A guitar string with mass density μ = 2.4 × 10-4 kg/m is L = 1.04 m long on the guitar. The string is tuned by adjusting the tension to T = 113.1 N. 1)With what speed do waves on the string travel? 2)What is the fundamental frequency for this string? 3)Someone places a finger a distance 0.164 m from the top end of the guitar. What is the fundamental frequency in this case?
A helium balloon ride lifts up passengers in a basket. Assume the density of air is 1.28 kg/m3 and the density of helium in the balloon is 0.18 kg/m3. The radius of the balloon (when filled) is R = 4.8 m. The total mass of the empty balloon and basket is mb = 120 kg and the total volume is Vb = 0.068 m3. Assume the average person that gets into the balloon has a mass mp = 71 kg...
