Answer:

б / 
Ф ( б /
)
Explanation:
<u>Develop a suitable set of dimensionless parameters for this problem</u>
The set of dimensionless parameters for this problem is :

б / 
Ф ( б /
)
and they are using the pi theorem, MLT systems
attached below is a detailed solution
It would increase
because the force is directly proportional to the Value of masses given
Answer:
a) 0.568 kg
b) 474 kg/m³
Explanation:
Given:
Inner radius = 8.82 cm = 0.0882 m
Outer radius = 9.91 cm = 0.0991 m
Density of the liquid = 948.00 Kg/m³
a) The volume of the sphere =
or
volume of sphere = 0.0012 m³
also, volume of half sphere =
or
volume of half sphere =
or
Volume of half sphere =0.0006 m³
Now, from the Archimedes principle
Mass of the sphere = Weight of the volume of object submerged
or
Mass of the sphere = 0.0006× 948.00 = 0.568 kg
b) Now, density =
or
Density =
or
Density = 474 kg/m³
