Question

calculate the pressure at a depth of 50m below the surface of the sea. the density of seawater is 1024 kg per metre cube

Answer 1

Answer:

density = 1024 kg/m³

height = 50 m

gravity = 10 m/s²

answer is 512000 Pa

Explanation:

By using,

pressure = density x gravity x height.

pressure = 1024 x 10 x 50.

pressure = 512000 Pa

Answer 2

Given: The depth is 50m below the surface of the sea and the density of seawater is 1024 kg per metre cube.

To find: We have to find the pressure.

Solution:

To determine the pressure we have to use the below formula as follows-

P=dgh

Where P is the pressure.

d is the density of seawater which is equal to 1024 kg per metre cube.

h is the height which is equal to 50 meters.

g is the gravitational force which is equal to 10 meters per second square.

Putting the values in the above formula we get-

P=1024×10×50

P=512000

The pressure is 512000 Pa.
