The concept of Standard Deviation was introduced by Karl Pearson in 1893.

The middle value in a distribution refer to a) mean b) mode c) median d) geometric mean

Ans c) median

Generally, the scope of a research paper is followed by its limitations.

d - Methodology

Mean cannot be determined by graphical method.

Mean is the sum of the values of a subject divided by number of values.

As it is a single value and cannot be compared and represented in different values the determination of mean by the graphical method is not possible.

Mean is a perfect method for the determination of the central tendency of a value.

There are four frequently used measures of variability: the range, interquartile range, variance, and standard deviation.

When a capacitor is charged by a battery, work is done by the charging battery at the expense of its chemical energy. This work is stored in the capacitor in the form of electrostatic potential energy.

Consider a capacitor of capacitance C. Initial charge on capacitor is zero. Initial potential difference between capacitor plates = zero. Let a charge Q be given to it in small steps. When charge is given to capacitor, the potential difference between its plates increases. Let at any instant when charge on capacitor be q, the potential difference between its plates V=q/C

Now work done in giving an additional infinitesimal charge dq to capacitor

dW = V dq = q/C dq

The total work done in giving charge from 0 to Q will be equal to the sum of all such infinitesimal works, which may be obtained by integration. Therefore total work

Relation between Sufi Saints and State :

(i)    Major characteristic of the Chishti community was its simple and disciplined life. They emphasised to remain away from the mundane authority. But it did not mean to keep aloof from the political power. The Chishtis accepted all the donations made by the royal rulers. However they themselves never demanded such gifts or donations. The Sultans gave khanqahs land in donation. Many trusts were set up regarding grants, gifts and donations.

(ii)    The Chishtis accepted donation both in cash and kind. But they never accumulated donations. They spent them on immediate requirements like food, clothes, living quarters and ritual necessities. It enhanced the moral authority of the Shaikhs who attracted people from all walks of life. They became very popular as they possessed piety, scholarship, miraculous powers and royal patronage. That is why, all the rulers tried to secure their support.

(iii)    The Sultans knew that most of their subjects did not follow Islam. So when the Turks set up the Delhi Sultanate, they rejected the wish of the ulama to impose Shariat as state law. They expected opposition from their subjects as majority of them were non-Muslims. They depended on the sufis who derived their authority directly from God. They did not depend on jurists to interpret the Shariat.

(iv) There are many examples of conflict between the Sultans and the sufis. Both wanted to assert their authority. Both emphasised the prostration and kissing of the feet. Because of the moral authority of the Chishtis, the kings often wanted their tombs to be in the vicinity of Rufi shrines. On the other hand, the sufi Shaikhs were also addressed with high-sounding titles. For example, the disciples of Nizamuddin Auliya.

Charley knew that there were only two levels at Grand Station. In his fantasy he visited the Third Level as well. There he felt a strange mystery of 1894. Therefore, he consulted a psychiatrist. The psychiatrist thought that Charley had been day-dreaming. Side by side he revealed that the third level was still there. In reality Charley got upset with his dull life. It made him rush back from the third level.

The poet was coming from her parent's home in Cochin and she was driving to airport along with her mother.

Definition

Prokaryotic ribosomes refer to free ribosomes in prokaryotes while eukaryotic ribosomes refer to large ribosomes that facilitate translation in eukaryotes.

Found in

Prokaryotic ribosomes are found inside bacteria and archaea while eukaryotic ribosomes are found in animals, plants, fungi, and other unicellular eukaryotes with a nucleus.

Size

Prokaryotic ribosomes are small while eukaryotic ribosomes are larger. Further, the mass of a prokaryotic ribosome is 27000 kd while the mass of eukaryotic ribosomes is 42000 kd.

Sedimentation Coefficient

The sedimentation coefficient of prokaryotic ribosomes is 70S while the sedimentation coefficient of eukaryotic ribosomes is 80S.

Diameter

The diameter of a prokaryotic ribosome is ~200 Å while the diameter of a eukaryotic ribosome is ~250-300 Å

Subunits

Prokaryotic ribosomes are made up of 50S and 30S subunits while eukaryotic ribosomes are made up of 60S and 40S subunits.

National domestic income at factor cost = Private final consumption expenditure + Government final consumption expenditure − Net imports + (Gross domestic fixed capital formation + Closing stock − Opening stock) − Depreciation − Net indirect taxes

Net national disposable income = = NDP_FC − Net factor income to abroad + Net indirect taxes + Net current transfers from abroad

Example

National domestic income at factor cost = Private final consumption expenditure + Government final consumption expenditure − Net imports + (Gross domestic fixed capital formation + Closing stock − Opening stock) − Depreciation − Net indirect taxes

National income (NDP_FC) = = 300 + 100 − (−10) + (50 +25 − 25) − 20 − 80 = Rs 360 arab

Net national disposable income = = NDP_FC − Net factor income to abroad + Net indirect taxes + Net current transfers from ROW

Net national disposable income = 360 − 10 + 80 + (−5) = Rs 425 arab

Food Is Considered Adulterated If-

• A substance that degrades the quality of food or turns it hazardous is added to it.

• Cheaper or low-quality substances are used as a substitute for whole or a few ingredients.

• A constituent of food is a partly or wholly taken out, reducing the quality of food.

• It’s made presentable with harmful substances. Or its color is changed to make it look better.

• Anything that depreciates the quality of food is added to or abstracted from it.
