Q

Water depth in a dam is h, the wall's transverse area is A, and its thickness is t. Which combination determines hydrostatic pressure?

✓ Answer: D None of these
Pressure at depth h is ρgh, independent of wall area and thickness. None of the listed combinations states dependence on h alone for fixed fluid and gravity.
