At what angle should an unpolarised beam be incident on a crystal of refractive index $\mu = \sqrt{3}$,so that the reflected beam is completely polarised (in $^o$)?

The perpendicular distance from the point $(1, \pi)$ to the line joining $(1, 0^{\circ})$ and $(1, \frac{\pi}{2})$ (in polar coordinates) is:

Which hormone is responsible for apical dominance?

The solubility of barium iodate in an aqueous solution prepared by mixing $200 \ mL$ of $0.010 \ M$ barium nitrate with $100 \ mL$ of $0.10 M$ sodium iodate is $X \times 10^{-6} mol dm ^{-3}$. The value of $X$ is $.....$
Use: Solubility product constant $\left(K_{ sp }\right)$ of barium iodate $=1.58 \times 10^{-9}$
