During the inflow part of a cycle in the neurons approximately 5.6 × 10∧11 Na ions per meter, each with a charge of +e enter the axon.
Therefore, ions will be (5.6 ×10∧11) × (1.2/100)
= 6.72 × 10 ∧8 Na ions
Charge of an electron is 1.6 × 10∧-19 Coulombs
Thus; 6.72 ×10∧ 8 ×1.6 ×10∧-19 = 1.0752 ×10∧-10 coulombs

The physical change is that it changed shapes it never changed its chemical identity it would be different if the spring was rusted it's like how you can rip a piece of paper in half and it is still paper
Screw gauge or micrometer screw gauge is a measuring instrument used for precision measurement. A measuring device used extensively in the mechanical engineering field.
Hope this helps :)
Answer:
initially- with positive potential differences - the current is directly proportional to the p.d. However, as the current through the filament increases, the heating effect caused in the lamp also increases and so the temperature of the filament rises. This increase in the filament's temperature also increases the resistance of the filament. As a result the rate of increase of the current decreases and a greater change in the potential difference is required to cause a change in the current. This can be seen on the curve as the gradient becomes more shallow (greater resistance). This same pattern is repeated when a negative potential difference is applied across the filament
