ANS:- SUBORDINATION OF INDIVIDUAL INTERST INTO GENERAL INTERST

There are always all kinds of interests in an organization. In order to have an organization function well, Henri Fayol indicated that personal interests are subordinate to the interests of the organization (ethics). The primary focus is on the organizational objectives and not on those of the individual. This applies to all levels of the entire organization, including the managers.

dil. alkaline KMnO₄.

Gammexane has the formula C₆H₆Cl₆.

Two geometrical isomers are possible for dicarboxylic acid. They are cis and transform. In the cis form, similar groups are present on the same side of the double bond whereas in transform, identical groups are present on different side of the double bond.

1. When propene is treated with HBr, both 2-bromopnopane and 1-bromopropane are formed as products. The major product is2- Bromo-propane. This is due to the rule known as Markonikos rule of addition. It states that when a hydrogen halide is added to an unsymmetrical alkene, the halogen atom will goes to the doubly bonded carbon containing lesser number of hydrogen atoms.

2. In Acetylene, the hybridisation of carbon is sp and hence 50% s-character is present.

CH₃ -CH₃ -OH: Alcohol

The name given by the student is wrong. The correct name of the compound is 3- Ethyl -2-methyl nonane.

(1) C_nH_2n 

(2) Diamond, graphite 

(3) C₂H₆ . It is an alkane. All others are alkenes.

∴ Vapour density of compound is  = 161

∴ Molecular weight = 2 x vapour density

 = 2 x 161 = 322 g

∴ Number oxygen atoms = \(\cfrac{322\times\frac{69.5}{100}}{16}\) = 13.986 

 = 14 Oxygen atom

Number of hydrogen atoms = \(\cfrac{322\times\frac{6.22}{100}}{1}\) = 20.02

 = 20 Hydrogen atoms

∴ Maximum number of water molecule can present = 10 H₂O

∴ remaining number of oxygen atoms = 4

Number of S atom = \(\frac{322\times9.97}{32\times100}\) = 1.003

 = 1 sulphur atom

Number of sodium atoms = \(\cfrac{322\times\frac{14.3}{100}}{23}\) 

 = 2.003 = 2 sodium atoms

Therefore,  the molecular formula will be 

Na₂SO₄.10H₂O

1. When we treat acetaldehyde with fehings solution,then the deep blue colur of fehlings solution disappears and brick red colour is formed due to the formation of copper oxide
i,e Cu₂O

2. When acetic acid is heated with phosphorus pentachloride, acetyl chloride is obtained.

(d) reversible and adiabatic 

(b) perfect gas 

 (d) \(\cfrac{p_1v_1-p_2v_2}{n-1}\)

(d) both (b) and (c) 

(a) accounts for all energy entering and leaving a control volume 

(e) adiabatic processes.

(b) difference of two specific heats 

(a) conditions do not change with time at any point 

(d) there be no viscous or coloumb friction in the system 

(e) change in internal energy is zero.

(a) isothermal 

(d) enthalpy does not change 

Heat rejected to the cooling water, Q = – 50 kJ/kg 

(–ve sign since heat is rejected) 

Work input, W = – 100 kJ/kg 

(–ve sign since work is supplied to the system) 

Using the relation, Q = (u₂ – u₁) + W 

– 50 = (u₂ – u₁) – 100 or 

u₂ – u₁ = – 50 + 100 = 50 kJ/kg 

Hence, gain in internal energy = 50 kJ/kg.

Internal energy at beginning of the expansion,

u₁ = 450 kJ/kg

Internal energy after expansion, 

u₂ = 220 kJ/kg 

Work done by the air during expansion, 

W = 120 kJ/kg 

Heat flow, Q : 

Using the relation, Q = (u₂ – u₁) + W 

∴ Q = (220 – 450) + 120 

= – 230 + 120 = – 110 kJ/kg 

Hence, heat rejected by air = 110 kJ/kg.

