| **Calculate the water pressure at the bottom of one of the deepest sea troughs in the Mariana depth which is 10900m and the density of seawater is 1030kg m3**

The hydrostatic pressure at the bottom of the Mariana Trench can be calculated using the formula:

Р = ρ * g * h, where ρ is the density of seawater (for salt water ρ = 1030 kg / m3), g is the acceleration of gravity (we assume g = 9.8 m / s2), h is the depth of the Mariana Trench (h = 10900 m).

Let’s calculate the water pressure:

P = ρ * g * h = 1030 * 9.8 * 10900 = 110024600 ≈ 110 MPa.

Answer. The seawater pressure at the bottom of the Mariana Trench is 110 MPa.
