The period of a pendulum T depends on the mass of bob M length of the trends L and the acceleration due to gravity G use period of dimensions to find an expression for T

Answer»

Answer:

Given;

$\longrightarrow \: \sf T\propto [M]^a [L]^b [g]^c\\$

Adding k as dimensionaless CONSTANT we have :

$\longrightarrow \: \sf T = k [M]^a [L]^b [g]^c$

$\footnotesize\dag \: \bf{Dimensions \: of \: Time \: Period \: (T) = [M^0 L^0T ^{1} ]} \\$

$\footnotesize\dag\:\bf{Dimensions \: of \: mass \: (M) = [M^1 L^0 T^0]} \\$

$\footnotesize\dag\: \bf Dimensions \: of \: length \: (L) = [M^0L^1T^0]$ $\footnotesize\dag\: \bf Dimensions \: of \: Acceleration \: due \: gravity \: (g) = [M^0L^1T^{-2}] \\$

$\longrightarrow \: \sf [M^0L^0T^1] = [M^1 L^0 T^0]^a [M^0L^1T^0]^b [M^0L^1 T^{-2}]^c \\$

$\longrightarrow \: \sf [M^0L^0T^1] = [M]^a[L]^{b+ c} [ T]^{ - 2c }\\$

On comparing the POWERS of LHS and RHS we get:

$\dashrightarrow\sf a = 0 \\$

$\dashrightarrow\sf b + c= 0 \\$

$\dashrightarrow\sf b= - c \qquad \: ...(i)$

$\dashrightarrow\sf -2c= 1 \\$ $\dashrightarrow\sf c= \dfrac{1}{- 2} \qquad \: ...(ii)\\$

Substituting the VALUE of c from eqⁿ (ii) to eqⁿ (i) we get :

$\dashrightarrow\sf b = - \bigg(\dfrac{1}{-2} \bigg) \\$

$\dashrightarrow\sf b = \dfrac{1}{2}$ $\longrightarrow \: \sf T = k [M]^0 [L]^{ \frac{1}{2} } [g]^{ \frac{1}{ - 2} } \\$

$\longrightarrow \: \sf T = k [L]^{ \frac{1}{2} } [g]^{ \frac{1}{ - 2}} \\$

$\longrightarrow \: \sf T = k \dfrac{[L]^{ \frac{1}{2} } }{[g]^{ \frac{1}{2}}} \\$

$\longrightarrow \: \sf T = k \dfrac{\sqrt{[L] }}{\sqrt{[g]}} \\$

$\longrightarrow \: \sf T = k \sqrt{ \frac{L}{g} } \\$

EXPERIMENTALLY we know that the value of k is 2π, Hence :

$\longrightarrow \: \gray{\underline{ \boxed{\orange{\rm T = 2\pi \sqrt{\frac{L}{g}}}}}}\\$

1592.	The coeficient of magnetic coupling between two coils is minimum?a) when the coils are wound on the same ferrite (iron) rodb) for air-cored coils with coil axes parallelc) for air-cored coils with axis perpendicular d) for ferrite-cored coils with coil axes perpendicular.
Answer» Explanation: COEFFICIENT of coupling is always less than unity, and has a maximum value of 1 (or 100%). This case, for which K = 1, is called perfect coupling, when the ENTIRE FLUX of one coil links the other.

1593.	What relation exists among resistance, length and cross - sectional area?
Answer» ANSWER: The relationship between RESISTANCE and WIRE length is proportional . The resistance of a thin wire is greater than the resistance of a thick wire because a thin wire has fewer ELECTRONS to carry the current. The relationship between resistance and the AREA of the cross section of a wire is inversely proportional .

Answer» প্রদত্ত, জলের পরিমাণ = 36 গ্রাম নির্ণেয়, প্রদত্ত পরিমাণ জল উৎপন্ন করতে কত গ্রাম হাইড্রোজেন লাগবে? সমাধান, নিম্নলিখিত গাণিতিক পদ্ধতিতে আমরা সহজেই গাণিতিক সমস্যার সমাধান করতে পারি। এখন আমরা জানি যে, 1 মোল জল = (1X2)+16 = 18 গ্রাম জল সুতরাং, 18 গ্রাম জল = 1 মোল জল 1 গ্রাম জল = 1/18 মোল জল 36 গ্রাম জল = 36/18 = 2 মোল জল এখন, 1 মোল জলে থাকে = 2 গ্রাম হাইড্রোজেন 2 মোল জলে থাকবে = 2X2 = 4 গ্রাম হাইড্রোজেন অতএব, 36 গ্রাম জল উৎপন্ন করতে 4 গ্রাম হাইড্রোজেন লাগবে।

36 গ্রাম জল উৎপন্ন করতে কত গ্রাম হাইড্রোজেন লাগবে ?

Answer»

প্রদত্ত,

জলের পরিমাণ = 36 গ্রাম

নির্ণেয়,

প্রদত্ত পরিমাণ জল উৎপন্ন করতে কত গ্রাম হাইড্রোজেন লাগবে?

সমাধান,

নিম্নলিখিত গাণিতিক পদ্ধতিতে আমরা সহজেই গাণিতিক সমস্যার সমাধান করতে পারি।

এখন আমরা জানি যে,

1 মোল জল = (1X2)+16 = 18 গ্রাম জল

সুতরাং,

18 গ্রাম জল = 1 মোল জল

1 গ্রাম জল = 1/18 মোল জল

36 গ্রাম জল = 36/18 = 2 মোল জল

এখন,

1 মোল জলে থাকে = 2 গ্রাম হাইড্রোজেন

2 মোল জলে থাকবে = 2X2 = 4 গ্রাম হাইড্রোজেন

অতএব, 36 গ্রাম জল উৎপন্ন করতে 4 গ্রাম হাইড্রোজেন লাগবে।
