Consider a steady incompressible flow between two stationary, infinitely long and wide parallel plates. The distance between the plates is H. The flow is driven by a constant pressure gradient dP/dx. Derive the velocity profile for this flow and determine the constants from appropriate boundary conditions. Explain your assumptions.

What is the measurement of how fast an object moves relative to a reference point?

Write down two additional questions about earth's magnetic field that will make your presentation more informative.

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
