`O` is a point at the bottom of a rough plane inclined at an angle `alpha` to the horizontal. Coefficient of frictionbetween `AB` is`(Tanalpha)/(2)`and between `BO` is `(3Tanalpha)/(2)`. `B` is the mid–point of `AO`. A block is released from rest at A. Then identify which graphs are correct during motion of block from point `A` to `O` taking direction down the incline plane as positive `(sinalpha=1//5)` : A. B. C. D.

Answer» Correct Answer - C
For motion between `AB`
`ma=mg sin alpha-(tanalpha)/(2) mg cos alpha`
`a=(g sinalpha)/(2)` (downward)
For motion between `BO`
`ma=(3tan alpha)/(2) mg cos alpha-mg sin alpha`
`a=(gsinalpha)/(2)` (upward)
The velocity increases from zero to maximum value of `B` and then starts decreasing with same rate and finally becomes zero at `O`.

Compare reducing nature of Lithium and sodium with proper explanation.

Answer»
reducing power of sodium is lesser than lithium.....as going down the group makes less electronegative. It also has. higher hydration energy due to smaller size than sodium.

The greater reducing character of Li than Na is due to its greater hydration energy. Lithium being small in size has high ionization energy. On the other hand because of its small size it is easily hydrated with very high hydration enthalpy. This high hydration enthalpy compensates the high energy required to remove electron.

Let f(x) = ax2 + bx + c where a, b, c are real constants. If f(x + y) = f(x) + f(y) for all real x and y then

Answer»

\(f(x) = ax^2 + bx + c, \;a, b, c \in R\)

\(f(x+ y) = f(x) + f(y)\)

Take y = 0

\(f(x+ 0) = f(x) + f(0)\)

⇒ \(f(0) = f(x) - f(x) = 0\)

⇒ \(C = 0 \)    \((\because f(0) = C)\)

\(\therefore f(x) = ax^2 + bx \)

Take y = x

Then

\(f(x + x) = f(x) + f(x)\)

⇒ \( f(2x) = 2f(x)\)

⇒ \(f(2x) = 2f(x) = 2(ax^2 + bx)\)

⇒ \(a(2x)^2 + b(2x) = 2(ax^2 + bx)\)

⇒ \(4ax^2 + 2bx = 2ax^2 + 2bx\)

⇒ \(2ax^2 = 0\)

⇒ \(a= 0\)   (Because it is true for all x & y)

\(\therefore f(x) = bx \) which is a linear function

13.

If x = 4+2√2, then find (x-8+8/x).

Answer»

\(x = 4 + 2\sqrt 2\)

\(\frac 1x = \frac1{4 + 2\sqrt 2} = \frac {4 - 2\sqrt 2}{(4 + 2\sqrt 2) (4 - 2\sqrt 2)}\)

\(= \frac {4 - 2\sqrt 2}{16 - 8}\)

\(= \frac{4 - 2\sqrt 2}8\)

\(\therefore x - 8 + \frac 8x = 4 + 2\sqrt 2 - 8 + 4 - 2\sqrt2 = 0\)

14.

\(\frac{x^2 - 3x - 28}{x^2 - 49} = \frac 3{17} , \; x \ne \pm 7\)

Answer»

\(\frac{x^2 - 3x - 28}{x^2 - 49} = \frac 3{17} , \; x \ne \pm 7\)

⇒ \(17x^2 - 51x - 476 = 3x^2 - 147\)

⇒ \(14x^2 - 51x - 329 = 0\)

⇒ \(x = \frac{51 \pm \sqrt{2601 + 18424}}{28}\)

\(= \frac{51\pm \sqrt {21025}}{28}\)

\(= \frac{51\pm 145}{28}\)

\(= \frac {196}{28} \; or\; \frac{-94}{28}\)

\(= 7 \; or\; \frac{-47}{14}\)

\(\because x \ne 7\)

\(\therefore x = \frac{-47}{14}\)

A man is sitting inside a moving train and observes the stationary objects outside of the train. Then choose the single correct choice from the following statements`-`A. all stationary objects outside the train will move with same velocity in opposite direction of the train with respect to the man.B. stationary objects near the train will move with greater velocity & object far from train will move with lesser velocity with respect to the man.C. large objects like moon or mountains will move with same velocity as that of the trainD. all of these

Answer» Correct Answer - A
`vec(V)_(OM)=vec(V)_(O)-vec(V)_(M)`, `vec(V)_(O.M)=vec(V)_(O)-vec(V)_(Trai n)`
`V_(O.M)=` velocity of object with respect to man
`V_(O)=` velocity of object
`V_(M)=` velocity of man
Here velocity of object is zero.
So, `vec(V)_(O.M)=-vec(V)_(M)`

If the point P(k – 1, 2) is equidistant from the points A(3, k) and B(k, 5), find the values of k.

Answer»

Given that the point P(k –1, 2) is equidistant from the points A(3, k) and B(k, 5). 

Hence, distance of point P(k –1, 2) from point A(3, k) 

= distance of point P(k –1, 2) from point B(k, 5).

 = \(\sqrt{(3-k+1)^2+(k-2)^2}\)\(\sqrt{(k-k+1)^2 + 3^2}\) (By distance formula) 

⇒ (3 − k + 1)2 + (k − 2)2 = (k − k + 1)2 + 32 (By squaring both sides) 

⇒ (4 − k)2 + (k − 2)2 = 1 + 9 

⇒ 16 + k2 – 8k + k2 + 4 – 4k = 10 (∵(a − b)2 = a2 + b2 − 2ab) 

⇒ 2k2 – 12k + 10 = 0 

⇒ k2 – 6k + 5 = 0 

⇒ (k – 5) (k – 1) = 0 

⇒ k = 1 or k =5. 

