How many coulombs of charge enter a 1.20 cm length of the axon during this process?
galina1969 [7]
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

Which pair does NOT have an electric force between them?
fenix001 [56]

Answer:

Two Neutral

Explanation:

If; One postive, and one negative they would be attracked. >-<

If; one postive and the other was postive, (or vice versa) they would repel <->

they both have an electrical charge, and force.

Neutral's are Nueatral. they have to opisition or attraction= No electrical force.

What is the relationship between amplitude and frequency of a wave?.
Fynjy0 [20]

Answer:

Inversely proportional

Explanation:

The amplitude and frequency of a wave have an inverse connection, with the amplitude being inversely proportional to the frequency. As the frequency rises, the amplitude falls. As the frequency decreases, the amplitude increases.

An open system is a system where __________.
alexandr402 [8]

Answer:

Can enter or leave the system matter and energy. (The correct option is D)

Explanation:

Open system is defined as the system where exchange of matter, and energy occurs with its surrounding, presenting breaking down, and build up of its materials, and import, export of components.

Open system transfer the material into, and out of the system boundary, it contains an external interaction. A good example of open system is living things they actively connect with its environment, in results it shows changes in both the environment, and the living things.

So, the correct option is D.
