Answer:
Water surface tension
Explanation:
The water around the paperclip forms a kind of elastic surface, deforming, in which the clip can stay afloat.
This is because the molecules that are on the surface of the water, already in contact with the air, try to cling to those that are next to them and those that are immediately below.
If we added even if it were just a drop of soap in the water, the clip would go to the bottom, because the soap has the ability to decrease the surface tension of the water.
Technician B I did this in my lesson and the right answer is B
This is all you need to mix body filler.
Start with a golf-ball size glob of filler.
Squeeze a ribbon of hardner across the filler.
Stir the mixture quickly, but do not "whip" it. ...
Mix until overall color is even.
Pick up an appropriate amount of filler for the task at hand.
I’m just here for points because I have test and I need them lol
Answer:
The attached system shows that there’s an integrator between the point where disturbance enters the system and error measuring element. A any time when R(s)=0 then
and considering that 
then
For ramp disturbance d(t)=at
therefore, the steady state error is given by
![e(\infty)= \lim_{s \to 0} s [\frac {D(s)}{1+G_c(s)G(s)}]](https://tex.z-dn.net/?f=e%28%5Cinfty%29%3D%20%5Clim_%7Bs%20%5Cto%200%7D%20s%20%5B%5Cfrac%20%7BD%28s%29%7D%7B1%2BG_c%28s%29G%28s%29%7D%5D)
![e(\infty)= \lim_{s \to 0} s [\frac {a}{s^{2}+s^{2}G_c(s)G(s)}]](https://tex.z-dn.net/?f=e%28%5Cinfty%29%3D%20%5Clim_%7Bs%20%5Cto%200%7D%20s%20%5B%5Cfrac%20%7Ba%7D%7Bs%5E%7B2%7D%2Bs%5E%7B2%7DG_c%28s%29G%28s%29%7D%5D)

Whenever 
has a double intergrator, the error 
becomes zero
