1. The problem statement, all variables and given/known data 17.While cruising the North Atlantic in a fog, a ship blew its horn, and received an echo from an iceberg 4.0 s later. The temperature of the air was 5°C, the temperature of the iceberg was 0°C, and the temperature of the water was 2°C In order to calculate the distance from the ship to the iceberg, the captain must also know the speed of sound in: A. ice at 0°C. B. water at 2°C. C. water at 0°C. D. air at 0°C. E. air at 5°C. 2. Relevant equations n/a 3. The attempt at a solution If there were no fog the answer would definitely be E, but since there is a significant amount of water in the air I thought the answer was B. Turns out the water doesn't make a difference because the answer sheet says E. Could somebody please explain?
