Aloaded flatbottom barge floats in fresh water. the bottom of the barge is 4.46 m below the water line. when the barge is empty the barge’s bottom is only 2.55 m below the water line. what is the difference between the pressure on the bottom of the loaded barge and the pressure at the water line?

The pressure difference between the pressure n the bottom of the loaded barge and the pressure at the water line is 18.73 KPa.

Explanation:

Bottom of the barge =4.46 m

When barge is empty,bottom= 2.55 m

We know that

Pressure P = ρ g h

Pressure difference

ΔP= ρ g Δh

ΔP= 1000 x 9.81 x (4.46-2.55) Pa

ΔP=18.73  KPa

So the pressure difference between the pressure n the bottom of the loaded barge and the pressure at the water line is 18.73 KPa.

yup its correct its: c) b b

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d
