28562.	If equations ( 2 x-3 y=7 ) and (a+b) x-(4 a+b) y=(a+b-3) have no solution then a and b satisfy the equation.
Answer» Given system of equations is 2x - 3y = 7 (a + b)x - (4a + b)y = a + b -3 system has no solution if \(\frac{a_1}{a_2} = \frac{b_1}{b_2} \neq \frac{c_1}{c_2}\) \(\Rightarrow\) \(\frac{2}{a + b} = \frac{-3}{-(4a + b)}\) \(\neq \frac{7}{a + b -3}\) \(\Rightarrow\) \(\frac{2}{a + b} = \frac{3}{4a + b}\) \(\Rightarrow\) 2(4a + b) = 3(a + b) \(\Rightarrow\) 8a + 2b = 3a + 3b \(\Rightarrow\) 5a - b = 0 \(\Rightarrow\) b = 5a Also \(\frac{2}{a + b} \neq \frac{7}{a + b - 3}\) \(\Rightarrow\) 2a + 2b - 6 \(\neq\) 7a + 7b \(\Rightarrow\) 5a + 5b \(\neq\) -6 \(\Rightarrow\) b + 5b \(\neq\) -6 \(\Rightarrow\) 6b \(\neq\) -6 \(\Rightarrow\) b \(\neq\) -1 Hence, given system has no solution if a and b satisfies the equation b = 5a but b \(\neq\) -1.

28562.

If equations ( 2 x-3 y=7 ) and (a+b) x-(4 a+b) y=(a+b-3) have no solution then a and b satisfy the equation.

Answer»

Given system of equations is

2x - 3y = 7

(a + b)x - (4a + b)y = a + b -3

system has no solution if \(\frac{a_1}{a_2} = \frac{b_1}{b_2} \neq \frac{c_1}{c_2}\)

\(\Rightarrow\) \(\frac{2}{a + b} = \frac{-3}{-(4a + b)}\) \(\neq \frac{7}{a + b -3}\)

\(\Rightarrow\) \(\frac{2}{a + b} = \frac{3}{4a + b}\)

\(\Rightarrow\) 2(4a + b) = 3(a + b)

\(\Rightarrow\) 8a + 2b = 3a + 3b

\(\Rightarrow\) 5a - b = 0

\(\Rightarrow\) b = 5a

Also \(\frac{2}{a + b} \neq \frac{7}{a + b - 3}\)

\(\Rightarrow\) 2a + 2b - 6 \(\neq\) 7a + 7b

\(\Rightarrow\) 5a + 5b \(\neq\) -6

\(\Rightarrow\) b + 5b \(\neq\) -6

\(\Rightarrow\) 6b \(\neq\) -6

\(\Rightarrow\) b \(\neq\) -1

Hence, given system has no solution if a and b satisfies the equation b = 5a but b \(\neq\) -1.

28563.	Write a factual description in about 100 words on “Consuming fresh Food instead of Camed food”.
Answer» There are three main differences between fresh food and canned food: Fresh food has a great flavour and taste. Canned food, however, loses the flavour because there are some other chemical products added to the natural food before canning.

Write a factual description in about 100 words on “Consuming fresh Food instead of Camed food”.

Answer»

There are three main differences between fresh food and canned food:
Fresh food has a great flavour and taste. Canned food, however, loses the flavour because there are some other chemical products added to the natural food before canning.
Canned food loses some of the original fresh food nutrients when stored. It has to be tinned with many preservatives and chemicals that prolong the life and apparent freshness of the food. But these could become toxic if consumed too often.
Canned food is much more expensive than fresh food. Here the benefit of buying tinned food is that it is easier to find.

डिब्बा बंद खाद्य व ताजे खाद्य में तीन मुख्य अंतर हैं –
ताजे भोजन में अत्यधिक सुगंध व स्वाद होता है। डिब्बा बंद भोजन में इसकी बहुत सारी सुगंध व स्वाद नहीं प्राप्त होता है क्योंकि डिब्बे में बंद करने से पहले प्राकृतिक भोजन में और कई दूसरे रासायनिक उत्पाद मिलाये जाते हैं।
डिब्बाबंद खाद्य को जब संग्रहीत किया जाती है उस समय वे ताजे खाद्य के कुछ पोषक तत्वों को खो देते हैं। इन्हें कई संरक्षकों तथा रसायनों के साथ डिब्बा बंद किया जाता है जो इनके जीवन को बढ़ा देते हैं तथा खाद्य की स्पष्ट रूप से ताजगी बनाये रखते हैं। लेकिन यदि इनकी बहुत अधिक सेवन किया जाये तो ये जहर भी बने। जाते हैं।
डिब्बी बंद खाद्य ताजे खाद्य से कहीं अधिक महँगे होते हैं । यहाँ पर डिब्बा बंद खाद्य को खरीदने का फायदा यह है कि इनको पाना आसान है।

28569.	How is the ending of "The Third Level" by Jack Finney ironic?
Answer» The story is about the notion of "escape," and specifically a kind of escape from history. Charley, the narrator, is a typical guy—one of dozens of men who look the same in their straw hats and gabardine suits. The escape Charley longs for is not a vacation from the city, however: he longs to escape to the past, to a time before the world wars. The non-existent third level of Grand Central station offers just such an escape: it is a kind of portal to the past. The ending is ironic because it is the narrator Charley's "psychiatrist friend" Sam who makes it back to Galesburg, Illinois in 1893, not Charley himself. Charley confided in Sam about the third level, and Sam of course told Charley that he was experiencing a kind of "waking dream wish fulfillment." But Sam "got to wishing" that Charley had been right; like everyone, Sam, too, craves an escape from the twentieth century; he was able to find the third level (because, it is suggested, he wanted escape so badly) and buy train tickets to Galesburg. In the end, it is the psychiatrist, who ostensibly is trying to ground Charley in the present, who escapes into a past where even his profession does not yet exist.

