1.
Fluid as a continuum means
a.
continous distribution of mass.
b.
inter molecular distances are negligeable as
compare to thr system.
c.
adjesent to one molecule, there is another
molecule without any space.
d.
none of these.
2.
In solid deformation is important whereas in
fluid rate of defomation is important because
a.
the act of continous defomation is flow of
fluid.
b.
there is no elastic limit in fluid.
c.
fluid cannot regain their original condition
when applied force is removed.
d.
Fluid is act as continuum.
3.
What is viscosity?
a.
The property of
fluid which measures the friction of the fluid that applied on a solid
when it try to movie in that.
b.
The property of
fluid which measures the inter molecular forces between its molecules.
c.
The property of
fluid which measures hardness of fluid.
d.
The property of
fluid which measures the resistance of the fluid to the gradual
deformation due the shear stress.
