where $ O $ denotes $ 2 \times 2 $ null matrix is f then surn of dights of th.plz help give perfect soln

Answer»

M = $\begin{bmatrix}a & -360 \\b & c \\\end{bmatrix}$

M²= $\begin{bmatrix} a & -360 \\ b & c \\ \end{bmatrix}$ $\begin{bmatrix} a & -360 \\ b & c \\ \end{bmatrix}$

= $\begin{bmatrix} a^2&-360 b \,\,\,-360(a+c)\\ b(a+c) &\,\, c^2 -360\,b\end{bmatrix}$

-360 (a+c) = 0 ⇒ a = -c

a² - 360 b = 0 ⇒ b = $\frac{a^2}{360}$

a,b,c are integer

so , for smallest positive value of b , we have

a = 1 or a = -1

∴ b = 1/360 is smallest positive value of b where o²is null matrix . only

needed condition is c = -a

Answer» Correct option is (1) 1 \(S_1 = 1\) \(S_2 = \frac{3S_1 + 4}{3 + 2s_1} = \frac{3 +4}{3 + 2} = \frac 75\simeq1.4\) \(S_3 = \frac {3S_2 + 4}{3 + 2S_2} = \cfrac{3\times \frac 75 + 4}{3 + 2\times \frac 75} = \cfrac{\frac{21 + 20}5}{\frac{15 + 14}5} = \frac{41}{29}\simeq1.413\) \(S_4 = \frac{3S_3 + 4}{3 + 2S_3} = \cfrac{3\times \frac{41}{25} + 4}{3+ 2 \times \frac{41}{25}} = \cfrac{\frac{123 + 116}{29}}{\frac{87 + 82}{29}} = \frac{239}{169} \simeq 1.414\) \(S_5 = \frac{3S_4 + 4}{3 + 2S_4} = \cfrac{3\times \frac{239}{165}+4}{3+2\times \frac{235}{169}}= \cfrac{\frac{717+676}{169}}{\frac{507 + 478}{169}} = \frac{1393}{985} \simeq1.414213\) \(\lim\limits_{n \to \infty} S_n = \sqrt 2\) \(\lim\limits_{n \to \infty} (2^{n/2} + (\frac \pi 4)^n)^\frac 1n\) \((\infty \; type)\) \(= Exp \left\{\lim\limits_{n\to \infty} \frac{log(2^{n/2} + (\frac\pi4)^n)}{n}\right\}\) \((\frac \infty \infty \; type)\) \(= Exp \left\{\lim\limits_{n\to \infty} \cfrac{2^{n/2}\frac{log2}2 + (\frac \pi4)^n log (\frac \pi4)}{2^{n/2} + \left(\frac \pi4\right)^n}\right\}\) \(= Exp\left\{ \lim\limits_{n\to \infty} \cfrac{\frac12 log2 + \left(\frac\pi4\right)^n log(\frac\pi 4)2^{-n/2}}{1+ (\frac \pi4)^n \,2^{-n/2}}\right\}\) \(= e^{\frac 12 log 2} = e^{log2^\frac12} = 2^\frac12 = \sqrt 2\) \(\therefore \frac{\lim\limits_{n\to \infty } S_n}{\lim\limits_{n\to \infty} \left(2^\frac n2 + (\frac \pi 4)^n\right)^\frac1n} = \frac{\sqrt 2}{\sqrt 2} = 1\)

2.

If $ S_{1}=1 $ and $ S_{n+1}=\frac{3 S_{n}+4}{3+2 S_{n}}, n \geq 1 $ Then $ \frac{\lim _{n \rightarrow \infty} S_{n}}{\lim _{n \rightarrow \infty}\left((2)^{n / 2}+\left(\frac{\pi}{4}\right)^{n}\right)^{\frac{1}{n}}} $ is (1) 1 (2) 2 (3) 4 (4) $ \frac{1}{2} $

Answer»

Correct option is (1) 1

$S_1 = 1$

$S_2 = \frac{3S_1 + 4}{3 + 2s_1} = \frac{3 +4}{3 + 2} = \frac 75\simeq1.4$

$S_3 = \frac {3S_2 + 4}{3 + 2S_2} = \cfrac{3\times \frac 75 + 4}{3 + 2\times \frac 75} = \cfrac{\frac{21 + 20}5}{\frac{15 + 14}5} = \frac{41}{29}\simeq1.413$

$S_4 = \frac{3S_3 + 4}{3 + 2S_3} = \cfrac{3\times \frac{41}{25} + 4}{3+ 2 \times \frac{41}{25}} = \cfrac{\frac{123 + 116}{29}}{\frac{87 + 82}{29}} = \frac{239}{169} \simeq 1.414$

$S_5 = \frac{3S_4 + 4}{3 + 2S_4} = \cfrac{3\times \frac{239}{165}+4}{3+2\times \frac{235}{169}}= \cfrac{\frac{717+676}{169}}{\frac{507 + 478}{169}} = \frac{1393}{985} \simeq1.414213$

$\lim\limits_{n \to \infty} S_n = \sqrt 2$

$\lim\limits_{n \to \infty} (2^{n/2} + (\frac \pi 4)^n)^\frac 1n$ $(\infty \; type)$

