Flux density of mass =( text Amount of mass / text Area × text time ) =([M]/[L2][T]) =[M L-2 T-1]

Q. The flux density of mass is defined as the amount of mass crossing unit area per unit time. The dimensions of this quantity is

$[M L^{- 2} T^{- 1}]$

$[M L^{2} T^{- 1}]$

$[M L T^{- 1}]$

$[M^{- 1} L^{- 2} T]$

Flux density of mass
$= \frac{Amount of mass}{Area \times time}$
$= \frac{[ M ]}{[ L ^{2} ] [ T ]}$
$= [M L^{- 2} T^{- 1}]$

Q. The flux density of mass is defined as the amount of mass crossing unit area per unit time. The dimensions of this quantity is

[ML−2T−1]

[ML2T−1]

[MLT−1]

[M−1L−2T]

Flux density of mass = Area × time Amount of mass ​ =[L2][T][M]​ =[ML−2T−1]

$[M L^{- 2} T^{- 1}]$

$[M L^{2} T^{- 1}]$

$[M L T^{- 1}]$

$[M^{- 1} L^{- 2} T]$

Flux density of mass
$= \frac{Amount of mass}{Area \times time}$
$= \frac{[ M ]}{[ L ^{2} ] [ T ]}$
$= [M L^{- 2} T^{- 1}]$
