Cell theory states that all living things are made of cells. And cells can only come from other cells, this disproves spontaneous generation and therefore proves the view that organisms can grow from food or dirt is wrong.

A square conducting plate 52.0 cm on a side and with no net charge is placed in a region, where there is a uniform electric fiel

Mrac [35]

Explanation:

Given: uniform electric field E= 82.0 kN/C.

a) charge density σ =ε_0 E.

therefore, $\sigma =82\times10^3\times3.85\times10^{-12}\\=0.0000003157= 315.7 nC/m^2$

b)Total charge on each face = σA

q=σA

$=315.7\times10^{-9}\times52\times10^{-4}\\=1.614\times10^{-9}= 1.614 \text{ nC}\\\text{Similarly on the other face } = -1.614 \text{ nC}$

Calculating ph how is ph related to the concentration of hydronium ions. True or False

Dmitry_Shevchenko [17]

I think this is TRUE. Ph is calculating the acidic acids in water. And you need to know the concentration of hydronium ions. Hope this helped !
