Calculate the first overtone in an ear canal, which resonates like a 2.40-cm-long tube closed at one end, by taking air temperature to be 37.0ºc. is the ear particularly sensitive to such a frequency? (the resonances of the ear canal are complicated by its nonuniform shape, which we shall ignore.)

Yes ear is sensitive to this frequency as it is

Explanation:

For first overtone the frequency is given as

here we know that

v = speed of sound in air

now we have

here

T = 37 degree C

now we have

now from above equation we have

now we have

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
