Starting from the general expression of the Navier-Stokes equations in cylindrical coordinates, provide the form of the equations for an axisymmetric, steady flow. Explicitly write down the continuity equation as well as the momentum equation in all relevant directions in terms of partial derivatives. (Hint: How much is uθ for this flow? Explain why. How much is ∂/∂θ ? IMPORTANT NOTE: Please have the answer complete, clear and computer generated!!

3. Consider the Cournot Duopoly model. a. Set up the model in general form using qi , qj instead of q1 , q2 b. Solve for the equilibrium quantity that each firm would produce. (This means as a function of exogenous variables - so not just the reaction functions.) c. Solve for the comparative static - how does each firm’s quantity change for a change in their own marginal cost and how does it change for a change in the...

(a) Derive a general expression for the energy difference between any two neighboring rotational state (i.e, the difference in energy between the L abd L+L states). (b) How does the energy difference change as L increases? (c) How does the energy difference change if the radius, r, of the rotating particle increases?
