A copper block is suspended from a wire, as in part 1 of the drawing. A container of mercury is then raised up around the block, as in part 2, so that 53.0% of the block's volume is submerged in the mercury. The density of copper is 8890 kg/m3, and that of mercury is 13 600 kg/m3. Find the ratio of the fundamental frequency of the wire in part 2 to the fundamental frequency in part 1.
