Homework Help: physics

Posted by anonymous on Sunday, April 15, 2012 at 9:38pm.

Icebergs in the North Atlantic present hazards to shipping, causing the length of shipping routes to increase by about 30 percent during the iceberg season. Attempts to destroy icebergs include planting explosives, bombing, torpedoing, shelling, ramming, and painting with lampblack. Suppose that direct melting of the iceberg, by placing heat sources in the ice, is tried. How much heat is required to melt 9 percent of a 2.50105 metric-ton iceberg? One metric ton is equal to 103 kg. Assume that the iceberg is at 0C. (Note: To appreciate the magnitude of this energy, compare your answer to the Hiroshima atomic bomb which had an energy equivalent to about 15,000 tons of TNT, representing an energy of about 6.01013 J.)
