The difference:Potential Resources: Resources which are found in a region, but have not been utilised due to lack of capital or other reasons. For example, the western parts of India, particularly Rajasthan and Gujarat have enormous potential for the development of wind and solar energy, but so far, these have not been developed properly.
Stock Resources: Materials in the environment which have the potential to satisfy human needs but human beings do not have the appropriate technology to access these, are included among stock.
For example, water is a compound of two inflammable gases; hyd

John Keats is a poet of nature. He sees beauty in all the natural objects since a thing of beauty is a joy for ever. According to him every thing of nature is a source of beauty. In the poem we can see, the sun, the moon, the trees, daffodils, green forests, clear rills, masses of ferns, blooming musk-rose and lovely tales, etc. These beautiful sources provide pleasure and joy to the mankind.

Shehnai is an improved version of pungi as it has a better tonal quality than pungi. It is a natural hollow stem pipe  with seven holes on its body and is longer and broader than the pungi. 

(i) The poet wants us to keep quiet and give up endless activity to be able to introspect. He wants us to break free of the barriers of language and be united in a moment of eloquent silence.(ii) The poet wants us to give up our endless, incessant activities and be lost in eloquent, calm and peaceful silence break free of all barriers of language and communication.(iii) When the poet says ‘ not move our arms’, he wishes to convey that in the moment of eloquent peaceful silence we must all give up whatever we are doing. He means to say there must be absolutely no action, no activity and no com

i) Fe exists in the +3 oxidation state i.e, in d5 configuration.Since water is the weak ligand, therefore, there is no paired electron. Hence it is strongly paramagnetic and high spin.  Hybridization sp3d2.ii) 

Answer -: +ve x direction with frequency 1 Hz and wavelength A = 0.2 m
The sign between two terms in the argument of sine will define its direction.
Writing the given wave equation
y= 0.25 sin (10 Toe- 2t .. (i)
The minus () between (10mx) and (2rt) implies that the waves is travelling along the positive x-direction.
Now comparing eq (i) with standard wave equation
y=asin (kx-wt) ... (i)
we have

Language policy of India:
1. Our Constitution did not give the status of national language to any one language. Hindi was identified as the official language. But Hindi is the mother tongue of only about 40 per cent of the Indians. Therefore, there were many safeguards to protect other languages.
2. Besides Hindi, there are 21 other languages recognised as scheduled languages by the Constitution.
3. A candidate in an examination conducted for the national government positions may opt to take the examination in any of these languages. States too have their own official languages. Much of th

Inner radius of torroid core, rl
Outer radius, r2 = 0.26 m
Number of turns, N = 3500
Current in the wire, I = 11 A

(i) The magnetic field is zero outside the toroid because, there is no current flowing on
outside of the torroid.
(ii) Magnetic field inside the core of the toroid,

One of the reaction that takes place in producing steel from iron ore is the reduction of iron (II) oxide by carbon monoxide to give iron metal and CO2.

R = {(x + 1), (x + 5) : x = 0, 1, 2, 3, 4, 5}= {(a, b) : x = 0, 1, 2, 3, 4, 5}When x = 0, a = 0 + 1 = 1, b = 0 + 5 = 5x = 1, a = 1 + 1 = 2, b = 1 + 5 = 6x = 2, a = 2 + 1= 3, b = 2 + 5 = 7x = 3,  a = 3 + 1 = 4, b = 3 + 5 =8x = 4, a = 4 + 1 = 5, b = 4 + 5 = 9x = 5, a = 5 + 1 =6, b = 5 + 5 = 10Hence,  R in the roster form is {(1, 5), (2, 6), (3, 7), (4, 8), (5, 9), (6, 10)}Domain of R = {1, 2, 3, 4, 5, 6}Range of R = {5, 6, 7, 8, 9, 10}

∵   x4 - (y + z)4 = [x2]2 - [(y + z)2]2                       = [(x2) + (y + z)2] [(x2) - (y + z)2]                                                                                                      [Using a2 - b2 = (a+b)(a-b)]We can factorise [x2 - (y + z)2] further as       x2 - (y + z)2 = [(x) + (y + z)][(x) - (y + z)]                         = (x + y + z)(x - y - z)
∴      x4 - (y + z)4 = (x + y + z)(x - y - z)[x2 + (y + z)2]
     

Principle of potentiometer. The fall of potential along any length of the wire is directly proportional to that length. When a constant current flows through a wire of uniform cross-section and composition.V ∝ lComparison of emfs of two primary cells: The circuit diagram is shown in the figure.When the key K is closed, a constant current flows the potentiometer wire. By closing key K1, the cell E1 is included in the circuit. The jockey is adjusted till galvanometer shows no deflection. Suppose AJ1 = l1 is the balancing length for cell E1. ThenE1 = kl1where k is the potential gradient. Now the
