Consider a 200-ft-high, 1200-ft-wide dam filled to capacity. Determine (a) the hydrostatic force on the dam and (b) the force per unit area of the dam near the top and near the bottom. Note: we will see that the resultant hydrostatic force will be

a)  

b)  

Explanation:

From the question we are told that:

Height

Width

a)

Generally the equation for Dam's Hydro static force is mathematically given by

Where

Therefore

b)

Generally the equation for Dam's Force per unit area is mathematically given by

For Top

For bottom

Therefore

a, c, d, e are all applying about success strategies.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
