CBSE Notes for Class 8 Computer in Action – Advanced Features of Access 2013

In the previous chapter, we learnt that Access is a RDBMS software. Tables, Forms, Queries and Reports are the important objects that can be created in an Access database. In real life scenarios, hundreds of records are stored in the database tables. Access objects such as Queries, Forms and Reports provide a convenient and easy way to enter, search, analyse and display the large amounts of data stored in the database tables. Queries let us quickly extract data from one or more tables based on the given conditions. Forms and Reports let us enter or display data in a user friendly manner. Let us learn more about these objects.

QUERY
A query is used to retrieve selective data based on specific criteria from one or more tables. For example, you may design a query to display names of all students who have secured more than 90 percent or a query to find out details of customers who made a purchase in the past one month. Let us learn to create simple queries in Access.
Creating a Query
Just like tables, there is a Query Design view in which queries are created and a Query Datasheet view in which results of the query are displayed. Let us create a query based on table Student to filter the details of students whose percentage is more than 90.
To create a Query, follow the given steps.
Step 1: Click on the Create tab (Fig. 3.1).
Step 2: Click on the Query Design option in the Queries group. The Show Table dialog box appears (Fig. 3.2).cbse-notes-for-class-8-computer-in-action-advanced-features-of-access-2013-1

Step 3: Choose the table on which you want to base your query and click on the Add button. After adding the table, click on the Close button to close the Show Table dialog box. The selected table appears in a small window in the upper section of the Query Design View. The lower section of the Query Design View displays the Design Grid (Fig. 3.3). In this example, click and add the Doctor table.
Step 4: Add the fields to be used in the query in the Design Grid by following any one of the following.

  • Double-click on the field name in the small table window in the upper section of the Query Design View.
    OR
  • Drag and drop fields from the small table window in the upper section to the Field column in the Design Grid.
    In this example, add the D_Id, Name, Hospital, Fee and Specialisation fields to the Design Grid.

cbse-notes-for-class-8-computer-in-action-advanced-features-of-access-2013-2

Step 5: Type the search condition in the Criteria row of the field on the basis of which you want to choose or filter the records (Fig. 3.4).
In this example, type the condition >600 in the Criteria row of the Fee field.          .
Step 6: Clear the Show checkbox for fields that should not appear in the Query Result.
Step 7: If you want the Query results to be sorted, then select Ascending or Descending order from the Sort box under that field. In this example, select Ascending order in the Sort box under the Fee field.cbse-notes-for-class-8-computer-in-action-advanced-features-of-access-2013-3
Step 8: Click on the Save option in the Quick Access Toolbar or the Save option on the File tab to save the Query. You will notice that the Query object gets added to the Navigation Pane (Fig. 3.5).
Step 9: Click on the Run option in the Results group on the Design tab to execute the query. The query results appear in the Datasheet View, which looks like a table. You will notice that the query displays the details of all doctors with fee more than ?600 arranged in ascending order of the Fee field.cbse-notes-for-class-8-computer-in-action-advanced-features-of-access-2013-4

Creating a Query with Multiple Conditions
Let us learn to create queries with more than one condition.

  • Specifying the condition in the Criteria row for more than one field will result in a query that will select only those records that meet all the conditions.
    Consider the following queries based on the table Doctor (Fig. 3.1).

Example 1:
The following query shows the records for which the Fee<600 and the Hospital is Heal Well Hospital.cbse-notes-for-class-8-computer-in-action-advanced-features-of-access-2013-5

Example 2:
The following query shows the records for which the Fee>=600 and the Hospital is Heal Well Hospital and the Specialisation is Nephrologist.cbse-notes-for-class-8-computer-in-action-advanced-features-of-access-2013-6

  • Specifying the first condition in the Criteria row and other conditions in the Or row and the rows beneath it results in a query that meets one or more of the specified conditions.

Example 1:
The following query shows the records for which the Fee<600 or the Hospital is Heal Well Hospital.cbse-notes-for-class-8-computer-in-action-advanced-features-of-access-2013-7

Example 2:
The following query shows the records for which the Fee>=600 or the Hospital is Heal Well Hospital or the Specialisation is Nephrologist.cbse-notes-for-class-8-computer-in-action-advanced-features-of-access-2013-8

Unseen Passage for Class 8 Literary CBSE With Answers

A literary passage consists of extracts from works of great writers and can be in the form of novels, short stories and poetry.

