Trading centers are the towns and cities where buying and selling of items take place, which were produced elsewhere. Trading center may be rural and urban. Rural marketing centers cater to nearby settlements, these are semi urban centers of rudimentary type and act as local collecting and distributing centers. Personal and professional services are not well developed here, but they are important to cater to the basic demand of rural people. In rural areas periodic markets are also organized, these markets are held on specified days and move from place to place.

The material noun is a noun which can be measured or weighted but cannot be counted.
or
The material noun is a substance, an ingredient, or a material that we can touch and see and it is used to make other things as well.
or
Material nouns are names of material out of which, things are made.
To make it understandable for you, look at the examples below:
Examples: gold, water, iron, rice, etc. now these things cannot be counted but are measured. Also, we make jewelry out of gold and pots from iron (related to the second definition).

Manchester export to India declined after the First World War because the British industries and mills  were busy in fulfilling the needs of the army. Most of the products were manufactured for meeting the war needs.Hence, the supply to India became restricted and the home market in India got an opportunity to supply their products.

Prove the following identites

sec⁴x - sec²x = tan⁴x + tan²x

SOLUTION

LHS = sec⁴x - sec²x

= sec²x(sec²x - 1)

= (tan²x + 1)(tan²x) (∵ sec²x - tan²x = 1)

= tan⁴x + tan²x

=RHS

Hence proved.

The Third ‘R’ – Recycling

The last stage of the waste hierarchy is to recycle. To recycle something means that it will be transformed again into a raw material that can be shaped into a new item. However, there are very few materials on the earth that cannot be recycled.

One of the issues bothering communities that want to become more involved with a recycling effort is that while the relying collection and sorting process may be affordable to implement, there still has to be a facility to receive and transform the discarded waste into a raw material to produce new products. 

More progress is being made toward uniting recycling plants with industries that can process the waste material through agreements and incentive credits.

Loss is defined as having something or someone leave or be taken away from you, a feeling of grief when something is gone, or a decline in money. An example of loss is when your parent dies. An example of loss is when you are fired from your job. An example of loss is what you feel when your pet dies. A loss occurs when an item is sold for less than it cost. A loss is often expressed as a percentage of the cost price. This is called the percentage loss. Profit % = 100 × Profit/Cost Price. Percentage Loss: The loss percent can be calculated as; Loss % = 100 × Loss/Cost Price.

Velocity selector is an arrangement of cross electric and magnetic fields is a region which helps us to select from a beam, charged particles of the given velocity. 

When a beam of charged particles of different charge and masses pass, through a region of crossed electric and magnetic field B each particle experience a force due to electric and magnetic field.

Then,

such particles go undeviated and filter out of the region.

Crystallization is a technique used for the purification of substances. A separation technique to separate solids from a solution.

• Purification of seawater
• Separation of alum crystals from impure samples
• In the pharmaceutical industry, crystallization is used as a separation and purification process for the synthesis and isolation of co-crystals, pure active pharmaceutical ingredients (API), controlled release pulmonary drug delivery, and separation of chiral isomers.

The process of deriving large crystals of pure substances from their solutions is known as crystallisation. It is a physical change. Crystals of salt are obtained by the evaporation of sea water.

Mainly computer system consists of three parts, that are central processing unit (CPU), <a href="https://www.tutorialandexample.com/input-devices-of-computer/">Input Devices</a>, and <a href="https://www.tutorialandexample.com/output-devices-of-computer/">Output Devices</a>. The Central Processing Unit (CPU) is divided into two parts again: arithmetic logic unit (ALU) and the control unit (CU). The set of instruction is in the form of raw data.

A large amount of data is stored in the computer memory with the help of primary and secondary storage devices. The CPU is like the heart/brain of the computer. The user does not get the desired output, without the necessary option taken by the CPU.  The Central processing unit (CPU) is responsible for the processing of all the instructions which are given by the user to the computer system.

                                       Fig: Block Diagram of the computer.

The data is entered through input devices such as the keyboard, mouse, etc. This set of instruction is processed by the CPU after getting the input by the user, and then the computer system produces the output. The computer can show the output with the help of output devices to the user, such as  monitor, printer, etc.

