Quizplus · Accepted Answer

The gauge pressure at point A is determined by the height of the mercury column. The pressure is calculated using the formula P = ρgh, where ρ is the density of mercury, g is the acceleration due to gravity, and h is the height of the mercury column. Given the density of mercury and assuming standard gravity, the pressure is calculated to be approximately 4.41 kPa.
