The due time is Central time. 001 (part 1 of 1) 10 points Find the speed of sound in tungsten, which has a bulk modulus of approximately 2 10 11 N / m 2 and a density of 19250 kg / m 3 . Answer in units of km / s. 002 (part 1 of 1) 10 points Some studies suggest that the upper fre- quency limit of hearing is determined by the diameter of the eardrum. The wavelength of the sound wave and the diameter of the eardrum are approximately equal at this up- per limit. If this is precisely true, what is the diameter of the eardrum of a person capable of hearing 21393 Hz? (Assume a body temperature of 36 . 2 C.) The speed of sound in air at 0 C is 331 m / s.
