From the equation we are told that:
Velocity of French sub 
Velocity of U.S. sub at 
French Wave Frequency 
Velocity of wave 
Generally the equation for Signal's frequency as detected by the U.S. is mathematically given by
Doppler effect
9.8ms^-2 as it is being pulled back down by gravity
Answer:this is obviously because free electrons can easily move in the metal due to potential difference, and they are inserted in the wire from the negative terminal of the battery and pulled away ( come back) from the wire into the battery at positive terminal.
