Answer:
0.044 V
Explanation:
E = Electric field = 
d = Thickness of membrane = 8 nm
When the electric field strength is multiplied by the membrane thickness we get the voltage
Voltage across a gap is given by

The voltage across the membrane is 0.044 V
Answer:
rolling ball down a hill
Explanation:
A rolling ball has kinetic energy
Answer:
option c
Explanation:
The temperature must be constant. Ohms law states that the current running through a conductor is directly proportional to the potential difference across it provided the temperature remains constant