(d) temperature only

Correct option is (1) 1.99 x 10⁵ J/mol

\(E_T = \frac{N_AhC}{\lambda}\)

\(E_T = \frac{6.02 \times 10^{23}\times 6.62 \times 10^{-34}\times 3 \times 10^8}{600\times 10^4}\)

\(= \frac{119.56 \times 10^{-3}}{600\times 10^{-9}}\)

\(= 19.93 \times 10^4J/mol\)

or 1.99 x 10⁵ J/mol

Correct answer is 2

g(1 - 2h/R) = g(1 - d/R)

2h/R = d/R

αh = d

α = 2

(d) The area of cross section of the conductor

The drift velocity is known to be primarily depends on the applied voltage and the molecular structure of the wire and hence the material of the conductor. Slight temperature depends is also observed.

(c) Remains same

Null point will remain same as resistance of both sides will decrease in the same ratio.

While packing the hamper, Harris packed a strawberry jam on top of a tomato and squashed it. So, they had to pick out the tomato with a teaspoon which was a messy and time-consuming task.

(3) Statement-1 is True, Statement-2 is False

Children will answer this question on the basis of their understanding of the story.

The field or space around a charge particle where its force can be experienced by any other charged particle is called the electric field of former charge. The area around a magnet within which magnetic force is exerted, is called a magnetic field. It is produced by moving electric charges. Electric and magnetic field both are two parts of one unique phenomenon.

Bhagwat Singh ji is the master of the haveli, ‘Jeevan Niwas’. He is kind, generous and merciful. He treats the maids and their children with affection. He gives Pari, the oldest maid, the regard of a mother. He scolds Heeralal, the driver, for misbehaving with Lakshmi. When he sees he is repentent, he forgives him. He arranges good schooling for Sita who is a maid’s daughter. Hence he was a big man with a big heart.

भगवत सिंह जी जीवन-निवास हवेली के स्वामी हैं। वह दयालु, उदार तथा रहम दिल हैं। वह सेविकाओं और उनके बच्चों के साथ प्यार से बर्ताव करते हैं। वह सबसे पुरानी सेविका परी को माँ का सम्मान देते हैं। वह हीरालाल ड्राईवर को सख्ती से फटकारते हैं क्योंकि उसने लक्ष्मी के साथ बदतमीजी की। जब वह देखते हैं कि वह पछतावा कर रही है तो वह उसे क्षमा कर देते हैं। वह लक्ष्मी की पुत्री सीता के लिये अच्छी शिक्षा की व्यवस्था करते हैं। अत: वह एक बड़े हृदय वाले बड़े आदमी थे।

Sita was a servant’s daughter whose mother had left her when she was in the suckling state. But her wedding was a family celebration as it had the full support of the mistress. But the mistress had watched the festivities with a sad heart. She could not forget Sita’s mother, Lakshmi especially when she was somewhere in the city. The mistress wept quietly. She felt that the parents’ presence was essential on the wedding of their daughter.

सीता एक नौकर की लड़की थी जिसकी माँ उसे उस समय छोड़ कर चली गई जब वह माँ का दूध पीने की अवस्था में थी। परन्तु उसका विवाह हवेली के पर्व जैसा था क्योंकि उसे मालकिन का पूरा समर्थन था। परन्तु मालकिन ने इन खुशियों को दु:खी हृदय से देखा था। वह सीता की मां लक्ष्मी को नहीं भूल सकी और विशेषकर उस समय जबकि वह शहर में थी। वह महसूस कर रही थी कि माता-पिता की उपस्थिति उनकी बेटी के विवाह पर अति आवश्यक है।

1.The author finds telephone a nuisance because it is a pest and time-waster. And also it may create unnecessary suspense and anxiety.

2. Yes, to some extent I agree with it all. Any gadget should be used only when it is re quired.

3. Use of a telephone box is a horrible experience for the writer. Due to unventilated air, smoking and other things, it is suffocating.

4. People who want to use all type of gadgets should develop their interest in them.

5. They should look at both positive and negative aspects of any machinery.

The two types of animal feed are:-

1. Fodder
2. Forage

Functions of fodder feed:

• It keeps the animal in good health.
• It is palatable and easy for digestion.
• It provides fresh nutrients in their natural form.

Functions of forage feed:

• It helps in providing excellent,generally dilute sources of nutrients.
• It supplies particularly valuable fibre for rumen digestion.
• Being home grown and, in many cases, more sustainable and economic than other feeds.

(i) Roughage is largely fibre. 

(ii) Concentrates are rich in proteins and nutrients.

Correct answer is (c) Iron
