They use GPS (Global Positioning System) where the ship etc searches for as many radio signals from geosynchronous orbit satellites as it can get. It then triangulates its position by determining the direction and angle that it receives the signals. Same process that modern airliners use.

What does it means if you hear a sound by the gas tank when you turn the ignition to the On position?
In modern cars there is usually an electric fuel pump, either actually in the tank or just nearby. That's probably what you're hearing.
What era brought the introduction of pottery?
Pottery is still used in the undeveloped countries. ADDED: It is still used in the developed countries too! The discovery that clay can be shaped and fused into useful objects goes back at least around 3000 years; and the styles of a lot of surviving Bronze Age vessels are just as elegant as many equivalents by modern potters.
What is the modern Guinevere?
in modern language, Guinevere means Jennifer.
Does a crank shaft sensor control the fuel injection timing?
There are multiple sensors used to control fuel injection in an engine. Depending on the year, make, and model or the vehicle, there could be upwards of 20 sensors used to determine the amount of fuel injected into an engine.For most modern cars, the primary sensors, which the computer uses to determine fuel needs, are the Oxygen (O2), the Mass Air Flow (MAF), and the Crank/Cam positions sensors.The O2 sensor measures the amount of oxygen in the post combustion exhaust stream, and determines if the engine is running lean (not enough fuel) or rich (too much fuel).The MAF sensor measures the amount of air coming in through the vehicle's intake manifold, and determines the amount of fuel needed for the volume of air the engine is moving.The Crank/Cam position sensor measures the position of either the crankshaft or the camshaft, and tells the computer if the engine is running or not; if this sensor is not working, the fuel injectors will not deliver fuel to the engine.
Why would it be so catastrophic for Amelia Earhart to not know latitude or longitude?
This all has to do with navigation. In order to go from point A to point B you have to have a starting point of reference which is point A. Then you need to know your direction of travel typically by using a compass. If you knew your exact speed you would not need to know your position. However, a plane traveling in the air (over the ocean in this case) is subjected to cross winds, tail winds, head winds and other forces which do not allow the navigator to accurately determine speed and direction. These can be estimated with some accuracy but the further you go away from the known point of reference the greater the error. So knowing your position (Latitude and Longitude) is critical since the plane has a limited amount of fuel and would need to go from Point A to Point B as directly as possible. During the time Amelia Earheart flew, the only way to determine your position was by using the relative position of the Sun and stars (celestial navigation). The problem with celestial navigation is that it was not that accurate mostly on the order of 0.5 to 1.0 nautical mile (6080 feet) at its best. On cloudy days this method cannot be done and you fall back to time, speed and direction which is an estimate. So if you are trying to find a small island in the middle of the Pacific ocean that is 0.5 miles wide, it is VERY easy to get lost by missing your target. Today we has modern satellites that can give you your Latitude and Longitude to within a few centimeters. This is called GPS (Global Positioning System).
