The correct answer is 94.25 kg/s
Flux can be stated as the rate of flow of a fluid, radiant energy, or particles across a given area.
The magnetic flux is the magnetic lines present in among two magnets or solenoid is mutual flux.
Velocity is the count of difference in displacement in a given time and it is a vector quantity which has both magnitude and direction.
The mass of a sample of a chemical compound divided by the quantity, or number of moles in the sample, measured in moles, is known as the molar mass of that compound.
Given
density = 1.2 kg/m³
The velocity of the air is 94.25V kg/s
Assuming velocity of air through spherical shell = V m/s
Then flux = ρ *π * a² * V kg/s = 94.25V kg/s
Therefore, the velocity given will be 94.25V kg/s
