publish date: 2026/05/20 22:35:59.807272 UTC
An anchor weighs \(100\text{ lb}\) in air. When submerged in water, it experiences an upward buoyant force of \(30\text{ lb}\). What is its apparent weight underwater, in pounds?
Answer = (1)
Correct Answer
(1) 70
Explanation
The apparent weight of an object submerged in a fluid is its true weight minus the upward buoyant force:
\[ \text{Apparent Weight} = 100\text{ lb} - 30\text{ lb} = 70\text{ lb} \]
