A beaker weighs 0.4 Ñ when empty and 1.4N when filled with water. what does it weigh when filled with brine of density 1.2g/cm3.(density of water is 1.0g/cm3). ​

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.