Unseen Passage Solve Example With Answers for Class 8 Literary CBSE

When I was a girl of about twelve, I used to stay in a village in north Karnataka with my grandparents. Those days, the transport system was not very good, so we used to get the morning paper only in the afternoon. The weekly magazine used to come one day late. All of us would wait eagerly for the bus, which used to come with the papers, weekly magazines and the post.

At that time, Triveni was a very popular writer in the Kannada language. She was a wonderful writer. Her style was easy to read and very convincing. Her stories usually dealt with complex psychological problems in the lives of ordinary people and were always very interesting. Unfortunately for Kannada literature, she died very young. Even now, after forty years, people continue to appreciate her novels.

One of her novels, called Kashi Yatre, was appearing as a serial in the Kannada weekly Karmaveera then. It is the story of an old lady and her ardent desire to go to Kashi or Varanasi. Most Hindus believe that going to Kashi and worshipping Lord Vishweshwara is the ultimate punya. This old lady also believed in this, and savouring it as much as possible. Her struggle to go there was described in that novel. In the story, there was also a young orphan girl who falls in love but there was no money for the wedding. In the end, the old lady gives away all her savings without going to Kashi. She says, ‘The happiness of this orphan girl is more important than worshipping Lord Vishweshwara at Kashi.’

My grandmother, Krishtakka, never went to school so she could not read. Every Wednesday, the magazine would come and I would read the next episode of this story to her. During that time, she would forget all her work and listen with the greatest concentration. Later, she could repeat the entire text by heart. My grandmother too never went to Kashi, and she identified herself with the novel’s protagonist. So more than anybody else, she was the one most interested in knowing what happened next in the story and used to insist that I read the serial out to her.

Question 1.
Why was the morning newspaper delayed in the narrator’s village?
Answer:
The transport system in the area where the narrator used to stay was not very good.
Hence, the morning paper would arrive only by afternoon.

Question 2.
What is special about Triveni’s stories?
Answer:
Triveni was a wonderful writer. Her stories were special because they usually dealt with complex psychological problems in the lives of ordinary people and were always very interesting.

Question 3.
Why did the Grandmother depend on the narrator to know the story?
Answer:
Grandmother never went to school, and hence, she could not read. Every Wednesday when the magazine would come, the narrator, her granddaughter, would read the next episode of the story to her.

Question 4.
Why is it important to go to Kashi in Hinduism?
Answer:
Most Hindus believe that going to Kashi and worshipping Lord Vishweshwara is the ultimate punya. Hence, it is regarded as important to go to Kashi in Hinduism.

Question 5.
Find words from the passage that are antonyms of the following:
a. unpopular
b. simple
Answer:
a. popular
b. complex

Literary Passage (Poem)

Last night I had the strangest dream
I’d ever dreamed before,
I dreamed the world had all agreed
To put an end to the war.
I dreamed I saw a mighty room
Filled with women and men,
And the paper they were signing said
They’d never fight again.
And when the paper was all signed
And a million copies made,
They all joined hands and bowed their heads
And grateful prayers were prayed.
And the people in the streets below
Were dancing ’round and ’round,
While swords and guns and uniforms
Were scattered on the ground.
Last night I had the strangest dream
I’d ever dreamed before,
I dreamed the world had all agreed
To put an end to the war.

Question 1. What did the poet dream?

CBSE Class 10 Science Practical Skills – Resistors in Series

BASIC BUILDING CONCEPTS
Resistance: The property of a conductor which resists or opposes the flow of current through it is called the resistance of the conductor. Its SI unit is ohm(Ω).
Current ∝ 1/Resistance
The resistance of a uniform conductor is

  1. directly proportional to the length of the conductor and
  2.  inversely proportional to the area of cross-section of the conductor.
    Therefore,          R∝ l/A  or R = ρ l/A

where p is the constant of proportionality, called the specific resistance or resistivity of the material of the conductor. It depends on the nature of the material of the conductor, i.e. it is constant for a particular material but different for different materials. The unit of resistivity is ohm-metre or Ω-m.

Series combination of resistors:
The arrangement in which various resistors are connected in such a way that they provide only one path to the flow of current is called the series combination of the resistors. The series combination of resistors Rv R2 and R3 is shown in the figure given below.
CBSE Class 10 Science Practical Skills – Resistors in Series 1

CHARACTERISTICS OF SERIES CIRCUIT

  1. The current flowing through all the resistors in series circuit is same.
  2. The total voltage across the combination is equal to the sum of the voltage drop across the individual resistor.
  3. Voltage across any resistor is directly proportional to the resistance of that resistor (as I is constant).
  4.  Equivalent resistance of the series circuit is equal to the sum of the individual resistances, i.e. Req = R3 + R2 + R3.
  5. The value of equivalent resistance is higher than the highest value of resistor used in the series circuit.

