34. A vertical dam has a semicircular gate as shown in the figure. Find the hydrostatic force against the gate. 2 m water level 12 m 4 mE1) When studying the formation of mountain ranges, geologists estimate the amount of energy (work) required to lift a mountain from sea level. Consider a mountain having a shape of a solid cone with the base radius R and the height H. Assuming the sea level is at the base surface of the mountain and all the material is lifted from the sea level, nd an expression of the total work required in forming the mountain. Assume the mass density of the mountain is uniform, denoted as p, and use the gravitational constant denoted as g
