Fluid mechanics example the prototype canoe is l = 6 m long and you have been asked to conduct a model study at 1/6th scale to estimate the drag force (fd) on the canoe when it is propelled at a velocity of 3.0 m/sec. your friend reminds you that they are pretty sure that the wave generation by the canoe is the dominant source of drag. i. what physical variables to you expect the canoe drag to depend on ? ii. express your above functional dependence in dimensionless form. iii. can total similarity be achieved (support your answer by demonstrating that it can or can not) ? iv. if you measure a drag force of 47 n in your lab study what is the prototype drag force ? v. what assumption(s) did you make in getting your answer to part (iv) ?

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
