What is the potential difference across a 2.0-ohm resistor that draws 2.0 coulombs of charge per second

Potential difference ('voltage') = (resistance) x (current)

Current = charge/time

Current in this one = (2 coulombs/sec) = 2 Amperes

Potential difference = (2 ohms) x (2 Amperes)

Potential difference = 4 volts

it will be pushed away from the source of the electric field. a negative charge in a cloud induces a positive charge in the ground below the cloud.

explanation:

prolly a beacuse the momentuem the car has increases while going down hill
