A cube of gold weighs 1.89N when suspended in air from a spring scale. When suspended in molasses, it appears to weigh 1.76 N. What is the buoyancy force acting on the cube? Do you think the buoyancy force would be greater or smaller if the gold cube were suspended in water?

A5 foot by 5 foot box culvert is buried 6 feet beneath the surface of the ground. a crosssection of this very long culvert (into and out of the page) is illustrated below. assume that the soil in which the culvert is buried has the following properties: jt = 120 pcf, w = 12%, ko = 0.50, ka = 0.33, and kp = 3.00. calculate the total horizontal force per unit length of culvert (fh) felt on one of the vertical faces of the culvert.
