(b) The Kyoto protocol is a protocol to the United Nations Framework convention on climate change aimed at fighting global warming. This protokol adopted on 11 December 1997 in Kyoto, Japan. Under the protocol 37 countries commit themselves to a reduction of four greenhouse gases and two groups of gases.

(b) infrared radiation passed through glass as easily as sunlight. 

(d) Ozone contributes to 3-7% of Greenhouse effect. The largest net source of tropospheric ozone is influx from the stratosphere. Large amounts of ozone are also produced in the troposphere by photochemical reactions, the amounts increasing with high levels of air pollution.

(a) Chlorofluorocarbons (CFCs) and their replacements (15%) are 1000 times more heat absorbent than carbon dioxide. They reach the atmosphere from refrigeration & air conditioning, aerosol sprays, and foam packaging industry

The Right option is:(c) 1 and 4 

(c) 1, 2 and 3 

(c) Methane and nitrous oxide are the two green house gases emitted from rice field. In rice field, the flooding a field cuts off the oxygen supply from atmosphere resulting anaerobic condition which emittes methane and nitrogen fertilizer which generally used in rice field for high production, emits nitrous oxide by the reaction with atmospheric oxygen.

Powder is used in carom board for decreasing friction.

The frictional force exerted by fluids is called drag.

1. The motion of balloon is uniform motion. It has neither acceleration nor retardation.

2.  u = 14m/s, a = -9.8, S = -98 m.

S = ut + 12 at²

98 = 14 t – 12 × 9.8 t²

4.9 t² – 14 t – 98 = 0

Solving this we get t = 6.123 sec

3. ν² = u² + 2as

ν²= (14)² + 2 x 9.8 x 98

   = 196 + 1920.8

ν² = 2116.8

ν² =√(2116.8) = 45.99 m/s.

Given:                             

3 married couples have bought 6 seats in the same row for a talent show.

Formula used:

n! = n × (n – 1) × (n – 2) ……………………….3 × 2 × 1

Calculation:

The guys all sit first, but they have to take up 3 spaces.

Assuming we're dealing with male-female married couples here

The men have 3! ways of sitting, as do the women

Total=

⇒ 3! × 3!

⇒ (3!)²

⇒ (6)²

⇒ 36

∴Different ways can they be seated if all men sit together to the right of all women is 36.

(c) Farmers being poor and illiterate do not use modern farming techniques

(c) higher among males than females

Given

Quantity of mixture = 40 litres

Water in mixture = 10%

Calculation

Quantity of Water in mixture = 10% 0f 40 = 4 litres

Quantity of Milk in mixture = 40 - 4 = 36 litres

There is 20% water in new mixture

∴ Ratio of water and milk is 20 : 80

⇒ 1 : 4

Let the quantity of water and milk in the new mixture be x and 4x

Water is added to make the new mixture, so the quantity of milk is constant throughout

⇒ 4x = 36

⇒ x = 9

So, Quantity of water in the new mixture is 9 litres

Quantity of water added = 9 - 4 = 5 litres

1. (d) the blue

2. (d) in a tea cup

3. (d) by its cove

4. (c) has a silver lining

5. (c) and a leg

6. (d) injury

7. (d) your thoughts

8. (d) the bold

9. (d) on the head

10. (a) blue moon

calculation:

1225 = 5 × 5 × 7 × 7

To make it a perfect cube it must be multiplied by 5 × 7 .

5 × 5 × 5 × 7 × 7 × 7 = 42875

∴ required answer is 35 

Calculation:

675 = (3 × 3 × 3) × (5 × 5)

if it is multiplied by 5 it become a perfect cube.

 (3 × 3 × 3) × (5 × 5 × 5) = 3375

Given:

(a + 3b) : (2a + 4b) = 3 : 5

Formula used:

if \(\frac{a}{b} = \;\frac{c}{d}\)

then, \(\;\;\frac{{a - b}}{{a + b}} = \;\frac{{c - d}}{{c + d}}\)

Calculation:

\(\frac{{\left( {a + 3b} \right)}}{{\left( {2a + 4b} \right)}} = \;\frac{3}{5}\)

⇒5 × (a + 3b) =  3 × (2a + 4b) 

⇒5a + 15b = 6a + 12b

⇒a = 3b

⇒\(\frac{a}{b} = \;\frac{3}{1}\)

⇒\(\frac{{a - b}}{{a + b}} = \;\frac{{3 - 1}}{{3 + 1}}\)

⇒\(\frac{{a - b}}{{a + b}} = \;\frac{2}{4} = \;\frac{1}{2}\)

⇒(a - b) : (a + b) = 1 : 2

Correct option is B) cut down on

No it is not. It is a guarantee concept not insurance.

Self Help groups (SHG) have helped borrowers to borrow money without collateral in the following ways: 

(i) Self help groups have organised rural poor more so women in collecting their money and in extending loans to its members. 

(ii) SHG charge less rate of interest as compared with any other forms of rural banking or even those charged by moneylenders. 

(iii) These groups gradually can seek loans for the bank so as to create employment opportunities for its members. 

(iv) Banks have been extending loans to these groups to meet their needs like buying fertilizers, seeds, raw materials etc. 

(v) These SHG have emerged as building blocks of the rural poor as it is the group as a whole which is responsible of the repayment of the loan. In case, of non repayment it is taken up in a serious manner by the group members. Thus, because of this, banks offer money to women organised in these groups without any collateral. Similarly, members of these groups can get loans when required which is repayable in small instalments.

The answer is : True.

The correct answer is General Bakht Khan.

• During the course of the Great Revolt of 1857, the leadership at Delhi was nominally in the hands of Bahadur Shah, but the real control was exercised by General Bakht Khan.

• The Bakht Khan took the responsibility and marched to Delhi to support the Mughal army. 
• When the Bahadur Shah became Emperor of India, he gave Bakht khan the title of Saheb-e-Alam Bahadur. Bakht Khan became the actual commander of the sepoy forces.
• The real commander in chief Mirza Zahiruudin due to lack of any military experience was just a nominal commander.
• Eventually, the leadership at Delhi was nominally in the hands of Bahadur Shah, but the real control was exercised by General Bakht Khan.
