The female figures as an allegory of the nation:

• Artists found a way out to represent a country in the form of a person.
• Then nations were portrayed as female figures.
• The female figure was chosen to personify the nation did not stand for any particular woman in real life.
• It gave the abstract idea of the nation a concrete form.
• Thus, the female figure became an allegory of the nation.
• During the French Revolution artists used the formal allegory to portray idea such as Liberty, Justice and the Republic.

Nagar Nigam Ko Application - मोहल्ले की सफाई हेतु। 

सेवा में,
श्रीमान कार्यकारी अधिकारी,
नगर निगम ,आनंद विहार (नई दिल्ली )

विषय:- मोहल्ले की सफाई हेतु।

मान्यवर ,
              हम आनंद विहार निवासी आपका ध्यान हमारे नगर में बढ़ रहे गन्दगी के तरफ आकर्षित करना चाहते हैं। सड़कों के किनारे कूड़ों का ढेर जमा हो रहा है , लोगों का पेदल चलना मुश्किल हो गया है। लोग अपने घर के गन्दगी को सड़कों के किनारे फेंकने को मजबूर हो गए है।
नगर में कूड़ादान तो है लेकिन उसे फेंकने वाला कोई नही है। सभी कूड़ादान भर गया है , अब लोग अपनी घर के गन्दगी को सड़कों के किनारे फेंकते हैं। कोई भी नगर निगम का कर्मचारी इन कूड़ों को ले जाने नहीं आते ,सिर्फ कूड़ादान लगाकर भूल गए हैं।

आयदिन देश में गन्दगी की वजह से नई-नई बीमारियां निकलती रहती है , हमें डर है कहीं इन कूड़ों की वजह से हमारे नगर में भी कोई बीमारी ना फ़ैल जाये। ऐसा कुछ हो इससे पहले हम नगरवासी आपको सूचित करते हैं कि आप कृपया यहां के गन्दगी को जल्द से जल्द दूर करें। और हमारे नगर के लिए कर्मचारियों को नियुक्त करे जो कूड़ेदान की गन्दगी को ले जाये। इस महत्वपूर्ण कार्य के लिए हम नगरवासी सदैव आपके आभारी रहेंगे।

सधन्यवाद।

Being a teenager can be challenging at times because growing up has its own set of problems. These problems need to be tackled with patience and faith – two qualities that teenagers need to inculcate gradually. Opening up to the wonderful world around and thanking God for the little blessings make the difficult task of growing up a wonderful journey.

• It is located in the stems and roots on the lateral side.

• It increases the thickness of the plant.

• Vascular cambium and cork cambium are the two lateral meristems.

• These divide preclinically or radially and give rise to secondary permanent tissues.

In AOAB, ∠OAB + ∠ABO + ∠BOA = 180°
∠OAB + ∠OAB + 90° = 180° ⇒ 2∠OAB = 180°- 90°
[angles opposite to equal sides are equal] [angle sum property of a triangle] [from Eq. (i)]
⇒ ∠OAB = 90°/2 = 45° …(i)
In ΔACB, ∠ACB + ∠CBA + ∠CAB = 180°
∴ 45°+ 30°+ ∠CAB = 180°
⇒ ∠CAB = 180° – 75° = 105°
∠CAO+ ∠OAB = 105°
∠CAO + 45° = 105°
∠CAO = 105° – 45° = 60°

Advantages :

1}These are the main source of power generation.

2}These projects control the floods because water can be stored in them. These projects have converted many, 'rivers of sorrows' into 'rivers of boon'.

3}Thes projects are the main source of irrigation and also help in conserving soil.

Disadvantages:

1}Dams also fragment rivers making it difficult for aquatic fauna to migrate for spawning, i.e , to produce eggs.

2}It resulted in displacement of local communities.

3}The multipurpose projects induced earthquake, caused waterborne diseases......

2. Quantum numbers may be defined as a set of 4 numbers with the help of which we can get complete information about all the electrons in an atom ,ie. location ,energy ,the type of Orbital occupied, space and orientation of that orbital.

1. 

postulates of Bohr's model of an atom are:

1. In an atom, the electrons revolve around the nucleus in certain definite circular paths called orbits, or shells.

2. Each shell or orbit corresponds to a definite energy. Therefore, these circular orbits are also known as energy levels or energy shells.

3. The orbits or energy levels are characterized by an integer not, where, n can have values 1, 2, 3, 4……. The integer not (= 1, 2, 3…) is called the quantum number of respective orbit. The orbits are numbered as 1, 2, 3, 4………… etc., starting from the nucleus side. Thus, the orbit for which n=1 is the lowest energy level.

The orbits corresponding to n = 1,2,3,4…..etc., are also designated as K,L,M,N……….etc., shells. When the electron is in the lowest energy level, it is said to be in the ground state.

Since, electronics can be present only in these orbits, hence, these electrons can only have energies corresponding to these energy levels, i.e., electrons in an atom can have only certain permissible energies .

4. The electrons present in an atom can move from a lower energy level (Elower) to a level of higher energy (Ehigher) by absorbing the appropriate energy. Similarly, an electron can jump from a higher energy level (Ehigher) to a lower energy level (Elower) by losing the appropriate energy.

The energy absorbed or lost is equal to the difference between the energies of the two energy levels, i.e.,

ΔE= E (higher) - E (lower)

Paradox of thrift. Since start of human civilisation it was considered a virtue to keep consumption level at the minimum but the lasting effects and chain reactions of keeping consumption in check were not realised. People were taught that thrift or savings are good because a penny saved today will bring increased income. In this connection, Keynes pointed out paradox of thrift and showed that as people become more thrifty, they end up saving less or same as before. If all the people of an economy increased the proportion of income which is saved (i.e., MPS), the value of savings in the economy will not increase, rather it will decline or remain unchanged. Let us understand this statement with the help of the figure (a).
In Fig (a), initial saving curve is SS and investment curve is II. Economy attains equilibrium (saving = investment) at E and equilibrium level of income is OY. Now, suppose the society decides to become thrifty and increases saving by, say, AE. As a result saving curve shifts upward to S₁S₁ intersecting investment curve II at E₁ Unplanned inventories will increase and firms will cut down production and employment and move to new equilibrium E₁ The Figure shows that in the end, planned saving has fallen from AY to E₁Y₁. Notice at new point of equilibrium E_1,, the investment level and also realised saving remain the same (E₁Y₁) but level of income has fallen from OY to OY_1. The decline in equilibrium level of income shows the paradox of thrift as the reverse process of multiplier has worked on reducing consumption expenditure. In fact, increased saving is virtually a withdrawal from circular flow of income.

There are four major sources of surface water. These are rivers, lakes, ponds, and tanks. In the country, there are about 10,360 rivers and their tributaries longer than 1.6 km each.
