10.
The hydrostatic pressure exerted by a static homogeneous liquid of density rho at depth h beneath its free surface is expressed by:
P = rho * g / h
P = rho * g * h
P = rho * h / g
P = 1/2 rho * g * h2
11.
If a, b, c form a geometric sequence of positive real numbers, the geometric mean b equals:
b = a * c
b = a2 + c2
b = + sqrt(a * c)
b = (a + c) / 2
12.
In a hydraulic press, the ratio of the cross-sectional area of the large piston to that of the small piston is 50. If a force of 100 N is exerted on the small piston, the maximum force exerted by the large piston is:
5000 N
2500 N
