Answer 1

$\huge\bold{\underline{\red{\mathrm{AnSweR}}}}$

one coulomb -

The coulomb is defined as the quantity of electricity transported in one second by a current of one ampere. Named for the 18th–19th-century French physicist Charles-Augustin de Coulomb, it is approximately equivalent to 6.24 × 1018 electrons. Coulomb. Quick Facts. International System of Units.

dielectric constant -

The relative permittivity, or dielectric constant, of a material is its permittivity expressed as a ratio relative to the vacuum permittivity. Permittivity is a material property that affects the Coulomb force between two point charges in the material.

Answer 2

Answer:

one coulomb:

The coulomb, also written as its abbreviation 'C', is the SI unit for electric charge. One coulomb is equal to the amount of charge from a current of one ampere flowing for one second. One coulomb is equal to the charge on 6.241 x 1018 protons. The charge on 1 proton is 1.6 x 10-19 C.

dielectric constant:

The relative permittivity, or dielectric constant, of a material is its permittivity expressed as a ratio relative to the vacuum permittivity. Permittivity is a material property that affects the Coulomb force between two point charges in the material.
