(T/F) a derived class may become a base class, if another class is derived from it.
True. In object-oriented programming, a derived class can be used as a base class for another class.
When a class is derived from another class, it inherits all of the member variables and methods of the base class. The derived class can then add new member variables and methods, or override existing ones, to create a new class that extends or modifies the behavior of the base class. If another class is derived from the derived class, it will inherit all of the member variables and methods of both the derived class and the original base class. This allows for complex inheritance hierarchies where multiple classes can build upon each other to create more specialized or specific classes. So, the statement "a derived class may become a base class, if another class is derived from it" is true.

Which of the following is not true of the thin client on your desk at your office?
a) It has extensive capabilities.
b) It does not contain a hard disk.
c) It looks like a desktop computer.
d) It accesses data via the Internet.
The correct answer is a) It has extensive capabilities. A thin client is a basic computer terminal that relies on a server to do most of its processing and storage.
Therefore, it does not have extensive capabilities and it is not a powerful computer. It also does not contain a hard disk, as it relies on the server for storage. However, it can look like a desktop computer and access data via the Internet. In contrast to a thick client, which is a powerful computer that can run applications and store data locally, a thin client is designed to be simple and easy to manage.

if a drain cleaner solution is a strong electrolyte, which of the following must be true? A) Drain cleaner is highly reactive.B) Drain cleaner is slightly reactive.C) Drain cleaner is highly ionized.D) Drain cleaner is slightly ionized.E) none of the above
A strong electrolyte is a substance that completely ionizes when dissolved in a solvent, such as water, to form ions that can conduct electricity.
Therefore, if a drain cleaner solution is a strong electrolyte, it means that it contains a high concentration of ions that are able to conduct electricity. This suggests that the solution is highly ionized, as a result of the dissociation of the solute into its constituent ions.
The high degree of ionization indicates that the drain cleaner solution is a powerful cleaning agent, as the ions can react with and dissolve substances that can clog drains. However, this does not necessarily mean that the drain cleaner solution is highly reactive, as the reactivity of the solution depends on the nature of the ions present.
In summary, the correct answer is (C) Drain cleaner is highly ionized, as a strong electrolyte is a substance that ionizes completely in solution. The high degree of ionization suggests that the drain cleaner solution is a powerful cleaning agent, but it does not necessarily imply that the drain cleaner solution is highly reactive, as this depends on the nature of the ions present in the solution.

Before converting a table into 3NF, it is imperative the table already be in ____: 1NF, 2NF, BCNF, or 4NF
The process of normalization in database design involves organizing data in a structured manner to eliminate data redundancy and improve data integrity. Before converting a table into 3NF, it is imperative the table already be in 2NF.
Normalization is usually carried out in multiple steps, with each step building on the previous one. The goal is to ensure that the database tables meet certain normal form criteria. The first normal form (1NF) requires that the table have a primary key and that each column has a single value. The second normal form (2NF) builds on 1NF and requires that all non-key columns are fully dependent on the primary key. The third normal form (3NF) builds on 2NF and requires that all non-key columns are independent of each other.
Therefore, before converting a table into 3NF, it is imperative that the table already be in at least 1NF and 2NF. It is also desirable to have the table in BCNF or 4NF, but it is not necessary for 3NF conversion.

Explanation:
because
from a database design point of view, first normal form is better than second normal form. group of answer choices true false
False. From a database design point of view, second normal form is better than first normal form.
First normal form (1NF) requires that each column in a table must hold atomic values, meaning that each column should contain only one value per row. This eliminates the possibility of storing multiple values in a single column, which can cause data redundancy and inconsistencies.
However, first normal form does not address the issue of dependencies between columns. This is where second normal form (2NF) comes in. 2NF requires that each non-key column in a table must be dependent on the entire primary key, not just part of it. This eliminates the possibility of data redundancy and inconsistencies that can occur when a non-key column is dependent on only part of the primary key.
Therefore, from a database design point of view, second normal form is better than first normal form as it ensures better data organization and reduces the possibility of data anomalies.

if the air compressor develops a leak, what keeps the air in the tanks
If an air compressor develops a leak, the air pressure inside the tanks will gradually decrease over time.
However, there are a few mechanisms that keep the air in the tanks for as long as possible. Firstly, there is a check valve present in the air compressor that prevents the air from flowing back into the compressor when it is not running. This ensures that the air remains in the tanks until it is needed. Additionally, some air compressors also have a pressure switch that activates the motor when the air pressure in the tanks drops below a certain level. This means that the compressor will kick in and refill the tanks with compressed air once the pressure drops. Finally, some models have an automatic drain valve that releases any accumulated moisture in the tanks, preventing corrosion and ensuring that the tanks remain air-tight. In conclusion, while a leak in an air compressor can cause a decrease in pressure, the presence of these mechanisms means that the tanks will still retain some of the compressed air until it is replenished.
