Atuning fork, frequency 385/sec produces resources with a closed tube 20cm long and 4cm in diameter what is the speed of sound? [338m/s]

308 m/s

Explanation:

In a closed tube, the length of the tube (L) is related to the wavelength of the standing wave () by the relationship

In this problem, the length of the tube is L=20 cm=0.20 m, so we can find the wavelength of the standing wave:

And no we can find the speed of the sound wave by using the following equation:

where is the frequency of the wave. So, we find

the force on the thing and the distance the force moves the thing

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
