A skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 8.8° with the horizontal. The rope moves parallel to the slope with a constant speed of 0.55 m/s. The force of the rope does 880 J of work on the skier as the skier moves a distance of 4.2 m up the incline. (a) If the rope moved with a constant speed of 2.1 m/s, how much work would the force of the rope do on the skier as the skier moved a distance of 4.2 m up the incline? At what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.55 m/s and (c) 2.1 m/s?

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?
