An electron is moving through a magnetic field whose magnitude is 9.21 × 10^-4 t. the electron experiences only a magnetic force and has an acceleration of magnitude 2.30 × 10^14 m/s^2. at a certain instant, it has a speed of 7.69 × 10^6 m/s. determine the angle (less than 90°) between the electron's velocity and the magnetic field.

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?
