During which stage of developing the global positioning system did engineers first apply the theory of relativity
to design the product?
The global positioning system (GPS) uses
electromagnetic waves sent between computer devices
on Earth and satellites in space to automatically
determine the exact position of the computer device on
Earth. In order to create this technology, engineers had
to apply Einstein's theory of relativity, which explains
how electromagnetic waves change direction in space.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
