Explain the discrepancies between the experimental and theoretical results for the center of pressure.
Two pressure sensors are located at the seafloor: one is 100 m and the other is 500 m off the coastline. For a wave train of 10-s period, the pressure sensor closer to the shoreline measures the non-hydrostatic pressure amplitude as 5911 Pa and the other sensor measures the pressure amplitude as 4987 Pa. Given that the wave height is , what is the average bathymetric slope between the two pressure sensors? Take the magnitude of the gravitational acceleration as and the density of the seawater as . (Hint: Assume that the wave height has negligible variation between the two observation points.)

A spherical neutrophil 16µm in diameter is resting as shown in the attached photo. The pressure difference between the inside and outside of the cell is 7.5Pa. a) Draw free body diagrams of the whole cell and one hemisphere of the cell. b) Calculate cortical tension in the cell. In a micropipette aspiration experiment, a suction pressure of 52.5 Pa was used to aspirate the neutrophil membrane. c) Draw free body diagrams of the whole cell under micropipette aspiration and the portion of the cell in the micropipette. What is the diameter of the micropipette tip used to make this hemispherical projection? Next, the micropipette aspiration was stopped, and the cell was treated with Cytochalasin D, an inhibitor of actin polymerization, causing the cortical tension to decrease by half. d) Assuming the pressures inside and outside the cell have not changed, what is the new cell radius? e) If the same micropipette was used to aspirate the cell, what would be the new suction pressure?
