(b) a lake is 5.0m deep the density of the water is 1000kg/m3 (i) calculate the pressure at the bottom of the lake due to the depth of water And the one under it I would appreciate the help thanks !

Given :

Density of the water, .

Depth of lake, d = 5 m.

To Find :

The pressure at the bottom of the lake due to the depth of water.

Solution :

We know, hydrostatic pressure is given by :

( Here,  g is acceleration due to gravity, g = 10 m/s².

Putting all values in above equation, we get :

Hence, this is the required solution.

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
