How can you determine your geographic location based on the time of day?
Having only one piece of information, such as the time of day, wouldn't allow you to determine your geographic position. You would have to have additional information such as the position of the sun (or stars) at a particular time of day in order to accurately determine your position. There is an excellent PBS piece on this at: http://www.pbs.org/wgbh/nova/teachers/ideas/sammons/packet.html
As much as they can get away with!!! Just joking..... Are you asking about an electricity provider? They charge by the kilowatts used based on a published rate structure. If you are asking about companies that charge for electrician's labor, the joke I started with is pretty close to the truth but the actual amount varies by geographic location, the length of the job, the tools needed, the distance to the job, the time of…
One can determine the best location to place a clock by simply working out at what angle a clock looks aesthetically pleasing, and whether the location is efficient for telling the time, and looks good. It is best to place clocks in the middle of walls and to make sure the colour of the clock doesn't clash with surrounding wall colours, and to make sure the time can be seen from as many angles and…
Can gps determine speed of vehicle and does a gps account for the change in elevation when determining the distance traveled?
Yes. Global positioning satellite systems pinpoint their position using time and distance calculations received from the various GPS satellites. If a GPS systems pinpoints a location at a certain time, and pinpoints a different location at a certain time later, all that is needed to determine how fast the GPS got from the first point to the second is simple math.
If you live in Montana where there is not sales tax but purchase items from South Dakota totaling over five hundred dollars do you still have to pay sales tax?
It is Grenwich Mean Time. There is an astronomical observatory in the city of Greenwich, England, which is able to determine the exact time at its own location (of course, since the introduction of GMT, other even more precise methods of measuring time have been invented) which is why that location was chosen as the starting point for all the time zones of the world, whose time is measured relative to that of Greenwich.
