Question

Explain the experimental determination of dielectric constant of dielectric material placed between capacitor plates by charging and discharging of a capacitor and hence derive an equation for dielectric constant
K=dT1/2÷
0.693EoAR​

Answer 1

Answer:

The Sun is a hot plasma (ion-

ized matter) with its inner core

at a temperature exceeding 107

K, and its outer surface at a

temperature of about 6000 K.

At these high temperatures, no

substance remains in a solid

or liquid phase. In what range

do you expect the mass density

of the Sun to be, in the range

of densities of solids and liquids

or gases? Check if your guess is

correct from the following data:

mass of the Sun = 2.0 x 10³⁰ kg,

radius of the Sun = 7.0 x 10⁸ m.
