The beat frequency is ωbeat = |ω1−ω2|. In the experiment, you measure periods.
Re-express the beat period in terms of the fundamental periods T1 and T2, Which of the following expressions is correct?

A) T = T1T2 / (T2-T1)
B) T = T2-T1/ T1T2
C) T = T1T2 / 2πT2 - T1
D) T = 2πT2 - T1 / T1T2

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?
