In an iceberg, 15% of the volume projects above the sea surface. If the specific weight of sea water is 10.5 kN/m^{3} , the specific weight of iceberg ir kN/m^{3} is

A reinforced concrete column contains longitudinal steel equal to 1 percent of net cross-sectional area of the column. Assume modular ratio as 10. The loads carried (using the elastic theory) by the longitudinal steel and the net area of concrete, are P_{s} and P_{c} respectively. The ratio P_{s}/P_{c} expressed as percent is
