- Thanks! At the race track, one race car starts its engine with a resulting intensity level of 94.1 dB at point P. Then 5 more cars start their engines. If the other 5 cars each produce the same intensity level at point P as the first car, what is the new intensity level with all 6 cars running?What are the factors that determines loudness of a sound?#1: Why do guitar strings sound different when you pluck them, even though they are the same length?
- How can two different dog whistles operating at different frequencies be used to make sound audible to humans. I thought this would be to that if there is two different frequencies at high frequencies, when they subtract for us to get our beat frequency, a lower frequency would remain. But I don't think this is the correct answer. Thank you for the help.What is the difference between a transverse and longitudinal wave? List examples of each.-96 A listener detects a sound with an intensity of 2. 00 x 10° w/m.If the sound is generated at 80.0 W how far is the listener from the sound source? a) 631m
- The wavelengths of the sounds produced by two horns are 6.0 m and 7.0 respectively. What beat frequency is heard when the horns are sounded on a day when the velocity of sound is 336 m/s?#8Show how THREE different instruments (stringed instrument, air column closed at one end and an air column open at both ends) will resonate THREE different frequencies at room temperature, when speed of sound is approximately 340 m/s, with the same length of 0.46 m.
