Re: Homework Help Thread - for all homework needs
Well yeah, you have to post questions
For example, if MAX doesn't get back to my halp request soon I'll post the question here.

Re: Homework Help Thread - for all homework needs
A 54-year survey of 26,285 European Swallows captured and released by the Avian Demography Unit of the University of Capetown finds that the average adult European swallow has a wing length of 12.2 cm and a body mass of 20.3 grams.
Because wing beat frequency and wing amplitude both scale with body mass, and flight kinematic data is available for at least 22 other bird species, it should be possible to estimate the frequency (f ) and amplitude (A) of the European Swallow by a comparison with similar species. With those two numbers, it will be possible to estimate airspeed (U). Species Body mass Frequency Amplitude European Swallow 20 g ≈ 18 Hz? ≈ 18 cm? By inverting this midpoint Strouhal ratio of 0.3 (fA/U ≈ 0.3), Graham K. Taylor et al. show that as a rule of thumb, the speed of a flying animal is roughly 3 times frequency times amplitude (U ≈ 3fA).5 We now need only plug in the numbers: U ≈ 3fA f ≈ 15 (beats per second) A ≈ 0.22 (meters per beat) U ≈ 3*15*0.22 ≈ 9.9 ... to estimate that the airspeed velocity of an unladen European Swallow is 10 meters per second.

Re: Homework Help Thread - for all homework needs
I need tutors.. Dedicated tutors.. Each weekday or every other weekday.. I need tutors for Math, Science, Language (English.. Has to be American, as I know how you foreigners like to add unnecessary 'U''s), and History.
Unlike the rest of my family, I want to graduate High School and get my Diploma instead of dropping out and getting my GED..
