Need a proper definition for:
-Earthing
-Resitivity
-Power of accomodation
Extra question: What is a white hole (in terms of space)?
:D

Answer:

Bro, my answer was deleted. So here we go again.

Earthing: the process in which a metallic body is connected to the earth wire which provides a low resistance conducting path for the current is called as earthing.

Resistivity: Resistivity is the physical property of a particular substance which is having particular dimensions. Moreover, resistivity is only proportional to the nature and temperature of the particular material.

Power of accommodation(your spelling's wrong): The ability of the human eye to adjust itself such that it can see objects which are nearby and faraway is called Accommodation. It primarily involves the lens and ciliary muscles. The ciliary muscles are capable of modifying the curvature of the lens and thereby affecting the focal length of the lens.

White hole: In theory, a white hole looks similar to a black hole, but instead of sucking matter in, a white hole pushes matter away.

Yeah! I guess we are sorted!!

And you can find me on Wattpad: PrestoBlackthorn

And you guessed right I'm not on insta *awkward*

True TGA!!

MARK ME AS BRAINLIEST *again....awkward!* GOOD LUCK :))

Earthing :

The process of Connecting the metallic body of an electrical appliance to the earth via a conducting wire is called as earthing of the appliance.

The earth wire is connected to a large metal plate buried deep inside the earth.

Earth wire provides a low resistance path for current in case of leakage of current.

Resistivity:

It is defined as the resistance offered by a cube of a material of side 1m when current flows perpendicular to its opposite faces.

Or

Resistivity or specific resistance of a conductor is defined as the resistance of the conductor of unit length and unit area of cross section.

Power of accomodation:

The ability of the eye to focus both near and distant objects, by adjusting its focal length is called accomodation of the eye.

Focal length can be changed with the help of ciliary muscles.

The above answer has the answer to your extra question.

P.S. You've already marked brainliest answer (I'm too late to answer)

P.p.s Atleast hit the thanks button ^^"