$= Exp \left\{\lim\limits_{n\to \infty} \frac{log(2^{n/2} + (\frac\pi4)^n)}{n}\right\}$ $(\frac \infty \infty \; type)$

$= Exp \left\{\lim\limits_{n\to \infty} \cfrac{2^{n/2}\frac{log2}2 + (\frac \pi4)^n log (\frac \pi4)}{2^{n/2} + \left(\frac \pi4\right)^n}\right\}$

$= Exp\left\{ \lim\limits_{n\to \infty} \cfrac{\frac12 log2 + \left(\frac\pi4\right)^n log(\frac\pi 4)2^{-n/2}}{1+ (\frac \pi4)^n \,2^{-n/2}}\right\}$

$= e^{\frac 12 log 2} = e^{log2^\frac12} = 2^\frac12 = \sqrt 2$

$\therefore \frac{\lim\limits_{n\to \infty } S_n}{\lim\limits_{n\to \infty} \left(2^\frac n2 + (\frac \pi 4)^n\right)^\frac1n} = \frac{\sqrt 2}{\sqrt 2} = 1$

= X + XY + XZ + YZ = X(1 + Y) + Z(X + Y)

= X + XZ + YZ (X . 1 = X property of 0 and 1)

= X(1 + Z) + YZ

= X.1 + YZ (1 + Z = 1 property of 0 and 1)

27.

Calculate Debt-equity ratio.

Answer»

Deb-equity ratio = (Total long term debts)/(Shareholders fund)

Total long term deb = Debentures + Long term ratio

= 2,00,000 + 1,00,000

= Rs. 3,00,000

Share holders funds = Equity share capital + General Reserve

= 4,00,000 + 3,00,000

= Rs. 7,00,000

∴ Deb equity ratio = 3,00,000/ 7,00,000

= 0.43 : 1

28.	Discuss the definition of Political science.
Answer» Political science is that branch of the social sciences that studies the state, politics, and government. Political Science deals extensively with the analysis of political systems, the theoretical and practical applications to politics, and the examination of political behavior. The Greek thinker, Aristotle, defined political science as the study of the state. Many political scientists view themselves as being engaged in fleshing out the connections between political events and conditions, and by this understanding they hope to construct a system of general principles that posit the way the world of politics works. Political science is not a standalone field and it intersects many other branches like sociology, economics, history, anthropology, public policy among others. Political scientists are much sought after these days because of the changing landscape of politics across the world and since the society wants to understand how the political world works, they need someone to explain the nuances of the political economy. Any casual perusal of the newspapers and the television channels reveals that political scientists are at the forefront of debates and discussions for their knowledge and expertise.

45.	A block of mass `1kg `is placed on a rough horizontal surface. A spring is attached to the block whose other end is joined to a rigid wall, as shown in the figure. A horizontal force is applied on the block so that it remains at rest while the spring is elongated by `x(xge(mumg)/(k))`. Let `F_(max)` and `F_(mi n)` be the maximum and minimum values of force `F` for which the block remains in equilibrium. For a particular `x, F_(max)-F_(mi n)=2N`. Also shown is the variation of `F_(max)+F_(mi n)` versus `x`, the elongation of the spring. The spring constant of the spring is `:`A. `25N//m`B. `20N//m`C. `2.5N//m`D. `50N//m`
Answer» Correct Answer - A `F_(max)+F_(min)=2kx ....(1)` from graph `F_(max)+F_(min)=5` and `x=0.1` Putting in equation `(1)` `t=2k(0.1)` `k=25N//m`.

46.	A block of mass `1kg `is placed on a rough horizontal surface. A spring is attached to the block whose other end is joined to a rigid wall, as shown in the figure. A horizontal force is applied on the block so that it remains at rest while the spring is elongated by `x(x ge (mumg)/(k))`. Let `F_(max)` and `F_(mi n)` be the maximum and minimum values of force `F` for which the block remains in equilibrium. For a particular `x, F_(max)-F_(mi n)=2N`. Also shown is the variation of `F_(max)+F_(mi n)` versus `x`, the elongation of the spring. The coefficient of friction between the block and the horizontal surface is `:`A. `0.1`B. `0.2`C. `0.3`D. `0.4`
Answer» Correct Answer - A `F_(max)=kx+mu mg` `F_(min)=kx-mu mg` `:. F_(max)-F_(min)=2mu mg` or `2=2mu 10` `:. M=0.1`

Also shown is the variation of `F_(max)+F_(mi n)` versus `x`, the elongation of the spring. The value of `F_(mi n)`, if `x=3cm` is `:`
Answer» Correct Answer - A When `x=0.03` `kx=25xx0.3` `=0.75N`, which is less than `mu mg=0.1xx10=1N` `:. ` The block will be at rest, without applying force `F`.

49.	What do you understand by composite fish culture?
Answer» Composite fish culture is the method to culture five or six species, both indegenous and exotic, together in a single fish pond. These species are selected so that they do not compete for food among themselves having different types of food habits. As a result food available in all the parts of the pond is used. For example— Catlas are surface feeders, Rohu is middle zone feeder and Mrigals and common carps are bottom feeders.

50.

Define the term hybridization and photoperiod.

Answer»

Hybridisation— Hybridisation refers to crossing between genetically dissimilar organisms.

Photoperiod— Duration of sunlight available to the plant is called as photoperiod. It affects the growth, flowering and maturation of crops.
