Question
1) A 52.0-kg woman wearing high-heeled shoes is invited into a home in which the kitchen has vinyl floor covering. The heel on each shoe is circular and has a radius of 0.520 cm. (a) If the woman balances on one heel, what pressure does she exert on the floor? _________________________N/m^2 ???? 11) The weight of a rectangular block of low-density material is 14.5 N. With a thin string, the center of the horizontal bottom face of the block is tied to the bottom of a beaker partly filled with water. When 25.0% of the block's volume is submerged, the tension in the string is 13.0 N. (a) Find the buoyant force on the block. _________________________ N ?????Explanation / Answer
Pressure = Force/Area If woman balances on one heel, pressure she exert on the floor=(52 x 9.81)/pi(.52x10^-2)^2 =6005038.43 pa buoyant force=14.5-13=1.5 N
