The same force f with arrow is applied to the edge of two hoops. the hoops have the same mass, although the radius of the larger hoop is twice that of the smaller one. the entire mass of each hoop is concentrated at its rim, so the moment of inertia is i = mr2, where m is the mass and r is the radius. which hoop has the greater angular acceleration, and how many times as great is it compared to that of the other hoop?

Wo audio speakers are placed on a vertical rail. speaker a is placed at head-level while speaker b is place at some variable height, \delta yδy, above speaker a. both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.531 meters. calculate the lowest height that speaker b can be placed above speaker a to produce a minimum of sound heard by person standing \delta x = 7.86δx=7.86 meters directly in front of speaker a.
