The north Celestial pole is 42.036 degrees above the northern horizon when I look at it from my front yard.
I don't need to know my latitude to discover that, since I can measure it directly in the sky.
But when I DO look up my latitude, it blows my mind ! It's the exact same number ... 42.036 degrees north ! This can't be just a coincidence. There must be some connection !
(YOU can't use this number. It's different where you live.)
Answer:
A
Explanation:
Density is mass/ volume
if the numerator is greater ( A) then the density is greater than B
The variable represented by that symbol is: d. Net force.
Answer:
4.81x10³ Ω*m
Explanation:
The resistivity (ρ) of the skin can be calculated using the following equation:
<u>Where:</u>
<em>R: is the electrical resistance of the skin = 500x10³ Ω</em>
<em>A: is the cross-sectional area of the skin</em>
<em>l: is the length of the skin= 1.6 m</em>
Since we can model the body between the hands as a cylinder, the cross-sectional area is:
Now, we can fin the resistivity (ρ) of the skin:
Therefore, the resistivity of the skin is 4.81x10³ Ω*m
