Let’s assume the meaning of the statement is to compute the thing on the right and store the result into the thing on the left. (This matches most common high-level languages, but in some languages, this might just as easily have been a comparison rather than an assignment.) Let’s further assume that all the letters are variables, all of them have the same data type, the data types are numeric, and the +, /, and parentheses operators all have the typical algebraic meanings for numeric expressions. (In some languages and/or with some data types, the + might mean concatenation instead of addition, etc.)

If your goal is to implement the assignment statement in a common high-level language, the statement itself should be just fine as pseudocode:

• S = (A + B + C) / Y

But the variable names here are not very descriptive. Both in pseudocode and in actual code, it would be best to use variable names that reflect what the variables actually contain. Since I don’t know what your formula represents, I won’t suggest specific names.

If you want to be explicit about the order in which everything happens, then a pseudocode description might look something like:

• Compute the sum of A, B, and C, storing the result into T.
• Compute the quotient T divided by Y, storing the result into S.

I introduced T as a temporary variable.

If your goal were to implement the assignment statement in an assembly language, you might want to break it down further into the individual steps, which would better map to your target language. In this case, the pseudocode might be something like:

• ADD A and B, storing the result into T.
• ADD T and C, storing the result into T.
• DIVIDE T by Y, storing the result into S.

Or even more detail that gets even closer to what’s actually happening at the low level in your target system:

• FETCH A into R1.
• FETCH B into R2.
• ADD R1 and R2, storing the result into R1.
• FETCH C into R2.
• ADD R1 and R2, storing the result into R1.
• FETCH Y into R2.
• DIVIDE R1 by R2, storing the result into R1.
• STORE R1 into S.

I introduced two temporaries here, R1 and R2, which might map to CPU registers in the actual assembly language code.

Pseudocode can vary widely and be used for many different purposes. So, you need to figure out the goal of the pseudocode, and choose a level of abstraction and detail that serves that goal. And follow the pseudocode guidelines you’ve been given, if any.

By the way, writing pseudocode after your write the actual code is like writing an outline an outline after you've written the book report. The act of writing pseudocode has a lot less value, if you’ve already written the actual code.

V = q / C =

                               (150+150)×10^-6

                              4πε₀(20+10)×10^-2 

= 9 × 10⁶ V

So, Option (a) is correct.

In steady state , the capacitors are fully charged and no current pass through them. So no current also pass through resistors 4 ohm and 5 ohm. Thus, the potential across the capacitors will be 2V. 

Energy stored in 5μF capacitor is U_5​ = 1/2 ​× 5 × 2² = 10J

Energy stored in 4μF capacitor is U₄ ​= 1/2 × 4 × 2² = 8J

Thus, U₅​/U₄ ​= 10/8 = 5/4

Correct option is B) extra

Correct answer will be,  b)Extra

y = log₁₀(-1 + 1 + |x - 1/2|)

To defined log x, we have

-1 + |x - 1/2| > 0

⇒ |x - 1/2| > 1

⇒ x - 1/2 > 1 or x - 1/2 < - 1

⇒ x > 3/2 or x < -1/2

⇒ x \(\in\) (\(-\infty, \frac{-1}2\)) U (3/2, \(\infty\))

Domain of y is (-\(\infty\), -1/2) U (3/2, \(\infty\))

f^-1\((\frac{1}{x+1})=3x+4\)

\(\therefore\) f^-1\(\left(\cfrac{1}{\frac{1-x}x+1}\right)\) = 3\((\frac{1-x}x+4)\)

⇒ f^(-1)(x) = 3\((\frac{1-x}x)+4\)---(1)

Let f^-1 = y

⇒ f(y) = x

\(\therefore\) From (1), we get

y = \(3(\frac{1-x}x)+4\)

⇒ \(\frac{x(y-4)}3=1-x\) 

⇒ x + x/3(y - 4) = 1

⇒ x (1 + \(\frac{y-4}3\)) = 1

⇒ x \((\frac{3+y-4}3)=1\)

⇒ x (\(\frac{3+y-4}3\)) = 1

⇒ x = 3/y-1

⇒ f(y) = 3/y-1

\(\therefore\) f(x) = 3/x-1

1. Genetic code is triplet: Each codon consists of sequence of three nitrogen bases. 

2. Genetic code is universal: A particular codon codes for the same amino acid in all organisms. 

3. Genetic code is non overlapping: The successive triplet codons are read in order without overlapping and they do not share any base. 

