Anylon guitar string is fixed between two lab posts 2.00 m apart. the string has a linear mass density of μ=7.20 g/m and is placed under a tension of 160.00 n. the string is placed next to a tube, open at both ends, of length l. the string is plucked and the tube resonates at the n=1 mode. the speed of sound is 343 m/s. what is the length of the tube?

When can a theory be modified if a new type of technology allows for new observations that raise new questions? a-immediately, while the questions about the theory are being asked b-after new hypotheses related to the theory are tested in experiments c-only after the new observations disprove all parts of the theory d-while scientists begin to think about how the theory could improve
