What two forces limit the height to which capillary action will take water up a tube?
Jobisdone [24]
Capillary action<span> occurs when the adhesion to the walls is stronger than the cohesive</span>forces<span> between the liquid molecules. The </span>height to which capillary action will take water<span> in a uniform circular </span>tube<span> (picture to left) is limited by surface tension and, of course, gravity.

Hope this helps. :)</span>

One charge is decreased to one-third of its original value, and a second charge is decreased to one-half of its original value.
Nadya [2.5K]
The original Coulomb force between the charges is:

Fc=(k*Q₁*Q₂)/r², where k is the Coulomb constant and k=9*10⁹ N m² C⁻², Q₁ is the first charge, Q₂ is the second charge and r is the distance between the charges.

The magnitude of the force is independent of the sign of the charge so I can simply say they are both positive. 

Q₁ is decreased to Q₁₁=(1/3)*Q₁=Q₁/3 and
Q₂ is decreased to Q₂₂=(1/2)*Q₂=Q₂/2. 

New force:

Fc₁=(k*Q₁₁*Q₂₂)r², now we input the decreased values of the charge

Fc₁=(k*{Q₁/3}*{Q₂/2})/r², that is equal to:

Fc₁=(k*(1/3)*(1/2)*Q₁*Q₂)/r²,

Fc₁=(k*(1/6)*Q₁*Q₂)/r²

Fc₁=(1/6)*(k*Q₁*Q₂)/r², and since the original force is: Fc=(k*Q₁*Q₂)/r² we get:

Fc₁=(1/6)*Fc

So the magnitude of the new force Fc₁ with decreased charges is 6 times smaller than the original force Fc.

Elden [556K]

The election would be given to the members of the House of Representatives who would be able to select either O'Rourke, or Trump only, because they were the only candidates who received more than 15% of the available electoral votes.

<h3>What is the role of house of representative?</h3>

The house of representatives are those that has been given the authority to make and pass federal laws.

They are supposed to handle and mischief during elections that may affect the process on order to ascertain the rightful leader.

From the excerpt given, since a recount of the votes where made and the three parties involved had a miscount, the final decision should be made by the house of representatives.
