Two objects carry initial charges that are q1 and q2, respectively, where |q2| > |q1|. they are located 0.160 m apart and behave like point charges. they attract each other with a force that has a magnitude of 1.30 n. the objects are then brought into contact, so the net charge is shared equally, and then they are returned to their initial positions. now it is found that the objects repel one another with a force whose magnitude is equal to the magnitude of the initial attractive force. what are the magnitudes of the initial charges on the objects?

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?
