Question

the unit of impulse per unit area is same as that of

Answer 1

momentum per unit area
impulse=force * time             
force= momentum/time
impulse=momentum
impulse per unit area=momentum per unit area
pressure=force/area
force=impulse/time
impulse per unit area = pressure*time

Answer 2

Answer:

The unit of impulse per unit area is same as that of viscosity.

Explanation:

The unit of impulse per unit area is same as that of viscosity.

Viscosity is the force per unit area. Its dimensional formula is [M¹L⁻¹T⁻¹].

Dimensional formula of impulse is

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

Dimensional formula of impulse per unit area is

$I=\dfrc{[M^{1}L^{1}T^{-1}]}{[L^2]}$

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

The dimension formula of viscosity is $[M^{1}L^{-1}T^{-1}]$.

Hence, The unit of impulse per unit area is same as that of viscosity.
