The range of human hearing is roughly from twenty hertz to twenty kilohertz. Based on these limits and a value of 310 m/s for the speed of sound, what are the lengths of the longest and shortest pipes (open at both ends and producing sound at their fundamental frequencies) that you expect to find in a pipe organ?
What will be the vertical position of the boat. In the frame of reference of the truck, at what angle to the vertical does the boy throw can.
If the string is 9.5 long, has a mass of 30 and is pulled taut with a tension of 8.50, how much time does it take for a wave to travel from one end of string to the other?
