Scientists are beginning to develop the technology to observe other Sun-like stars distant from our solar system. They can even detect large Jupiter-like planets orbiting some of these stars. Other stars appear to have no planets, but astronomers can see the star wobble a bit in space. What do you think this means?

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.