Step 1: Start with a circle

<a href="https://rapidfireart.com/2015/12/07/how-to-draw-a-face-in-8-steps/#"></a>

Draw a large circle and make a horizontal line below it for the chin. Then sketch the jawline. Draw a vertical line down the center of the face and make sure both sides of the face are symmetrical.

Step 2: Draw guidelines on the face

<a href="https://rapidfireart.com/2015/12/07/how-to-draw-a-face-in-8-steps/#"></a>

There are 2 ways to do this step: Ruler or no ruler. I highly recommend using the ruler method for the first couple of faces you draw. Why? Because doing this step without it can throw your proportions off like crazy. Especially if you have trouble locating the ‘center’ of an object with your eyes. The no ruler method requires you to split multiple sections of the face in half and then in half again.

Ruler Method: Make a ruler beside your drawing that is the same height. The ruler should be marked so there are 8 equal spaces. Always start with the center line.
Draw faint lines through the face on the markings labelled CENTER LINE, 2, 3, A, and C. As you get used to this, you won’t need to draw the ruler on the side.

No Ruler Method: Without the ruler, I draw lines in this order: CENTER LINE, 2, 3, B, A, C (B is included because it’s easier to break the forehead section in half first, especially when you’re drawing freehand). This is the method I use to draw heads all the time.<a href="https://rapidfireart.com/2015/12/07/how-to-draw-a-face-in-8-steps/#"></a>

Super SIMPLE Method: If it’s still a little confusing, check out my <a href="https://rapidfireart.com/2017/10/24/how-to-draw-faces-for-beginners-easy/" rel="noopener noreferrer" target="_blank">simple method here</a>. It’s also paired with a video so you can see how I do it!

Step 3: Draw eyes in the right spot

<a href="https://rapidfireart.com/2015/12/07/how-to-draw-a-face-in-8-steps/#"></a>

On the face, mark the center line with 4 ticks spread equally apart. The eyes will sit roughly on this line. Don’t be afraid to move slightly above or below the line, since eyes are usually slanted.

Step 4: Draw a proportionate nose

<a href="https://rapidfireart.com/2015/12/07/how-to-draw-a-face-in-8-steps/#"></a>

Extend the 2 lines where the inner corners of each eye are located. These guidelines will determine the nose’s width. Now that we have a box, it’s time to draw the nose.

Start with a circle, resting it anywhere between line 1 and 2. You can give your male character a more chiseled appearance by drawing the nose using very angular shapes.

Step 5: Add the eyebrows

<a href="https://rapidfireart.com/2015/12/07/how-to-draw-a-face-in-8-steps/#"></a>

Extend the nose’s bridge past the eyelids to define the brow bone (this step is optional). These lines should be very light!
Using a 4B pencil, draw the eyebrows along the brow bone. Facial features that can accentuate masculinity are thick bushy eyebrows!

Step 6: Use a triangle shape to draw lips

<a href="https://rapidfireart.com/2015/12/07/how-to-draw-a-face-in-8-steps/#"></a>

Draw a vertical line down the center of each eye. This will mark the lips’ outer boundary. <a href="https://rapidfireart.com/2013/05/10/how-to-draw-lips/" rel="noopener noreferrer" target="_blank" title="How to Draw Lips in 10 Easy Steps">Click here for my lips tutorial.</a> If you’ve already read it, place your triangle in the small box under the nose to start. If you drew the nose well above line 2, extend the triangle so the tip touches the nose.

Step 7: Add the ears

<a href="https://rapidfireart.com/2015/12/07/how-to-draw-a-face-in-8-steps/#"></a>

The Center Line and Line 2 mark the general boundaries for each ear.

Step 8: Draw the hair

<a href="https://rapidfireart.com/2015/12/07/how-to-draw-a-face-in-8-steps/#"></a>
Draw the upper hairline somewhere in between line A and B. It’s up to you how large you want the forehead to be. To draw a receding hairline, go above line A. When you’re drawing a man’s face, bring in hair from the sides of the head to create a solid and visible looking hairline.

Production and consumption of steel is regarded as the index of a country’s development because of the following reasons: 

• The production and consumption of iron and steel reflects the level of industrialisation and economic development of a country. 
• All the other industries depend on it for their machinery. It provides raw material for making industrial machinery, electrical machinery, defence equipments, bridges, dams, shops, houses, etc. 
• Vehicles carrying goods from one place to another are also made up of steel. It is because of these vehicles that our goods are transported from one place to another. 
• Steel is required to manufacture a variety of consumer goods, like bicycles, fans, furniture, tractors, etc. 
• It is the basic unit of economy. All buildings and infrastructures are constructed using iron and steel. 

