum([-1, 2, -4, 6, -9])) # 22
```

If the list is empty, the function will return 0:

```python
print(abs_sum([])) # 0
```

This solution does not use any loops or recursion, as required in the question.

Whether the object on the right will move out by 1cm when the plunger on the left is pushed in depends on several factors, including the size of the syringes and the tube, the volume of water in each syringe, and the properties of the object on the right.

Assuming that the syringes and the tube are of equal size and are connected by a watertight seal, and that the object on the right is not affected by the pressure changes caused by pushing in the plunger on the left, then the answer is yes - the object on the right should move out by 1cm.When the plunger on the left is pushed in, the volume of water in that syringe decreases, causing a corresponding decrease in the volume of water in the tube. This decrease in volume creates a decrease in pressure, which should cause the object on the right to move out by a distance equal to the decrease in volume.However, it's worth noting that in practice, there may be other factors that affect the movement of the object, such as friction in the syringes and the tube, or the compressibility of the water.

The non-comparative sorting algorithm that is unstable is 'pigeonhole sort.'Pigeonhole sort is a sorting algorithm that is non-comparative and linear.

Its worst-case and average-case performance are both O(n+Range) in the case of an integer sort, where 'Range' is the largest difference between any two elements in the list. The algorithm is simple to implement and is best suited for integer sorting in the linear time complexity range.Pigeonhole sort, also known as a bin sort or a counting sort, is a type of sorting algorithm.

The algorithm is simple and is often used for sorting small data sets. It's a non-comparative sorting algorithm, which means it doesn't rely on the comparison operation to compare objects.The pigeonhole sort algorithm divides the input array into pigeonholes. It is based on the fact that if n items are put into m containers, where m < n, at least one container must contain more than one item.

Based on the information provided, the most likely cause of the wireless communication errors faced by Black Lion Cements' network engineers is interference. Option (A) " interference seems to be the cause" is the correct answer.

The heavy pieces of machinery operating adjacent to the office could generate electromagnetic interference that disrupts the wireless signals, leading to communication errors.

Insufficient wireless coverage could also be a potential cause, but since the office is adjacent to the manufacturing unit, it is unlikely to be the main reason for the communication errors.

Attenuation due to distance or obstacles could also cause signal loss, but this is less likely since the network engineers are facing wireless communication errors, rather than complete signal loss.

The lack of firmware updates is another potential cause of network errors, but it is less likely to be the primary cause of the wireless communication errors that Black Lion Cements is facing.

The metrics for finding dissimilarity between two clusters in hierarchical clustering are single linkage, complete linkage, and average linkage.

Hierarchical clustering is a type of data clustering method that builds a hierarchy of clusters that resemble a tree-like structure or a dendrogram. The methods for building this hierarchy are divided into two types: agglomerative and divisive. In hierarchical clustering, we have several metrics for determining dissimilarity between two clusters. The most commonly used ones are:

Single linkage, also known as the nearest neighbor method, compares the closest points between two clusters. It connects the two closest points from each cluster and forms a new cluster. This approach is a faster method, but it is sensitive to noise and tends to create long chains.

Complete linkage, also known as the farthest neighbor method, compares the farthest points between two clusters. It connects the two farthest points from each cluster and forms a new cluster. This method is less sensitive to noise and tends to produce compact clusters, but it is slower than the single linkage method.

Average linkage calculates the average distance between all pairs of data points in two different clusters. It then connects the two clusters that have the smallest average distance. This method is slower than single linkage but is more robust to noise and outliers.

To ensure that text is easily read on low resolution devices, we should use a higher x-height. This statement is true.

What is an x-height?

The distance between the baseline of a line of type and the top of the main body of lower case letters is referred to as x-height. The x-height is a critical aspect of text readability, particularly in body copy. It determines the visual impact of a typeface and its legibility in smaller sizes.

Resolution and higher x-heightResolution has an impact on the visual quality of typefaces. As the resolution gets lower, typefaces become more difficult to read. The x-height is increased to make text more readable on low-resolution devices. When we use a typeface with a higher x-height, the size of lowercase letters is increased. This implies that the height of lowercase letters is closer to the height of uppercase letters.

As a result, lower-case letters appear larger, and the words appear to have more space between them. In conclusion, to ensure that text is easily read on low-resolution devices, we should use a higher x-height.

The IPv4 address class of 221.1.2.3 is Class C. The IPv4 protocol uses address classes to define the size of the network portion of the address and the number of hosts that can be assigned to it.

The first octet of the IP address determines the address class. Class C addresses have their first three bits set to 110 and the fourth bit set to 0, which allows for 24 bits to be used to define the network portion of the address. This means that Class C networks can support up to 256 (2^8) hosts per network and are commonly used in small to medium-sized businesses.In computer networking, an IPv4 address is a unique identifier assigned to devices on a network using the Internet Protocol version 4. IPv4 addresses are 32-bit binary numbers that are typically represented in human-readable format as a series of four decimal numbers separated by periods. Each of these decimal numbers represents a byte of the binary number, with values ranging from 0 to 255. IPv4 addresses are divided into classes based on the range of values in the first byte, with Class A addresses having a range from 1 to 126, Class B addresses from 128 to 191, and Class C addresses from 192 to 223. The remaining address ranges are reserved for special purposes, such as multicast or private networks.

               # Apply f1, f2, and f3 in a cycle depending on the value of i
               if i % 3 == 0:
                   result = f1(result)
               elif i % 3 == 1:

Java is mainly used for application programming. It is widely used in Windows-based, web-based, enterprise, and mobile applications.

C++ uses compiler only. C++ is compiled and run using the compiler which converts source code into machine code so, C++ is platform dependent.

Java uses both compiler and interpreter. Java source code is converted into bytecode at compilation time. The interpreter executes this bytecode at runtime and produces output. Java is interpreted that is why it is platform-independent.

C++ is an object-oriented language. However, in the C language, a single root hierarchy is not possible.

Java is also an object-oriented language. However, everything (except fundamental types) is an object in Java. It is a single root hierarchy as everything gets derived from java.lang.Object.
