The drag on a submarine moving below the free surface is to be determined by a test on a 1/19-scale model in a water tunnel. The velocity of the prototype in seawater (rho = 1015 kg/m3, v = 1.4 106 m2/s) is 1 m/s. The test is done in fresh water at 20C. Determine the speed of the water in the water tunnel for dynamic similitude and the ratio of the drag force on the model to the drag force on the prototype.

A retail company must file a monthly sales tax report listing the total sales for the month, as well as the amount of state and county sales tax collected. The state sales tax rate is 5 percent and the county sales tax rate is 2.5 percent. Write a Python program that asks the user to enter the total sales for the month. From this figure, your Python program should calculate and display the following:The amount of county sales taxThe amount of state sales taxThe total sales tax (county plus state)Use functions to calculate both the county and state sales tax amounts.
