Iceberg. The “tip of the iceberg” in popular speech has come to mean a small visible fraction of something that is mostly hidden. (a) For real icebergs, what is this fraction? The density of ice is \(\rho_i = 917 \text{ kg/m}^3\) and the density of the seawater is \(\rho_w = 1024 \text{ kg/m}^3\). In September 2019, a huge iceberg calved off the Amery Ice Shelf in East Antarctica. Named D28, it had a top surface area of \(1636 \text{ km}^2\) (larger than Greater London) and a thickness of \(200 \text{ m}\). (b) What is the weight of the ice in D28?