Hence, the values of k are k = 1 and k = 5

Find the directional cosines of vector `(5hati+2hatj+6hatk)`. Also write the value of sum of squares of directional cosines of this vector.

Answer» Correct Answer - `(5)/(sqrt(65)), (2)/(sqrt(65)), (6)/(sqrt(65)); 1`
Let `alpha, beta & gamma` are the angles of vector `(5hati+2hatj+6hatk)` from x, y and z-axis respectively.
then `cos alpha = (A_x)/(A) = (5)/(|5hati+2hatj+6hatk|)= (5)/(sqrt(65))`
`cos beta =(A_y)/(A) = (2)/(|5hati+2hatj +6hatk|) = (2)/(sqrt(65))`
`cos gamma = (A_z)/(A) = (6)/(|5hati+ 2hatj+6hatk|) = (6)/(sqrt(65))`
The sum of squares of directional cosines of this vector
`cos ^(2) alpha + cos ^(2) beta + cos^(2) gamma = (5^(2) + 2^(2) + 6^(2))/(65) = (65)/(65) = 1`

उत्तराखण्ड राज्य के भूस्खलन सुभेद्य क्षेत्रों का वर्णन कीजिए तथा इसकी क्षति के न्यूनीकरण की युक्तियाँ बताइए।

Answer»

उत्तराखण्ड के भूस्खलन सुभेद्य क्षेत्र

उत्तराखण्ड राज्य का भू-स्खलन प्रभावशाली की दृष्टि से विश्व में चौथा स्थान है। यहाँ लगभग 1200 से अधिक गाँवों को भू-स्खलन सुभेद्य क्षेत्र में सम्मिलित किया गया है। हैदराबाद स्थित सुदूर संवेदन संस्थान की रिपोर्ट के अनुसार इनमें से अधिकांश गाँव ऋषिकेश-बद्रीनाथ-गंगोत्री-केदारनाथ मार्ग पर स्थिति हैं। एन०आर०एस० के लैण्ड हेजार्ड जोनेशन मानचित्र के आधार पर अलकनन्दा घाटी में 137, गंगा-अलकनन्दा घाटी में 24, गंगा-चन्द्रप्रभा घाटी में 25, गंगा घाटी में 21 तथा बेतसुथी नदी के निकट 23 गाँव संवेदनशील हैं। रुद्रप्रयाग-ऊखीमठ-केदारनाथ क्षेत्र के 60 तथा पिथौरागढ़-मालपा मार्ग के 13 गाँव अति संवेदनशील बताए गए हैं। राज्य के आपदा प्रबन्धन एवं न्यूनीकरण केन्द्र के अनुसार भी ऋषिकेश-बद्रीनाथ मार्ग पर लगभग 600, रुद्रप्रयाग-ऊखीमठ-केदारनाथ मार्ग पर 200, पिथौरागढ़-मालपा मार्ग पर 150 तथा उत्तरकाशी-गंगोत्री मार्ग पर 275 गाँव भू-स्खलन सुभेद्य क्षेत्र में सम्मिलित हैं।
न्यूनीकरण की युक्तियाँ

भूस्खलन के न्यूनीकरण हेतु निम्नलिखित युक्तियाँ महत्त्वपूर्ण सिद्ध हो सकती हैं।

1. नियोजित भूमि उपयोग–नियोजित भूमि उपयोग भू-स्खलन न्यूनीकरण की महत्त्वपूर्ण युक्ति है। इसके अन्तर्गत विभिन्न कार्यों के लिए उपयुक्त भूमि का चुनाव सबसे अधिक महत्त्वपूर्ण पक्ष है। यदि मकानों का निर्माण सुरक्षित स्थानों पर किया जाए तथा वनस्पति के लिए निर्धारित अनुपात में भूमि का उपयोग हो तो भू-स्खलन का जोखिम कम हो जाता है।

2. प्रतिधारण दीवारों का निर्माण-भू-स्खलन प्रभावित क्षेत्रों में सड़कों के किनारे तीव्र ढाल को रोकने के लिए विशेष प्रकार की प्रतिधारण दीवारों का निर्माण किया जाता है। रेल लाइनों के लिए बनाई गई सुरंग तथा मार्ग के किनारे काफी दूर तक इन दीवारों को बनाने से पर्वतीय ढाल से आने वाले मलबे को रोका जा सकता है।

3. स्थलीय जल प्रवाह को नियन्त्रित करना-वर्षा तथा अन्य स्रोतों से बहने वाले जल के निकास की उचित व्यवस्था करने से जल तत्त्व चट्टानों पर अपना दबाव नहीं बनाता है। इसीलिए आधार चट्टानें सुरक्षित रहती हैं, जिससे भू-स्खलन की सम्भावनाओं में कमी आती है।

4. इन्जीनियरी संरचना–कुशल अभियन्ताओं द्वारा निर्धारित मानकों के आधार पर भवनों की संरचनाएँ अधिक टिकाऊ होती हैं। अतः भू-स्खलन सम्भावित क्षेत्रों में कुशल इंजीनियरों के मार्गदर्शन में ही भवनों का निर्माण किया जाना उपयुक्त है।

5. वनस्पति आवरण-भू-स्खलन को नियन्त्रित एवं न्यूनतम करने में वनस्पति आवरण सबसे सरल और सस्ता उपाय है। इसके द्वारा चट्टानों को सुरक्षा कवच प्राप्त होता है तथा चट्टानें जल तत्त्व के प्रभाव से मुक्त रहकर भू-स्खलन से प्रेरित नहीं होती हैं।
