39. Let iVbe the total volume of the iceberg. The non-visible portion is below water, and thus the volume of this portion is equal to the volume fVof the fluid displaced by the iceberg. The fraction of the iceberg that is visible is frac1iffiiVVV−==−.Since iceberg is floating, Eq. 14-18 applies:.gifFmgmgmm¡=SincemVρ=, the above equation implies fif fVVρρ=¡=.Thus, the visible fraction isfrac 11fiVV=− =−(a) If the iceberg (
