Alarge water storage container is filled to a depth of 3.0 m. the volume above the water is filled with air. in order to pump the water from the container, the air pressure in the container is increased by 3.0 105 n/m2. what happens to the pressure in the water at a depth of 1.0 m when the air pressure is increased?

pressure at depth 1 m is 3.098 ×  N/m²

Explanation:

given data

depth = 3 m

air pressure = 3 × N/m²

to find out

pressure at depth 1  m

solution

we know air pressure is 3 × N/m²  so at pressure 1 m will be

pressure = air pressure + water pressure at 1 m    ............1

water pressure at 1 m is = ρ × g × h  

water pressure = 1000 × 9.8 × 1  

water pressure = 9800

so from equation 1

pressure = air pressure + water pressure at 1 m

pressure =  3 ×  + 9800

pressure = 3.098 ×

so pressure at depth 1 m is 3.098 ×  N/m²

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
