A light pipe known as optical fibre used to facilitate visual examination of internal organs is based on:

The ratio of maximum frequency and minimum frequency of light emitted in Balmer series of hydrogen spectrum is

The angle of minimum deviation of an equilateral prism is equal to its refracting angle. The refractive index of the material of the prism is :

If the temperature of a metallic conductor is increased, then the product of resistivity and conductivity

The figure shows a long cylindrical straight wire of radius a carrying steady current (I). The current (I) is uniformly distributed across the cross-section of the wire. The ratio of the magnetic fields at points \(r=\frac{a}{3}\) and \(r=\frac{a}{2^{\prime}}\) respectively is: Here r is the distance of point from the axis of cylinder.

The refractive indices of glass and water are \( \frac{3}{2} \) and \( \frac{4}{3} \), respectively. If the speed of light in water is \( 2.25 \times 10^8 \, \text{m/s} \), the speed of light in glass will be:

Light of uniform intensity shines perpendicularly on a totally absorbing surface, fully illuminating the surface. If the area of the surface is decreased, what is the effect on radiation pressure ?

The behavior and pattern of the data in a time series is NOT based on which of the following component?

If the function \(f(x)=\left\{\begin{array}{ll}\frac{\sin 5 x}{3 x}, & x \neq 0 \\ \frac{k}{3}, & x=0\end{array}\right.\) is continuous at \(x=0\), then \(k^2-2 k+10\) is equal to:

When \(_{92}^{232}Th\) changes into \(_{82}^{208}Pb\) the number of \(\alpha\) and \(\beta\) particles emitted are

Read the passage carefully and answer the questions based on the passage:
Pollen pistil interaction involves all events from the landing of pollen grains on the stigma until the pollen tube enters the embryo sac (when the pollen is compatible). When a pollen tube grows through the style and enters into the ovules, it finally discharges two male gametes in one of the synergids. Syngamy and triple fusion are two fusion events occur in angiosperms. Thus, angiosperms exhibit double fertilization. The products of these fusions are the diploid zygote and triploid primary endosperm nucleus. Zygote develops into embryo and primary endosperm cell forms the endosperm tissue. The developing embryo passes through different stages before maturation.
Formation of diploid zygote is a result of:

Match List I with List II

LIST I	LIST II
A. If \(A^{-1}=\left[\begin{array}{ll}3 & 4 \\ 5 & 6\end{array}\right]\) then \(A\) is	I. \(\left[\begin{array}{ll}5 & 2 \\ 7 & 3\end{array}\right]\)
B. If \(A=\left[\begin{array}{cc}2 & -1 \\ 3 & 1\end{array}\right]\) then \(A A^T\) is	II. \(\left[\begin{array}{ll}0 & 1 \\ 1 & 0\end{array}\right]\)
C. If \(A^{-1}=\left[\begin{array}{ll}5 & 7 \\ 2 & 3\end{array}\right]\) then \(\left(A^T\right)^{-1}\) is	III. \(\left[\begin{array}{cc}-3 & 2 \\ \frac{5}{2} & -\frac{3}{2}\end{array}\right]\)
D. If \(A=\left[a_{i j}\right]_{2 \times 2}\) where \(a_{i j}=(i-j)^2\), then \(A\) is	IV. \(\left[\begin{array}{cc}5 & 5 \\ 5 & 10\end{array}\right]\)

(B) This act intends to reduce illegal abortions and consequent maternal mortality and morbidity.
(C) If the continuation of pregnancy involves a risk to the life of a pregnant woman, it can be terminated by the opinion of 3 government registered medical practitioners.
(D) If there is a substantial risk that the child born will be seriously handicapped, pregnancy can be terminated even if lasted for more than 12 weeks, but fewer than 24 weeks by the opinion of two government registered medical practitioners.
