When a person inhales, air moves down the bronchus (windpipe) at 14 cm/s. the average flow speed of the air doubles through a constriction in the bronchus. assuming incompressible flow, determine the pressure drop in the constriction. (enter the magnitude.) pa?

The variables for this experiment include mass, volume and the materials in the various balls, as well as their densities. in part iii, you will be investigating the questionable baseball. use the drop-down menus to complete the sentences and identify the independent and dependent variables. in part iii, the independent variable, the one that is intentionally manipulated, is . in part iii, the dependent variable, the one that you measure the response in, is

Suppose you have three polarizing filters, with the second at an angle of 42∘ to the first and the third at an angle of 90∘ to the first. by what perfect will the original intensity of unpolarized light be reduced to after passing through all three filters?
