A person notices a mild shock if the current along a path through the thumb and index finger exceeds 77 μA. Compare the maximum possible voltage without shock across the thumb and index finger with a dry-skin resistance of 4.4 ✕ 105 Ω and a wet-skin resistance of 1,750 Ω.

Maximum possible voltage without shock across the thumb and index finger with a dry-skin = 33.88 V

Maximum possible voltage without shock across the thumb and index finger with a wet-skin = 0.135 V

Explanation:

From Ohm's law

V = IR

For the maximum possible voltage without shock for dry skin, the

R = 4.4 × 10⁵ Ω

I ≤ 77 μA

I ≤ 77 × 10⁻⁶ A

V ≤ 4.4 × 10⁵ × 77 × 10⁻⁶ = 33.88 V

For the maximum possible voltage without shock for dry skin, the

R = 1750 Ω

I ≤ 77 μA

I ≤ 77 × 10⁻⁶ A

V ≤ 1750 × 77 × 10⁻⁶ = 0.13475 V

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
