*1. The direction of pressure is always perpendicular to surface area of a body emerged inside fluids. a. True b. False 12. In hydrostatic pressure apparatus, we make torque balance around the pivot between (applied weight * Length of balance arm) and (horizontal forces applied by water on quadrant distance from pivot to the center of these forces). a. True b. False 13. If the temperature of the liquid increased its viscosity will increase causing the balls to travel through the liquid faster. a. True b. False 14. In hydrostatic pressure apparatus, increasing temperature of the used water leads to a decrease in the level of water which is required to balance the same applied weight. a. True b. False 15. As the depth of immersion of a vertical surface increase, the location of the center of pressure comes closer to the center of gravity of the area. a. True b. False
