Answer:
1087.8 Pa
Explanation:
given that:
You fill a vertical glass tube to a depth of 15.0 cm with freshwater.
i.e Height (h₁) of the tube = 15.0 cm =0.15 m
Additional 15.0 cm of gasoline was added = 0.15 m
the density of the gasoline [tex]\rho_g[/tex] = 7.40×10² kg/m³ = 740 kg/m³
acceleration due to gravity (g) = 9.8 g
the gauge pressure at the interface between the gasoline and water can be determined as = [tex]\rho_g g h[/tex]
= 740 × 9.8 × 0.15
= 1087.8 Pa
Thus, the gauge pressure at the interface between the gasoline and water = 1087.8 Pa