28591.	How many grams of solid NaOH must be added to 100ml of buffer solution which is 0.1M each w.r.t acid HA and salt Na+A- to make the pH of the solution 5.5
Answer» 0.2 g NaOH Explanation: You know that the hydroxide anions delivered to the solution by the sodium hydroxide will react with the weak acid to produce the conjugate base in 1:1 mole ratios. HA(aq)+OH−(aq)→A−(aq)+H2O(l) The number of moles of weak acid and of conjugate base present in the buffer before the addition of the strong base is given by moles HA=moles A−=0.1 moles103 mL⋅100mL moles HA = moles A−=0.01 moles Now, if you take x to be the number of moles of sodium hydroxide added to the buffer, you can say that after the reaction is complete, the resulting solution will contain (0.01−x) moles HA The reaction will consume x moles of the weak acid. (0.01+x) moles A− The reaction will produce x moles of the conjugate base. As you know, the pH of a weak acid-conjugate base buffer can be calculated using the Henderson - Hasselbalch equation. pH=pKa+log([A−][HA]) Assuming that the volume of the buffer does not change upon the addition of the strong base, you can say that the volume of the solution after the strong base is added is equal to 100 mL. That said, the fact that the volume is the same for both the weak acid and the conjugate base allows you to treat the concentrations of the two chemical species and the number of moles interchangeably. You can thus say that after the strong base is added, the pH of the solution will be equal to pH=pKa+log[(0.01+x)moles(0.01−x)moles] Plug in your values to find 5.5=5+log(0.01+x0.01−x) This will be equivalent to log(0.01+x0.01−x)=0.5 To find the value of x, rewrite this as 10log(0.01+x0.01−x)=100.5 You will ned up with 0.01+x0.01−x=3.16 0.01+x=0.0316−3.16x So x=0.0316−0.011+3.16=0.00519 Since x represents the number of moles of sodium hydroxide added to the buffer, you can use the molar mass of the compound to convert this to grams. 0.0519moles NaOH⋅39.997 g1mole NaOH=0.2 g−−−−

How many grams of solid NaOH must be added to 100ml of buffer solution which is 0.1M each w.r.t acid HA and salt Na+A- to make the pH of the solution 5.5

Answer»

0.2 g NaOH

Explanation:

You know that the hydroxide anions delivered to the solution by the sodium hydroxide will react with the weak acid to produce the conjugate base in 1:1 mole ratios.

HA(aq)+OH−(aq)→A−(aq)+H2O(l)

The number of moles of weak acid and of conjugate base present in the buffer before the addition of the strong base is given by

moles HA=moles A−=0.1 moles103 mL⋅100mL
moles HA = moles A−=0.01 moles

Now, if you take x to be the number of moles of sodium hydroxide added to the buffer, you can say that after the reaction is complete, the resulting solution will contain

(0.01−x) moles HA
The reaction will consume x moles of the weak acid.
(0.01+x) moles A−
The reaction will produce x moles of the conjugate base.

As you know, the pH of a weak acid-conjugate base buffer can be calculated using the Henderson - Hasselbalch equation.

pH=pKa+log([A−][HA])

Assuming that the volume of the buffer does not change upon the addition of the strong base, you can say that the volume of the solution after the strong base is added is equal to 100 mL.

That said, the fact that the volume is the same for both the weak acid and the conjugate base allows you to treat the concentrations of the two chemical species and the number of moles interchangeably.

You can thus say that after the strong base is added, the pH of the solution will be equal to

pH=pKa+log[(0.01+x)moles(0.01−x)moles]

Plug in your values to find

5.5=5+log(0.01+x0.01−x)

This will be equivalent to

log(0.01+x0.01−x)=0.5

To find the value of x, rewrite this as

10log(0.01+x0.01−x)=100.5

You will ned up with

0.01+x0.01−x=3.16
0.01+x=0.0316−3.16x

So

x=0.0316−0.011+3.16=0.00519

Since x represents the number of moles of sodium hydroxide added to the buffer, you can use the molar mass of the compound to convert this to grams.

0.0519moles NaOH⋅39.997 g1mole NaOH=0.2 g−−−−

Answer» Correct Answer is: (b) L and E_Tonly As no external torque acts on the system, its angular momentum is conserved. Since there is no loss of energy due to friction, the total energy is conserved. However, the ring acquires some translational kinetic energy as it slides outwards, and hence rotational kinetic energy is not conserved.
