Question

The greatest ocean depths on earth are found in the Marianas Trench near the Philippines, where the depth of the bottom of the trench is about 11.0 km. Calculate the pressure due to the ocean at a depth of 9.1 km, assuming sea water density is constant all the way down.

Answer 1

To calculate the pressure due to the ocean at a depth of 9.1 km in the Marianas Trench, use the formula for pressure in a fluid and substitute the given values. Assume constant density of seawater all the way down.

Step-by-step explanation:

To calculate the pressure due to the ocean at a depth of 9.1 km, we can use the formula for pressure in a fluid:

Pressure = Density x gravitational acceleration x depth

Given the depth is 11.0 km, we need to calculate the pressure at 9.1 km. Since the density of seawater is assumed to be constant all the way down, we can use the same value for density. Substitute the values into the formula and calculate:

Pressure at 9.1 km = Density x gravitational acceleration x depth
