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.

moving ball hits still ball. mover stops, hit ball moves. momentum transfer.

momentum of soft ball three times less than baskey ball
