39. Let i V be 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 f V of the fluid displaced by the iceberg. The fraction of the iceberg that is visible is frac 1 if f ii VV V == . Since iceberg is floating, Eq. 14-18 applies: . g i f Fm g m g mm ¡ = Since mV ρ = , the above equation implies f i f f V V ρρ = ¡ = . Thus, the visible fraction is frac 1 1 f i V V =− =− (a) If the iceberg (
