a huge iceberg is found floating an the ocean's current. suppose an iceberg is 120 km long, 35 km wide, and 230m thickness. (a) how much heat is needed to melt this iceberg (at 0˚C). (b) assuming that the annual energy consumption is 9.3 x 10^19 J. if this energy is delivered to the iceberg every year, how many years would it take before the ice melts? (density of ice is 970 kg/m^3)
