Answer:
6.856ml/min/mmHg
Explanation:
We define the coefficient of filteration as Kf, which is a measure between the product of hydraulic conductivity and the surface area of the glomeruar capillatries. We can write it as,
Where is the Net filteration pressure,
Here we know as well that the Net filteration pressure is
Where
The hydrostatic pressure of capillaries
The oncotic pressure in capillaries
The hydrostatic pressure in bowman capsue
The oncotic pressure of ultrafilterate.
Kf=17.14 ml/min/mmHg of filteration pressure
Each kidney weighs 125 gm so both weigh 250gms.
Expressing it for per 100 gm of kidney:
Answer:
Hey
The rope isn't moving because each boy is pulling with the same force on opposite ends. That being said the bot pulling force is balanced.
Inside the rope are molecules connecting the whole thing together. The force they exert on each other must be equal because they aren't moving but are still exerting forces
Answer:
Option b. Effective nuclear charge increases as we move to the right across a row in the periodic table
Explanation:
The <em>effective nuclear charge </em>is a measure of how strong the protons in the nucleus of an atom attract the outermost electrons of such atom.
The <em>effective nuclear charge</em> is the net positive charge experienced by valence electrons and is calculated (as an approximation) by the equation: Zeff = Z – S, where Z is the atomic number and S is the number of shielding electrons.
The shielding electrons are those electrons in between the interesting electrons and the nucleus of the atom.
Since the shielding electrons are closer to the nucleus, they repel the outermost electrons and so cancel some of the attraction exerted by the positive charge of the nucleus, meaning that the outermost electrons feel less the efect of attraction of the protons. That is why in the equation of Zeff, the shielding electrons (S) subtract the total from the atomic number Z.
The <em>effective nuclear charge</em>, then, is responsible for some properties and trends in the periodic table. Here, you can see how this explains the trend of the atomic radius (size of the atom) accross a row in the periodic table.
- As the<em> effective nuclear charge</em> is larger, in a same row of the periodic table, the shielding effect is lower, the outermost electrons are more strongly attracted by the nucleus, and the size of the atoms decrease. That is why as we move to the right in the periodic table, the size of the atoms decrease.
