S Distinguish between real and apparent cubic
expansivities of a liquid.
A glass bottle full of mercury has mass 500 g
On being heated through 35°C, 2.43 g of
mercury are expelled. Calculate the mass of
mercury remaining in the bottle (cubic
expansivity of mercury is 1.8 x 10-4 per K
linear expansivity of glass is 8.0 x 10-6

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.
