C = q/V

Where C is in farads and q is C

Question 22

How does depolarization occur?

Answer 22

the gated sodium ion channels on the neuron’s membrane suddenly open and allow sodium ions (Na+) present outside the membrane to rush into the cell.

Question 23

How is the spring constant related to PE?

Answer 23

PE = ½kx^2

where k is the spring constant in N/m and x is the displacement