Production and consumption of steel are often regarded as the index of a country's development as:

• The products of these enterprises are used as the raw material in different industries.
• For this reason it is called the feeder industry.
• Steel products are required for exports.
• Steel is used to create various machinery for ensuring country’s growth.

1. Device management
   In a computer system, there is a tremendous speed mismatch between the CPU and the I/O devices. The job of an operating system is to maintain a balance between the CPU and I/O devices. Apart from this, it has to maintain a balance between various I/O devices and has to keep the CPU busy in various processing.
2. Processor Management
   A process or a job is an application program in running state. Processor management is the important part of an OS, which enables the activities of planning, monitoring and performing a process. During execution, a process needs certain resources such as CPU time, memory space, files and I/O devices.

Anne Frank is the young writer of The Diary of a Young Girl. She emerges as a playful yet introspective teen forced to live under extraordinary and trying conditions. Over the course of The Diary, Anne seems to grow from an impudent and stubborn girl into an emotionally independent young woman.
Despite having a loving family and several friends, Anne is unable to share her thoughts with any of them. Instead, she turns to her diary for this purpose. She has a troubled relationship with her mother who she believes falls short of her ideal mother. She is close to her father. But, in her mind, even he fails to provide her with the emotional comfort she seeks. She has a rebellious spirit, desires to be treated as an adult and hopes to make a name for herself in the world.
Accounts of Jewish suffering anguish Anne to the point of remorse at her own good fortune. Nevertheless, she holds on to her ideals of honesty, hard work and self-improvement, and her trust that humans are essentially good.

Central Idea of The Ball Poem is - The poet watches a young boy playing with his ball. The next minute, his ball rolls away from him and fall into the water of the harbor. As the boy watches his ball disappear, he can also feel his childhood slip away from him. He feels himself growing up very fast as he learns that loss is a part of everyday life and that life goes on despite it. The sight of the sad little boy pains the poet, but he knows that growing up is an unavoidable process

PROM stands for Programmable Read Only Memory while EPROM stands for Erasable Programmable Read Only Memory, and EEPROM stands for Electrically Erasable Programmable Read-Only Memory.

PROM is a Read Only Memory (ROM) that can be modified only once by a user while EPROM is a programmable ROM that can be erased and reused. EEPROM, on the other hand, is a user-modifiable ROM that can be erased and reprogrammed repeatedly through a normal electrical voltage.

RAM: The full form of RAM is Random Access Memory. The information stored in this type of memory is lost when the power supply to the PC or laptop is switched off. 

ROM: The full form of ROM is a Read-Only Memory. It is a permanent type of memory. Its content are not lost when the power supply is switched off. The computer manufacturer decides the information of ROM, and it is permanently stored at the time of manufacturing, which cannot be overwritten by the user.

PROM: The full form of PROM is Programmable Read-Only memory. This type of ROM is written or programmed using a particular device.

EPROM: The full form of EPROM is Erasable Programmable Read-only memory. It stores instructions, but you can erase only by exposing the memory to ultraviolet light.

EEPROM stands for electrically Erasable Programmable Read-Only Memory. It stores and deletes instructions on a special circuit.

Monitor is an output device that receives processed information from the computer's CPU and displays it for the user.

Monitor is a computer peripheral, which is an electronic screen. The display in electronic form is called a softcopy. Monitor is also called as a visual display unit.   The display is made up of a series of dots called pixels.

Different types of monitors are:

Cathode Ray Tube (CRT)

CRT was in used until 21st century, but now they are phased out. It contains a vacuum tube that displays images using multiple electron guns and a phosphorescent screen.

Liquid Crystal Display (LCD)

LCD using liquire crystals to display images and the screen used is a flat panel of display.

Light Emitting Diode (LED)

LED uses semiconductor light source, where light is emitted when electricity flows through it.

Plasma Display

In a plasma display, each pixel is illuminated by plasma (also called as charged gas). It is thinner than CRT and LCD.

As a rule, specialists name three types based on what is inside them.

These types are:

CRT – Cathode Ray Tube

LCD – Liquid Crystal Display

LED – Light Emitting Diodes
