143317 A wooden rod of uniform cross-section and of length $120 \mathrm{~cm}$ is hinged at the bottom of the tank which is filled with water to a height of $40 \mathrm{~cm}$. In the equilibrium position, the rod makes an angle of $60^{\circ}$ with the vertical. The center of buoyancy is located on the rod at a distance (from the hinge) of
143322 A block is being hung in air from a wire which is stretched over a sonometer. The bridges of the sonometer are $L \mathrm{~cm}$ apart when the wire is in unison with a tuning fork of frequency $N$. When the block is completely immersed in water, the length between the bridges is $l \mathrm{~cm}$ for re-establishing unison. The specific gravity of the material of the block is-
