Consider the unsteady flow u = u_0, v = kt, w = 0, where u_0 and k are positive constants. show that the streamlines are straight lines, and sketch them at two different times. also show that any fluid particle follows a parabolic path as time proceeds.

the answer is 13 cm

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

step-by-step explanation:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
