Everything that Julia said is correct EXCEPT the words
"the Oxygen and Hydrogen separate". They do not.
The "particles" that she mentioned are water molecules,
each one composed of two Hydrogen atoms and one Oxygen
atom bonded together. THOSE are the particles that shift to be
farther apart, but the Hydrogen and Oxygen in each one remain
bonded together.

Answer:
To find the diameter of the wire, when the following are given:
Resistivity of the material (Rho), Current flowing in the conductor, I, Potential difference across the conductor ends, V, and length of the wire/conductor, L.
Using the ohm's law,
Resistance R = (rho*L)/A
R = V/I.
Crossectional area of the wire A = π*square of radius
Radius = sqrt(A/π)
Diameter = Radius/2 = [sqrt(A/π)]
Making A the subject of the formular
A = (rho* L* I)V.
From the result of A, Diameter can be determined using
Diameter = [sqrt(A/π)]/2. π is a constant with the value 22/7
Explanation:
Error and uncertainty can be measured varying the value of the parameters used and calculating different values of the diameters. Compare the values using standard deviation
Tyrosine is an amino acid, which can be found in foods high in protein like eggs, meat, fish, beans and nuts. Amino acids are what make protein. Hope this helps!
Answer:
70.35%
Explanation:
The relative humidity is a percentage and is the ratio between the partial pressure of water and the vapor pressure of water times 100% The partial pressure gives you an idea of the amount of water in the air whereas the vapor pressure is related with the maximum amount of water that can be in the air for a given temperature.
Vp(h2o) -> Vapor pressure of water
p(h2o) -> Partial pressure of water
RH -> Relative humidity
Vp(h20) at 22°C = e^(20.386 - (5132 / (temperature + 273)) = 19.9 Torr
(1 Torr == 1 mm Hg)
RH = p(h2o)/Vp(h2o)*100% = (14/19.9)*100% = 70.35%
Note: The formula used to find the vapor pressure of water is an approximation, to get a better value you could use a table to determine the vapor pressure of water at a certain temperature. Remember that Vp(h2o) is a constant for a given temperature.
