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.)
The figure below shows a cylinder floating upright in a fluid. When the cylinderis displaced slightly along it’s vertical axis it will oscillate about it’s equilibriumposition with frequency, ω. Assume that this frequency is a function of thediameter, D, the mass of the cylinder, m, and the specific weight, γ, of theliquid.1. Determine, using the Buckingham Pi Method, how the frequency is relatedto these variables.2. If the mass of the cylinder were increased, would the frequency increaseor decrease?

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?

A certain amount of air is enclosed in a vertical cylinder of base surface A=100 cm2 by a frictionless piston of negligible mass. The height of the air column in the cylinder is h=50 cm. We carefully put a weight of mass m=14 kg onto the piston, and release it. The piston with the weight on it start an oscillating motion with small amplitude, which could be regarded as harmonic. Determine the amplitude and the frequency of the oscillation, as well as the maximal speed of the piston. (The wall of the cylinder can be considered a heat insulator. The external air pressure is p0=100 kPa) [Hint: dimensional analysis could be handy]
