Calculate the force a test charge of 0.001 coulomb would experience in the field across charged plates of 12 volts and separation of 0.6 cm.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
