Oscillation of a 260 hz tuning fork sets up standing waves in a string clamped at both ends. the wave speed for the string is 640 m/s. the standing wave has four loops and an amplitude of 3.1 mm.
(a) what is the length of the string?
(b) write an equation for the displacement of the string as a function of position and time. round numeric coefficients to three significant digits.

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
