Find two irrational numbers between 4/9 and 7/11

Answers:

4/9 and 7/11
LCM of 9 and 11 is 99.
Hence,
4 × 11/ 9 × 11 = 44/99
7 × 9/ 11 × 9 = 63/99
2 rational numbers between 4/9 and 7/11 are 45/99 and 46/99

What does it represent ?

Answers:

In physics, the Poynting vector represents the directional energy flux density (the rate of energy transfer per unit area) of an electromagnetic field. The SI unit of the Poynting vector is the watt per square metre (W/m^{2}).
The Poynting vector is defined as
<dl> <dd></dd> </dl>where
 E is the electric field vector;
 H is the magnetic field's auxiliary field vector.
 S is Poynting vector

When a wire of resistance R is streched and its radius becomes r/2 , then new resistance is ?

Answers:

Ans. Let the Initial Length of Wire = l
Final length of Wire = L
Intial Radius of wire = r
FInal Radius of Wire r_{1} = {tex}r\over 2{/tex}
So, Initial Volume of Wire = Final Volume of Wire
{tex}=> \pi r^2 l = \pi r_1^2L{/tex}
{tex}=> r^2 l = ({r\over 2})^2L{/tex}
{tex}=> r^2 l = {r^2\over 4}L{/tex}
{tex}=> L = 4l{/tex}
Initial Area of Cross Section of wire (A) = {tex}\pi r^2{/tex}
Final area of Cross section of wire (A') = {tex}\pi r_1^2 = \pi{r^2\over 4}{/tex}
Initial Resistance of Wire (R)= {tex}\rho {l\over A} = \rho {l\over \pi r^2}{/tex}
Final Resistance of Wire (R') = {tex}\rho {L\over A'} = \rho {4l\over {\pi r^2\over 4}} ={ \rho 4\times 4l\over\pi r^2}{/tex}
= {tex}16\rho{l\over \pi r^2} = 16R{/tex}
So new Resistance ll be 16 times of initial Resistance.

 A room,: length = 5m breadth = 3.5m height = 3m. Find the cost of cementing the inner portions of the wall at Rs. 20 per sq metre
 Each edge of a cube is incresed by 50%. Find the percentageincrease in the SURFACE AREA of the cube.

Answers:

(1)
Dimensions of room :
l = 5m ; b = 3.5m ; h= 3m
LSA of room = 2(l+b) x h
= 2 ( 5 + 3.5) x3
= 6 x 8.5
= 52 m^{2}
1 m^{2} = Rs. 20
52 m^{2} = Rs. 20 x 52 = Rs. 1040
(2)
Let the edge of the cube be 'a'
Surface area = 6a^{2}
Let the edge be increased by 50% so the new edge becomes = a + (a/2) = 3a/2
New Surface area = 6 (3a/2)^{2} = 27a^{2}/2
Percentage increase = [Change in Increase/ Original] x 100
= [(27a^{2}  12a^{2})/ 6a^{2} x 2 ] x 100
(5 x 100 )/4
5 x 25 = 125%
