What is meant about di-electric constant?
The relative permittivity of a material is its dielectric permittivity expressed as a ratio relative to the permittivity of vacuum.Permittivity is a material property that expresses the force between two point charges in the material. Relative permittivity is the factor by which the electric field between the charges is decreased or increased relative to vacuum.Likewise, relative permittivity is the ratio of the capacitance of a capacitor using that material as a dielectric, compared to a similar capacitor that has vacuum as its dielectric. Relative permittivity is also commonly known as dielectric constant, a term deprecated in physics and engineering.
Can your electric get disconnected when the temperature is below freezing?
no
What is relative permitivity?
It is the element by which the electric field between the charges is diminished in respect to vacuum. In like manner, relative permittivity is the proportion of the capacitance of a capacitor utilizing that material as a dielectric, contrasted with a comparative capacitor that has vacuum as its dielectric.
Mentoin two special properties for uniformly charged spherical shell?
From Gauss's Law, Electric Field inside is 0, and it's electric flux is equal to Qenclosed/Eo, where Eo is the electric vacuum permittivity constant. Also, outside of the sphere, it could be treated as a point charge, where the point lies at the center of the shell and has a charge equal to the total charge of the shell.
What generates electricity as a result of temperature difference?
Thermoelectric devices create electric voltage from temperature differences.
What is difference between absolute permittivity and relative permittivity of medium?
The absolute permittivity of a medium is its relative permittivity multiplied by the vacuum permittivity. The absolute permittivity is a proportionality constant between the electric and displacement field with units of Farad/meters (in SI units). This number is usually very small (e.g. for air: 0.000 000 000 008 85 F/m). The relative permittivity is a unit-less number scaled upward to present nicer numbers (e.g. for air: 1.0005). To get the absolute permittivity from the relative permittivity one should multiply with the vacuum permittivity: 8.85418781... E-12 F/m.
What are Isotropic and Homogeneous Dielectric?
It is the same everywhere and in all directions.

How do you define gauss law-?
Gauss's Law states that the electric flux from a closed surface matches the amount of the enclosed charge divided by the permittivity.

What is the dimensional formula of permittivity of free space?
Permittivity =[Ɛo] = [Charge]2 /([Force] [Distance]2) =[TA]2 / [MLT-2] [L]2{[A] is the dimensional formula of electric charge} =[TA]2 / [ML3T-2] =[M-1L-3T(2+2)A2] = [M-1L-3T4A2]

When electromagnetic waves are moving through matter the speed of electromagnetic waves depends on?
Velocity of light in a medium depends on the electric and magnetic properties of that medium, namely permittivity, and permeability.
Why do we need to study light?
Light is a kind of energy which is sensed by eyes. Light is found to be electromagnetic wave whose velocity through space is decided by the magnetic and electric properties such magnetic permeability and electric permittivity. But the beauty is that the very space is relative.
How does the electrical force differ from gravity in its manifestation?
Electric force between electric charges where as the gravitational force is between the masses. Electric force is of two types both attractive and repulsive as like charges repel and unlike charges attract. But gravitational force is of only attractive. Electric force between electric charges. So the constant of proportionality has the electric permittivity property. But in case of gravitation, universal gravitation constant plays the equivalent role. It will be the same irrespective of the medium. In case of electric field, permittivity of the medium differ from each other. THe weakest force is the gravitational force where as the electric force would be comparativeley larger. Relatively moving electric field would bring magnetic field. But moving gravitational field does not produce any such field.
How do passive or active pickups work in the ukulele?
They use the piezo electric effect of certain crystals to capture the sound waves and resonance of the instrument.
How you can produce sound?
Some crystalline materials (quartz for example) resonate at ultrasonic frequencies when an electric field is applied to the material.
