Question

Acelera tron 6+ 1B Eg DIOCE = GO15 = MIS 2 F=ma =Sx(60/15)-20N) 4. On a hot summer day (30 degrees Celsius), a pesky little mosquito produced its warning sound near your ear. The sound is produced by the beating of its wings rate of about 600 wing beats per second. What is the frequency in Hertz of the sound wave? What is the wavelength of the wave? (10 points)

Answer 1

second = 600 No.of beats =NO. of pen Ta 30°c , beats oo cycles per secondL No. As Frequency to =600 HZ EPO At nomal atmosphenic speed of soud wave through ain'iù tempenature dependance ain' is goven by psan pressure f V= 331 + Oo6 T

Here 331 m/s is Apeed at o°C and speed ofsound changes by 0.6m/s for every I chauge in temperatune. 'T' is 'the temperature :V=331+ 0.6(30) 349 mlS V= Also V=fd da 3491600 d=0.58m

Hope this helps...
