You are doing a measurement to determine the conductance of an artificial membrane. The membrane is selectively permeable to Na
. The temperature is 15 degrees C The external concentrate of Na is 500 mM The internal concentration of Na is 70 mM Using a voltage clamp apparatus you clamp the membrane voltage (Vm) at 20 mV At this clamped voltage you measure a current of -71 nA What is the membrane's conductance

Explanation:
The energy of electron in any state is given by here h is planck's constant n is state of electron L is the infinte potential well m is the mass of electron
We know that
Potential well dimension =
Mass of electron
So energy required to electron to jump from ground state to 3rd state
Answer:
The given statement concerning distance and displacement is true.
Explanation:
If any point travels along any path between two points A and B the distance it travels is the length of the actual path it travels.
Mathematically the distance between two points is the algebraic sum of the infinitesimal distances that the particle travels.
Mathematically
Displacement by definition is the shortest distance between the initial and final positions of the particle and is given by the straight line joining the two points.
Since a line is the shortest path that exists between 2 points thus it will be always smaller than any other path connecting the 2 points hence will be smaller than the distance.
While as if the object travels along a straight line without changing it's direction the distance in that case equals the displacement.
