What is the output of the following program fragment. Choose appropriate data-types of variables to match output.
i=7;j=8;k=9;
printf(“%d”,(i+10)%k/j);

Answers

Answer:

1

Explanation:

Given :

i=7;j=8;k=9;

printf(“%d”,(i+10)%k/j);

The printf function only displays the result

%d - is used for the display format

However, the actual calculation is in the expression: (i+10)%k/j

Given the variables :

i = 7 ;

j = 8 ;

k = 9 ;

(i + 10) = (7 + 10) = 17

(i + 10) % k = 17 % 9

% = remainder value after division

17 % 9 = (17 / 9) = 1 remainder 8

17 % 9 = 8

Hence,

(i + 10) % k = 8

(i + 10) % k / j

j = 8

8 / 8

= 1

Explanation:

The term hydrostatic is defined as the science of fluids with no motion. In this definition a fluid is a substance that flows continually when a shear stress is applied. A fluid can be liquids or gases.

A fluid at rest can experience shear stresses mainly caused by friction between fluid particles caused by fluid viscosity. Such fluids can not resist this type of stress hence they will move in respond to the shear stress applied.

Based on the calculations, the length of the box must be equal to 24 inches.

Given the following data:

Trade size A (larger) = 3 inches.Trade size B = 2 inches.

Article 314 of the National Electrical Code (NEC).

This article provides the standard requirement and dimensions for the installation and use of all electrical boxes and conduit bodies that are used as pull boxes, outlet, junction, etc.

Straight pull with two raceways.

Basically, electrical boxes that contain straight pulls are typically sized based on the largest single raceway which enters the box. Also, you should multiply the trade size of the largest raceway by eight (8) when calculating the minimum length of an electrical box containing straight pull in accordance with Article [314.28(A)(1)] of the National Electrical Code (NEC).

For the minimum length:

Give five examples of
monopolies and collusion among sellers and their effects on the market economy.

Answers

Answer:

to reduce the amount paid to suppliers. For example, a retailer with great buying power (Walmart, Amazon) can offer very small profit margins to suppliers as they have little alternative.Collusion between existing firms in an industry to exclude new firms from deals to prevent the market from becoming more competitive.Sticking to output quotas and higher prices.Collusive tendering. For example, ‘cover prices’ for competitive tendering in bidding for public construction contracts. This is when a rival firm agrees to set artificially high price to allow the firm of choice to win with a relatively high contract offer.Types of collusionFormal collusion – when firms make formal agreement to stick to high prices. This can involve the creation of a cartel. The most famous cartel is OPEC – an organisation concerned with setting prices for oil.Tacit collusion – where firms make informal agreements or collude without actually speaking to their rivals. This may be to avoid detection by government regulatorsPrice leadership. It is possible firms may try to unofficially collude by following the prices set by a  market leader. This enables them to keep prices high, without ever meeting with rival firms. This kind of collusion is hard to prove whether it is unfair competition or just the natural operation of markets.Problems of collusionCollusion is seen as bad for consumers and economic welfare, and therefore collusion is mostly regulated by governments. Collusion can lead to:High prices for consumers. This leads to a decline in consumer surplus and allocative inefficiency (Price pushed up above marginal cost)New firms can be discouraged from entering the market by types of collusion which act as a barrier to entry.Easy profits from collusion can make firms lazy and avoid innovation and efforts to increase productivity.Industry gets the disadvantages of monopoly (higher price) but none of the advantages (e.g. economies of scale)Justification for collusionIn times of unprofitable business conditions, collusion may be a way to try and save the industry and prevent firms from going out of business, which wouldn’t be in the long-term consumer interest. Dairy suppliers tried to use this justification in 2002/03 after problems from foot and mouth disease led to a decline in farm incomes.Research and development.

How does the process of system engineering allow for the development of a well-integrated structure?







How does the integration of system engineering early in the design process provide benefits to the overall design?

Answers

Systems Engineering (SE) is the engineering discipline that focuses on integrating all the key elements of a system into one overall system and managing it throughout its lifecycle from cradle to grave. It’s focuses on the overall development process of a system that is based on established processes, documented needs and traceable communications or interaction among the customers, users, engineers, and other stakeholders. The overall goal of SE is to develop and design a system that meets a specific set of requirements (needs) in the guidelines established by the Program Manager (PM). A systems engineer in the DoD will develop, design, allocate, and manage user and system level requirements (see Requirements Development), lead the development of the system architecture, evaluate design tradeoffs, balance technical risk between systems, define and assess interfaces, provide oversight of verification and validation activities, as well as many other tasks throughout the course of a program. In short, SE is the technical discipline that glues all the pieces together to make the end product.
