Alarge ant is standing on the middle of acircus tightrope that is stretched with tension t_s. the rope has mass per unit length mu. wanting to shake the ant off the rope, a tightropewalker moves her foot up and down near the end of the tightrope, generating a sinusoidal transverse wave of wavelength lambda and amplitude a. assume that the magnitude of the acceleration due to gravity isg. what is the minimum waveamplitude a_min such that the ant will become momentarily weightless atsome point as the wave passes underneath it? assume that the massof the ant is too small to have any effect on the wavepropagation. express the minimum wave amplitude interms of t_s, mu, lambda, and g.

Uranium has two naturally occurring isotopes. 238u has a natural abundance of 99.3% and 235u has an abundance of 0.7%. it is the rarer 235u that is needed for nuclear reactors. the isotopes are separated by forming uranium hexafluoride uf6, which is a gas, then allowing it to diffuse through a series of porous membranes. 235uf6 has a slightly larger rms speed than 238uf6 and diffuses slightly faster. many repetitions of this procedure gradually separate the two isotopes. what is the ratio of the rms speed of 235uf6 to that of 238uf6? express your answer to five significant figures.
