1) What is the average pressure on the soles of the feet of a standing 90.0-kg person due to the contact force with the floor? Each foot has a surface area of 0.0219 m2. kPa

2) The maximum pressure most organisms can survive is about 1000 times the atmospheric pressure. Only small, simple organisms such as bacteria can survive such high pressures. What then is the maximum depth at which these organisms can live under the sea (assuming that the density of seawater is 1025 kg/m3)? km

3) A nozzle of inner radius 1.08 mm is connected to a hose of inner radius 8.66 mm. The nozzle shoots out water moving at 25.0 m/s.
