Answer 1

The Correct answer is Hubble constant

Key Points:

'Expanding Universe'
- Edwin Hubble, an American astronomer, was the first to prove that the universe is expanding.
- According to Expanding Universe theory, the universe is presently expanding.
- Hubble proved that there is a direct relationship between the speeds of distant galaxies and their distances from Earth.
This is now known as Hubble’s Law.

Additional Information:Faraday:

When an electric current passes up to 1 second due to 96485 C, through an electrolyte then the equivalent weight of the electrolyte deposited is one & this amount of electric current is called 1 Faraday.
Faraday constant (F) = 96485C mol−1
The constant is named after the British physicist Michael Faraday.
It is a universal constant.
It is the amount of electric charge carried by 1 mole of electrons.
Represented by F & its measuring unit is Coulombs per mole (C.mol-1 ).
