You and a friend have some pvc pipes of various lengths and a hacksaw. You select a very long pipe that is open at both ends but your friend chooses a shorter pipe that is closed at one end. You want to cut your open pipe to a length that makes its no = 2 harmonic the same frequency as the closed-at-one-end pipe’s nc = 3 harmonic. If your friend’s pipe is 60 cm long, how long should you make your pipe? For the representation, draw a standing wave, then draw an open-at-both-ends pipe above the wave that is long enough to have the no= 2 harmonic wavelength match the standing wave’s wavelength and below the wave draw a closed-at-one-end pipe that is long enough to have the nc= 3 harmonic wavelength match the standing wave’s wavelength.

While listening to operatic solos, musicians process the lyrics and the tunes in separate brain areas. this most clearly illustrates the functioning of different

In the nineteenth century, gregor mendel first determined some basic rules of genetics that have been observed throughout all types of life. no observations have disproved these basic rules of genetics. charles darwin developed the idea of biological evolution around the same time, but he was unaware of mendel’s discoveries in genetics. over a century later, darwin’s idea of evolution was modified in order to incorporate mendel’s rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendel’s rules of genetics and darwin’s idea of biological evolution? a.)mendel’s genetics states laws that are now part of the theory of biological evolution.b.)biological evolution states laws that are part of mendel’s theory of genetics.c.)mendel’s genetics replaced darwin’s entire concept of biological evolution.d.)biological evolution is a law that explains why all genetics exist.
