Answer:
Explanation:
For this case we have the following info given:
Number of Na+ ions
Each ion have a charge of +e and the crage of the electron is
The time is given if we convert this into seconds we got:
Now we can use the following formula given from the current passing thourhg a meter of nerve axon given by:
Where N represent the number of ions, e the charge of the electron and Q the total charge
If we replace on this case we have this:
And from the general definition of current we know that:
And since we know the total charge Q and the time we can replace:
The current during the inflow charge in the meter axon for this case is
Answer:
Decreases by times
Explanation:
The intensity of a sound is defined as the energy of the sound that is flowing in an unit time through the unit area which is in the direction that is perpendicular to the direction of the sound waves movement.
The intensity of energy is described by the inverse square law. It states that the intensity varies inversely with the distance square of the distance.
In other words, the sound intensity decreases as inversely proportional to the squared of the distance. i.e.
In the context when the distance was 3 m, the intensity of the sound was =
But when the distance became 6 cm or 0.06 m, the sound intensity decreases by =
= times
