Question

Which one of the following has no unit– (A) Force (B) Velocity (C) Acceleration (D) Relative density

Answer 1

I think Relative density is the answer dear..❤❤❤
Coz it is dimensionless quantity .
and dimensionless quantity have no unit.

Answer 2

$\red{HEY\:BUDDY!!}$

HERE'S THE ANSWER...

_______________________________

♠️ $\underline{Force}$

=> Force is product of mass and Acceleration , i.e

=> F = m × a

⏺️ SI unit of force [ kg m / s^2 ] OR [ Newton ( N ) ]

♠️ $\underline{Velocity}$

=> Velocity is ratio of displacement to the time , i.e

=> Velocity = displacement / time

⏺️ SI unit is [ m / s ]

♠️ $\underline{Acceleration}$

=> Acceleration is change in velocity with respect to time

=> Acceleration = ( v - u ) / t

⏺️SI unit is [ m / s^2 ]

♠️ $\underline{ Relative \:Density}$

=> It is the ratio of density of one medium to the density of another medium .

⏺️ It is the ratio of to same qualities so it has no SI unit Or we can say it is uniless ..

▶️ Answer is

=> $\blue{Relative \: Density}$
