If a weight of 75 kN (Included in the 1,500-kN) is shifted a distance of 2.5 m to one side, it will cause the barge to go down 450 mm in the wdge of immersion and also rise 450 mm in the corresponding wedge of emersion The barge floats vertically (on an even keel) before the shifting of the weight.

- Global warming will produce rising sea levels partly due to melting ice caps and partly due to the expansion of water as average ocean temperatures rise. To get some idea of the size of this effect, calculate the change in length, Ah (in mm), of a column of water 1.5 km high for a temperature increase of 1.2 °C.Assume the column is not free to expand sideways. As a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to the surface can expand sideways onto land, and only to a limited degree. As another approximation, neglect the fact that ocean warming is not uniform with depth. Properties of water: 3 = 210 x 10 /C. c= 4186 J/kg - °C, L; = 334 kJ/kg, Le = 2256 kJ/kg Enter you answer below (to the nearest mm): Ah (in mm) = Type your answer.Find teh volume (m3) of teh water displaced for a wooden block of width 3.7 m and of depth D= 1.2 m, when it floats horizontally in teh water.
