Answer:
blind person?
Explanation:
Because a blind person has difficulty with seeing.
The buoyancy is directly proportional to upthrust, therefore The buoyancy is equal to ρVg, where ρ is the water density, V is the object's volume and g is the acceleration due to gravity. In reality, buoyancy does vary due to the following effects: If the object is compressible then its volume V will reduce with depth, due to the increasing pressure.
Buoyancy is the force that pushes something up. When an object is immersed in water or other liquids, two forces act on it. That is, the object's weight pulls it down and buoyancy pushes it up.
The buoyancy of an object depends on the following factors: The volume of an object submerged in a fluid or liquid.; &The liquid or liquid density in which the body is immersed.
F_ {b} =-\ rho g V
F_{b}=buoyancy force
\rho=liquid density
g=gravitational acceleration
V=liquid volume
When a body is immersed in liquid it is called lift or buoyancy upward force. Its SI unit is Newton.