4. Genetic code is degenerate: A single amino acid is coded by more than one codon. 

Eg: valine is coded by 4 different codons GUA, GUC, GUU and GUG 

5. Genetic code is commaless: Codons are without punctuation and written in linear form. There is no signal to indicate the end of one codon or beginning of the next codon. 

6. Genetic code is non-ambiguous: Each codon specifies a particular amino acid in all organisms. 

Eg: AUG codes for methionine 

7. Initiator codons: Protein synthesis is always initiated by particular codons called initiator codons. 

Eg: AUG in eukaryotes, GUG in prokaryotes 

8. Terminator codons: Three codons that act as stop signals to terminate protein synthesis are called terminator codons or nonsense codons.

Haemophilia is a rare bleeding disorder in which the blood doesn’t clot normally.

GDS have evolved form first computer based reservation systems implemented by several U.S. airlines in the late 1960s and early 1970s. 

• This distributed system was paralleled by increases in computing and storage power; by 1978, SABRE was available in over 130 locations and could store 1 million airfares. 
• After deregulation in 1978, the importance of computerized reservation systems became even more apparent. Further, a CRSs owned by a particular airline could be programmed to display their airline’s information ahead of their competitors in an effort to distort consumer choice.
•  This was compounded by the natural tendency to travel agents to book tickets with the carriers providing the CRS terminals - known as the “halo-effect”. As a result in 1984 the civil Aeronautics Board began to regulate these systems to insure a free and competitive market for both travelers and airlines. 
• By the early 1990s, CRSs had evolved into more complex systems. In part, this was motivated by strategic alliances and mergers between U.S. and European carriers, laying true global distribution systems. In addition, the ability to leverage the Internet as a tool for expanding the presence of these booking systems was promising. In response to these developments, the United States Department of Transportation (USDOT) increased regulation of the GDS industry.
• As the GDS industry continued to evolve in the 1990s, the availability of public interfaces to these systems greatly expanded, particularly with the rollout of the Internet and World Wide Web. 
• There are currently four major GDSs in operation, Amadeus, Galileo, Sabre and Worldspan, 

GDSs can be categorized in the following way: 

1) airline websites; 

2) GDS-based online, travel agencies such as Travelocity, Expedia travel and orbitz. 

3) opaque sites that require some type of bid/payment before knowing the actual travel schedule such as Priceline; 

4) specialty low-fare sites which are analogous to a tip-sheet for selected bargains; and 

5) Screen scraper sites which actually reads fare information from the screens of others sites .

1) GDS stands for Global Distribution System 

2) Global Distribution System is a Travel Agency Network that enables interconnectedness between Airline Computer Reservation Systems and travel agency terminals. 

3) It’s distinct from a Computer Reservation System which is a reservation system used by Airlines. 

4) The Global Distribution System (GDS) is used by travel agents to make reservation on various airline’s reservations systems. 

5) A Global Distribution System (GDS) differs from an airline CRS in one critical aspect, a GDS holds no inventory of its own. The inventory is held in various airline reservation systems. 

6) The GDS system has links to all major airline CRS. 

7) When a travel agency terminal requests a reservation on the service of a particular airline the GDS system routes the request to the appropriate airline Computer Reservation System. 

8) This enables a travel agent with a connection to a single GDS to book flights and associated services on virtually all the airlines in the world. 

9) The major GDS systems are Amadeus, Sabre, Galileo & Worldspan.

Homologous: Organs or structures that have the same origin and basic anatomical structure but perform different functions. 

Analogous organs : Structures that are different in their basic anatomical structure and origin but appear but similar and perform similar functions.

An environmental movement can be defined as a social or political movement, for the conservation of the environment or the improvement of the state of the environment. 

Hence, we can say that the Baliyapal movement is the right answer which opposed missile base establishment, which affects our soil fertility.

Gene therapy : 

Gene therapy is the replacement of a defective mutant allele with a functional gene into an individual cell and tissues to treat genetic hereditary diseases. 

OR 

It is the insertion of normal functional genes into the individual or embryo with genetic defect to take over the function of and compensate for the non – functional gene.
