Once water has been heated to its boiling point, additional heating will not raise its temperature. what happens to this additional energy? a. energy was used to change phase of water from liquid to gas (evaporation). it is radiated back into the atmosphere from the stove. b. the extra energy is absorbed by the water and is stored for use at a later time. c. extra energy is turned into potential energy and is stored in the liquid water molecules. d. energy was used to change phase of water from liquid to gas (evaporation). it is stored in the water vapor produced.

We all use gps today, even if we don't drive yet. i bet you have been in the car with a parent and they have asked you to get out your phone to find a specific location. in your car, on the phone, you are using a very sophisticated technology. gps satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. gps receivers take this information and use trilateration to calculate the user's exact location. essentially, the gps receiver compares the time a signal was transmitted by a satellite with the time it was received. the time difference tells the gps receiver how far away the satellite is. now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map. what type of signal is utilized by the gps satellite?
