What is the mass in mev and in kg (both to decimal places) of an electron whose speed is half the speed of light? mass in mey- mass in kg- b. what is the momentum of this electron, in kg. s-. and in mev (both in 3 decimal places)? momentum of this electron, in kg·s-1= momentum in mev/c c. what would be the energy (in ey) of a photon with the same speed energy of photon in ev-

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?

Often called simply "velocity," this is the velocity of an object at a particular moment in time.

Along wire carrying a 4.2 a current perpendicular to the xy-plane intersects the x-axis at x=−1.7cm. a second, parallel wire carrying a 3.0 a current intersects the x-axis at x=+1.7cm. part a at what point on the x-axis is the magnetic field zero if the two currents are in the same direction? express your answer to two significant figures and include the appropriate units.
