Chapter 11, Problem 19Q
In the battle of the Falkland Islands in 1914, the shots of British gunners initially fell wide of their marks because their calculations were based on naval battles fought in the Northern Hemisphere. The Falklands are in the Southern Hemisphere. Explain the origin of their problem.

A person is standing at the edge of the water and looking out at the ocean (see figure). The height of the person's eyes above the water
is h = 1.9 m, and the radius of the Earth is R = 6.38 x 106 m.
(a) How far is it to the horizon? In other words, what is the distance d from the person's eyes to the horizon? (Note: At the horizon the
angle between the line of sight and the radius of the earth is 90°.)

- You receive orders to sail due east for 28.2 mi to put your salvage ship directly over a sunken pirate ship. However, when your divers probe the ocean floor at that location and find no evidence of a ship, you radio back to your source of information, only to discover that the sailing distance was supposed to be 28.2 nautical miles, not regular miles. Use the Length table below to calculate how far horizontally you are from the pirate ship.arrow_forwardExplain the solution on how to solve this step by step ?
