Calculate the water pressure at the base of the hoover dam. the depth of water behind the dam is 210

As the unit of the depth is not mentioned, I will take it as 210 m.

The pressure exerted by a fluid of density ρ at depth h is given by,

P= P₀ + ρgh

here, ρ= density of water= 1000 kg/m³

g = acceleration due to gravity= 9.8 m/s

h= 210 m

P₀= atmospheric pressure at sea level = 101325 N/m²

Substituting the values,

P= 2159325 N/m²= 21.3 atm

Therefore, water pressure at the base of the hoover dam is 21.3 atm.

i think the answer is a, hope this is right, that would be my best guess.

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.