Uses of series circuit:
It is used when

  1. the resistance of the circuit is to be increased.
  2.  the current in the circuit is to be decreased.
  3. the less potential difference across a particular resistor is needed.

AIM
To determine the equivalent resistance of two resistors when connected in series.

MATERIALS REQUIRED
Two standard resistance coils, ammeter, voltmeter, one-way plug key, low resistance rheostat, connecting wires, cell or battery eliminator.

THEORY
Series combination of resistors: The end to end connection of two or more resistors are said to be in series combination if they provide only one path to the flow of current, i.e. same current would flow through each resistor.
The equivalent resistance of the series combination of two resistors is given by
Rs = R1 + R2

PROCEDURE

  1. Connect the circuit in the similar manner as shown in circuit diagram or apparatus arrangement with one of the unknown resistors.
  2.  Find the values of two given unknown resistors R1 and R2 by adopting the procedure of Experiment 5 and record the observations in observation table.
  3.  Using Ohm’s law, find the value of each resistance. Let it be R1 and R,2.
  4. Connect the two given resistors in series combination across the terminals of voltmeter as shown in figure above.
  5.  Put the plug in the key and take the readings of ammeter and voltmeter.
  6. Repeat step 5 three times by changing the position of the sliding contact of the rheostat.
  7. Tabulate the readings and find the ratio of V and I for the series combination. It will give the equivalent resistance of the combination.

PRECAUTIONS

  1. Remove the dust and other insulating particles from the ends of connecting wires by rubbing it with a sand paper.
  2. All the connections should be kept tight and properly connected as per circuit diagram.
  3. Take out the plug from the plug key in between the two observations.
  4. A low resistance rheostat should be used in the circuit to obtain a large variation in current.
  5. A thick copper connecting wire should be used in the circuit.
  6. The positive terminals of the ammeter and voltmeter must be connected to the positive terminal of the battery or battery eliminator.
  7. The voltmeter should be connected in parallel to the combination of resistors.
  8. Never connect the two terminals of the cell without any resistance.

SOURCE OF ERROR

  1. Reading error may be possible while observing the pointer of ammeter and voltmeter.
  2. Thick connecting wires may not be available at the time of performing the experiment.
  3. Area of cross-section of resistance may not be uniform across the length of wire.
  4. There may be the use of high resistance rheostat.
  5. Current may be allowed for a longer period of time.
  6. The terminal screws of the instrument may not be tightened properly.

Quantifiers Exercises for Class 6 CBSE With Answers Pdf

Quantifiers are words used in front of nouns to show number or amount without being specific.

Use of Some and Any
‘Some’ and ‘any’ are used to state the quantity, amount of something. When using ‘some’ or ‘any’, the exact number is not stated. Some and any are quantifiers.

Study the following tables:

Use some in positive (affirmative) sentences. Some is used for both countable and uncountable nouns.
Examples

  • I have some friends. (Friends is countable)
  • I’d like some water. (Water is uncountable)

ANY: Use any for countable and uncountable nouns in Interrogative sentences.
Examples

  • Have you got any cheese? (Cheese is uncountable)
  • Have you got any friends? (Friends is countable)

Negative sentences
Example:

  • He hasn’t got any cheese.
  • He hasn’t got any friends in Chicago.

Exception:
We use some in questions when offering or requesting something.
Example

  • Would you like some bread? (Offer)
  • Can I have some water, please? (Request)

The same rules are true for something and anything, someone and anyone, and somewhere and anywhere.

Use of Much and Many
The words much and many mean a lot of.
If a noun is in singular, we use much
Example:

  • Much money

If a noun is in plural, we use many
Example:

  • Many friends

In everyday English, we normally use much/many only in questions and negative clauses.
Example:

  • How much money have you got?
  • Sarla does not have many friends.

In positive clauses with so, as or too, we also use much/many.
Example:

  • Sarla has so many friends.
  • She has as many friends as Suman.
  • Rohit has too much sweets.

In all other positive clauses, however, we prefer expressions like a lot of / lots of.
Example:

  • Sarla has a lot of / lots of friends.
  • Rohit has a lot of / lots of money.

