Answer:
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:It isn’t
Explanation:
Air isn't considered a pure substance because there is no one single chemical element of compound that forms air. Air is a mixture of various pure chemical substances, most of which exist in the gaseous state.
They make up a Complex Machine.
Answer:
Generally speaking, as the human population grows, our consumption of natural resources increases. More humans consume more freshwater, more land, more clothing, etc. ... For example, natural gas plants have become increasingly more efficient, thus humans are able to obtain more energy out of the same amount of gas.
Rapid population growth is detrimental to achieving economic and social progress and to sustainable management of the natural resource base. But there remains a sizeable gap between the private and social interest in fertility reduction, and this gap needs to be narrowed.
