(a)
To find: The volume of buoy
The volume of buoy is
Given information From the figure the radius of submerged cap is r and radius of buoy is
The volume of the buoy is
Substitute
This is the volume of buoy.
(b)
To find: The weight of buoy.
The weight of buoy
Given information From the figure the radius of submerged cap is r and radius of buoy is
The volume of the buoy is
Weight of the buoy=
Weight of the buoy=
Weight of the buoy=
(c)
To find: The weight of the displaced water.
The weight of displaced water is
Given information From the figure the radius of submerged cap is r and radius of buoy is
The volume of the buoy is
The volume of displaced water by sphere=volume of submerged cap=
The weight of the displaced water=
The weight of the displaced water=
(d)
To find: The depth of the buoy when it sinks.
Hence the depth is 0.254ft.
Given information From the figure the radius of submerged cap is r and radius of buoy is
The weight of the buoy is
The density of buoy is one fourth of the sea water.
Density of sea water is 1023.6kg/m3.
The density of the buoy is
Weight of the buoy=weight of displaced water
Solve the above equation the value of x is
X=2.8 gives
Hence the depth is 0.254ft.
