Answer:
Δ P = 13.24 Pa
Explanation:
Given that
Density of oil ,ρ₁ = 9 x 10² kg/m³
We know that density for mercury ,ρ₂ = 13.6 x 10³ kg/m³
The change in the height of column ,Δh = 1.5 mm
The pressure given as
P = ρ g h
Change in the pressure
Δ P = ρ₁ g Δh
Now by putting the values
Δ P = 9 x 10² x 9.81 x 1.5 x 10⁻³ Pa
Δ P = 13.24 Pa
Therefor the change in the pressure will be 13.24 Pa.
A barometer measures atmospheric pressure.
