The correct clause to add to the SQL query to retrieve only the first 12 records is "LIMIT 12". The correct option is c.

The domain-specific programming language known as SQL is used for managing data stored in relational database management systems or for stream processing in relational data stream management systems.

"LIMIT 12" is the appropriate clause to include in the SQL query to only return the first 12 records. Thus, the whole SQL query would be:

speaker selection from the keynote table LIMIT 12 WHERE knowledge = "zoology"

Just the top 12 entries that satisfy the constraint "expertise = 'zoology'" will be returned by this query.

Thus, the correct option is c.

Your question seems incomplete, the probable complete question is:

You are querying a database of keynote speakers to determine who has expertise in zoology. For your project, you only need the first 12 records.

What clause should you add to the following SQL query?

SELECT speakers FROM keynote_table WHERE expertise = "zoology"

a. LIMIT, 12

b. LIMIT = 12

c. LIMIT 12

d. LIMIT_12

The decimal values of a and b are 7 and 11, respectively. The sum of a and b is 18, which is equivalent to the binary value of 10010. The sum obtained by the full adder is 10010 as well.

The full adder circuit takes three binary inputs, which are two bits of numbers to be added and the carry-in value, and outputs a sum and a carry-out value.

The table below shows the result of adding 0111 and 1011 using a full adder.

a b c_in    s    c_out

0 1  0    1       0

1 1  1    1       1

1 0  1    0       1

0 1  1    0       1

The decimal values of a and b are 7 and 11, respectively. The sum of a and b is 18, which is equivalent to the binary value of 10010. The sum obtained by the full adder is 10010 as well. Thus, the answers are the same. The full adder circuit is an essential building block in digital circuits, and it is used in many applications, such as arithmetic logic units, microprocessors, and digital signal processing.

The overall entropy of a system may only ever increase or stay constant during spontaneous processes, according to the second law of thermodynamics.

According to the second rule of thermodynamics, entropy does not decrease in a closed system.

In other words, if the system is originally in an ordered, low-entropy state, its condition will tend to naturally drift toward a maximum-entropy state (disorder).

The first alternating current (AC) electric system was developed by Nikola Tesla. In the late 19th century.

What is alternating current (AC)?

Alternating current (AC) is a type of electrical current that periodically reverses its direction of flow. In an AC circuit, the flow of electrons alternates back and forth between the two wires of the circuit, creating a waveform that varies with time. The voltage and current in an AC circuit oscillate sinusoidally, with a frequency that is measured in hertz (Hz).

AC power is used to transmit electrical energy over long distances, and is the standard for electrical power distribution in most parts of the world. AC power can be easily transformed into different voltages using transformers, which makes it more efficient and practical for use in power grids. AC power can also be used to drive AC motors, which are commonly used in a wide range of industrial and household applications.

Tesla worked for the inventor and businessman Thomas Edison, who was promoting direct current (DC) as the standard for electrical power distribution. However, Tesla believed that AC was a more efficient and practical system, and in the 1880s he began developing his own AC motors and generators. In 1887, he designed the first AC induction motor, which was a key innovation in the development of AC power systems. Tesla also worked with George Westinghouse, who was a strong proponent of AC power, to promote and develop AC technology. In the late 1890s,

Therefore,  AC power systems began to replace DC systems as the standard for electrical power distribution, thanks in large part to the work of Tesla and his collaborators.

False, DBMS selection should be done before the logical design stage in the database design process.

The selection of a Database Management System (DBMS) should be done before the logical design stage of the database design process. This is because different DBMSs have different features, functionalities, and constraints, which can affect the design decisions made during the logical design stage.

During the logical design stage, the focus is on defining the data requirements, entities, relationships, and constraints of the database, without consideration for the specific features of a particular DBMS. Once the logical design is complete, the physical design stage begins, which involves translating the logical design into a physical database schema that can be implemented using a specific DBMS.

Therefore, the selection of a DBMS should be done before the logical design stage, as it can influence the design decisions made during the entire database design process, from the requirements analysis to the physical implementation of the database.

We can combine simpler Boolean expressions to create more complicated Boolean expressions using the three logical operators and, or, and not.

These operators have the same semantics (meaning) as their English equivalents. For instance, x > 0 and x 10 only returns True if x is both more than 0 and less than 10. If any of the requirements, i.e., whether the number n is divisible by 2 or by 3, is true, then n% 2 == 0 or n% 3 == 0 is true.

A Boolean value is negated by the not operator, therefore not (x > y) is True if x > y is False, or if x is less than or equal to y. We can combine simpler Boolean expressions to create more complicated Boolean expressions using the three logical operators and, or, and not.
