Solve the Doppler Effect equation algebraically for the velocity of a sound, V. The sound source ismoving towards the listener.?=?

Sound intensity, B. in decibels (d B) is defined as B = 10 log(), where I is the intensity of the sound measured in watts per square metre (") and Io is 10-12 W, the threshold of hearing. Tracey decided that she needed a new vehicle, as her old one was beginning to run poorly and make extremely loud noises while the engine ran. When she got her new vehicle, she measured the relative sound intensities of the vehicles running and found that her old vehicle was 23 times as intense as the sound of her new vehicle. If the decibel level of her new car is 79 d B, what is the decibel level of the old car? Show your full solution method on your work sheet. In the answer field, express your answer to the nearest decibel. Answer:

2.4. The distance to the nearest antinode from the fixed end of a guitar string vibrating at its first harmonic is L, express this distance in terms of wavelength 2, i.e L = _A.

When poked by a spear, an operatic soprano lets out a 1047 Hz shriek. What is its wavelength (in m) if the speed of sound is 345 m/s? m Additional Materials O Reading

A guitar string is 0.9 m long with a mass of 0.0036 kg. The string is under 520 N of tension. a) What is the fundamental frequency of the string? b) What would be the fundamental frequency of the string it you doubled the tension?
