Question

Define Viscosity. What are itsunits and

dimensions?6.Why are drops and

bubbles Spherical?​

Answer 1

Required Answer :-

1]Viscosity is defined as the amount of fluid that are required to flow in a resistor.

It's units are :-

n/s²

Where n = newton

s = second

But SI unit of Viscosity is different which is

pa/s

Where

pa = pascal

s = second

The dimension is

$\sf \boxed{ \sf ML^{-1}T^{-1}}$

2]The drops and bubbles are due to the attractive force of the surface.
