Incompressible. Compressibility is determine by the amount of space between particles in each state.
The electric field produced by a large flat plate with uniform charge density on its surface can be found by using Gauss law, and it is equal to
![E= \frac{\sigma}{2\epsilon_0}](https://tex.z-dn.net/?f=E%3D%20%5Cfrac%7B%5Csigma%7D%7B2%5Cepsilon_0%7D%20)
where
![\sigma](https://tex.z-dn.net/?f=%5Csigma)
is the charge density
![\epsilon_0](https://tex.z-dn.net/?f=%5Cepsilon_0)
is the vacuum permittivity
We see that the intensity of the electric field does not depend on the distance from the plate. Therefore, the strenght of the electric field at 4 cm from the plate is equal to the strength of the electric field at 2 cm from the plate:
Answer:
Positive ions, or cations.
Oxygen... Hope this Warner helps
All of them apply because they all are doing some thing to move
