An object weights 20N in air and 16N in liquid then answer the following questions. a) what is the upthrust of the liquid on the objects? B) what is the weight of the displaced liquid? Write with reason.
Answers
Answer:
Archimedes' principle, the weight of the displaced liquid and the upthrust of the liquid on the objects are 4 N.
Explanation:
According to Archimedes' principle, a body submerged in a fluid, whether totally submerged or partially submerged, experiences an upward buoyant force equal to the weight of the fluid that the body displaces.
In this scenario, an object weighs 20 N in the air and 16 N when completely submerged in water. Thus,
20N - 16N = 4N
This is represented as the weight of the water that was displaced.
Therefore, the weight of the displaced liquid is 4 N
A body experiences an upthrust that is proportional to the weight of the body submerged and the volume of fluid displaced.
So, the upthrust of the liquid on the objects is 4N.
