1. Limited number of questions:The number of questions should be limited as far as possible. Normally fifteen to twenty questions are sufficient enough for making the required enquiry.

2. Simplicity:The language of the questions should be simple and easily understandable. It should be clear and not vague. It should not convey two meanings.

3. Logically arranged:The questions should be arranged logically. Ther should be a proper sequence of the questions.

4. Related to the points:Questions should be related to the point. They should not be irrelevant.

The Sumerians developed the first form of writing. As Sumerian towns grew into cities, the people needed a way to keep track of business transactions, ownership rights, and government records. Around 3300 BC the Sumerians began to use picture symbols marked into clay tablets to keep their records.

NaHCO3 + CH3COOH -----> CH3COONa + H2O + CO2 

Initial mass = 6.3 + 15 = 21.3 

Final mass = 18.0 + mass of CO2 

According to law of conservation of mass : 21.3 = 18.0 + mass of CO2 , 

Mass of CO2 = 3.3 g 

Ali was the fourth Caliph. He fought two wars against those who were representing the aristocracy of Mecca. As a result of these wars, the rifts among the Muslims depened. Later on his supporters and enemies got divided into two sects. These two sects were: Shias and Sunnis.

Mrs Dorling is an important character of Marga Minco’s short story The Address’. She is introduced to us as the mother of a fifteen-year old daughter. Like her daughter, Mrs Dorling has a ‘broad back’. When the narrator rings the bell, Mrs Dorling appears wearing the green knitted cardigan of the narrator’s mother. This shows how mercilessly she is using all ‘nice things’ of Mrs S.

Mrs Dorling’s behaviour towards Mrs S’ daughter is quite cold, unfriendly and inhuman. When the narrator introduces herself as the daughter of Mrs S, Mrs Dorling shows no sign of affection. Her remarks are very shocking and uncharitable. She utters : “Have you come back ?” She is not at all pleased to receive the daughter of Mrs S. She doesn’t feel “convenient”. She very coldly asks her to come “another time”.

Mrs Dorling lacks human qualities of head and heart. She is selfish. She is rude and ill mannered. She also lacks good sense and decency. She only knows how to exploit people and situations to her own advantage. She exploits Mrs S’s fear for war. She walks away with all her ‘nice things’ to 46, Marconi Street. She makes no effort to return them when the narrator visits her.

sin 100° + cos 100°

= sin100° + cos(90°+10°)
[cos 10° becomes sin 10°]

= sin100° + sin 10°

by the formula,

sin C + sin D = 2cos sin

= 2cos sin

= 2cos  sin 

= 2cos55° + sin45°

= 2cos55° + 1/√2

=√2.√2 cos55° .1/√2

= √2cos55°

A n s w e r : Maximum value is 1/2 and minimum value is -1/2.

EXPLANATION:

sin cos x = 1/2(2 sin x cos x)

= sin 2x/2

Hence, the Maximum value is 1/2 and minimum value is -1/2.

The aim of all scientific methods is the same, that is, to analyze the observation made at the beginning but there are various steps adopted as per the requirement of any given observation. However, there is a generally accepted sequence of steps of scientific methods.

1. Observation and formulation of a question: This is the first step of a scientific method. In order to start one, an observation has to be made into any observable aspect or phenomena of the universe and a question needs to be asked pertaining to that aspect. For example, you can ask, “Why is the sky black at night? or “Why is air invisible?”

1. Data Collection and Hypothesis: The next step involved in the scientific method is to collect all related data and formulate a hypothesis based on the observation. The hypothesis could be the cause of the phenomena, its effect, or its relation to any other phenomena.

1. Testing the hypothesis: After the hypothesis is made, it needs to be tested scientifically. Scientists do this by conducting experiments. The aim of these experiments is to determine whether the hypothesis agrees with or contradicts the observations made in the real world. The confidence in the hypothesis increases or decreases based on the result of the experiments.

1. Analysis and Conclusion: This step involves the use of proper mathematical and other scientific procedures to determine the results of the experiment. Based on the analysis, the future course of action can be determined. If the data found in the analysis is consistent with the hypothesis, it is accepted. If not, then it is rejected or modified and analyzed again.

A large number of tourists from around the world came to see the famous rock-cut tomb of Tut. They came down some 26 feet underground to pay their respect. They watched at the murals on the walls.