Use of Little, a little, the little, few, a few, the few:
Little, a little, the little denotes quantity and are used before uncountable nouns
Few, a few, the few denote number and used before plural nouns.
Little/Few:-Both ‘Little’ and ‘Few’ denote ‘Scarcity’ or ‘lack’. They are almost none or negative in meaning.
Example

  • There was little hope for the patient. (=there was almost no hope)
  • There are few takers of the new car. (= almost no takers)

A Little and A Few
‘A Little’ conveys the idea of small amount.
‘A Few’ conveys the idea of a small number.
Example

  • A little knowledge is a dangerous thing.
  • A few members were absent from the meeting.

The Little and The Few:
The Little:- It conveys the idea of all amount.
The Few:- It conveys the idea of all the members.
Example

  • The little money he had was spent on his wife’s illness.
  • The few spectators who came to see the match were disappointed with India’s batting.

Title: The Mysterious Stranger

It was a quiet day in the small town of Rockville until a mysterious stranger arrived. He was tall and thin, with a scar above his left eyebrow. No one knew where he came from or why he was there.

The stranger kept to himself, but people couldn’t help but notice him. He would often be seen walking around town, observing everything around him. Some people thought he was a spy, others thought he was a criminal on the run.

One day, a group of teenagers decided to follow the stranger and find out what he was up to. They followed him to an old abandoned building on the outskirts of town. They watched as he went inside and disappeared.

The teenagers decided to investigate and snuck into the building. As they explored the old rooms, they stumbled upon a hidden door. They cautiously opened it, only to find the stranger inside, sitting at a table.

He looked up at them and smiled. “I’ve been expecting you,” he said.

The teenagers were shocked. They had no idea how the stranger knew they were there. He explained that he had been watching them and knew they were curious about him.

The stranger then revealed that he was a scientist who had been working on a secret project. He needed their help to complete it. The teenagers were hesitant at first, but the stranger promised it would be worth it.

Over the next few weeks, the teenagers worked with the stranger to finish his project. They learned about science, technology, and teamwork. When they finally finished, the stranger revealed his creation: a machine that could transport people through time.

The teenagers were amazed. They had never seen anything like it before. The stranger then offered to take them on a trip through time. They eagerly accepted.

The stranger set the machine for the year 1875, and they were transported to a small western town. They met famous cowboys and even helped save a damsel in distress.

When they returned to the present day, the teenagers were changed. They had learned about science, history, and teamwork. And they had made a new friend in the mysterious stranger.

Question 1.
The poet in the poem ‘For Anne Gregory’ conveys that we should give importance to the inner beauty and not the physical appearance. Elaborate with reference to the poem.
Answer:
In the conversation that takes place between Anne Gregory and another speaker, the poet has tried to show that inner beauty is real beauty whereas physical appearance is changeable and hence, unimportant. The first speaker says to Anne that young men love her for her beautiful yellow hair and may never love her for what she really is. To this, Anne replies that her hair-colour can be changed into black, brown or carrot, meaning that external beauty is all superficial and men should not love her for that. Through Anne’s reply, the poet has made clear his preference for internal beauty over physical appearance.

Question 2.
How right or wrong is it to judge someone on the basis of his/her physical appearance?
Answer:
Physical appearances never give the true account of a person as it can be changed with the help of clothing, make-up and other such things.
Something which is not true and real should not be used to judge the person carrying it. A person must be judged on the basis of his behaviour that shows the true characteristics of his personality. This is explained by Anne in her reply to the first speaker that her beautiful hair-colour which attracts men is changeable, hence, men should not fall in love with her based on her-hair colour.

Question 3.
Why do you think the other speaker mentioned the old religious man and the text that proves that only God can love Anne for herself alone?
Answer:
The speaker mentioned the text found by an old religious man that proves that only God can love Anne for herself alone. It is so because the speaker wanted to tell Anne that her desire that men should not see her outer beauty is not going to be fulfilled. The speaker tells Anne that only God can be so great as to avoid external beauty and look beyond it. Man, on the other hand, falls for all things that appear pretty from outside and never bothers about what lies inside.

The sources of air pollution in our city are numerous, including vehicular emissions, industrial activities, and construction work. The government has taken some steps to address this issue, such as banning the

use of diesel generators and implementing stricter emission standards for vehicles. However, more needs to be done to improve the air quality in our city.

I urge the government to take more concrete steps to reduce air pollution, such as promoting the use of public transportation, investing in renewable energy sources, and imposing stricter regulations on polluting industries. It is the responsibility of everyone to protect our environment and our health, and I believe that by working together, we can make a difference.
