Voltage difference is the push that causes charges to flow from high to low areas.
Answer:
The weight of the objects has a name and is "Specific weight", this is measured in several measurements but the best known is the kg.
If we relate the density of the object with the weight we will obtain a deduction of the shape of the object.
Explanation:
The object can be more or less heavy according to its density and its chemical composition.The weight is nothing more than the attraction of that object with the interior of the earth, that is why in order to know well how heavy it is, it is necessary relate the density of the object, the material that composes it, the speed of gravity (10m / s2).
This refers to the fact that a kilo of feather is not the same as a kilo of lead, each object obtains its shape according to the more weight it has and the more attraction it can make to the center of the earth.

Answer:
The mass is ![m = 0.0349 \ g](https://tex.z-dn.net/?f=m%20%3D%20%200.0349%20%5C%20g)
Explanation:
From the question we are told that
The Henry's Law constant is ![k = 2.4 *10^{10} M/atm](https://tex.z-dn.net/?f=k%20%3D%202.4%20%2A10%5E%7B10%7D%20M%2Fatm)
The volume of water is ![V = 525 \ ml = 0.525 \ L](https://tex.z-dn.net/?f=V%20%3D%20525%20%5C%20ml%20%3D%200.525%20%5C%20L)
The partial pressure is ![P = 1.90 \ atm](https://tex.z-dn.net/?f=P%20%3D%20%201.90%20%5C%20atm)
The temperature is ![T = 25 ^oC](https://tex.z-dn.net/?f=T%20%20%3D%2025%20%5EoC)
Henry's law is mathematically represented as
Where C is the concentration of sulfur hexafluoride(SP)
substituting value
![C = 1.90 * 2.4*10^{-4}](https://tex.z-dn.net/?f=C%20%3D%201.90%20%2A%202.4%2A10%5E%7B-4%7D)
![C = 4.56*10^{-4} \ M](https://tex.z-dn.net/?f=C%20%3D%204.56%2A10%5E%7B-4%7D%20%5C%20M)
The number of moles of SP is mathematically represented as
![n = C * V](https://tex.z-dn.net/?f=n%20%3D%20C%20%2A%20V)
substituting value
![n = 0.525 * 4.56*10^{-4}](https://tex.z-dn.net/?f=n%20%3D%20%200.525%20%2A%204.56%2A10%5E%7B-4%7D)
![n = 2.39 *10^{-4} \ moles](https://tex.z-dn.net/?f=n%20%3D%20%202.39%20%2A10%5E%7B-4%7D%20%5C%20moles)
The mass of SP that dissolved is
![m = n * Z](https://tex.z-dn.net/?f=m%20%3D%20n%20%2A%20Z)
Where Z is the molar mass of SP which has a constant value of
![Z = 146 g/mole](https://tex.z-dn.net/?f=Z%20%3D%20146%20g%2Fmole)
So
![m = 2.394*10^{-4} * 146](https://tex.z-dn.net/?f=m%20%3D%20%202.394%2A10%5E%7B-4%7D%20%2A%20146)
![m = 0.0349 \ g](https://tex.z-dn.net/?f=m%20%3D%20%200.0349%20%5C%20g)
Answer:
The major ionic constituents whose concentrations can be determined from the salinity are known as conservative substances. Their constant relative concentrations are due to the large amounts of these species in the oceans in comparison t
