Question

For the lab setup in part 1, if the speed of the wave on the string is determined to be 30.0 m/s, and 30.0 grams is hung from the end of the string, what is the mass density, mu, of the string (in grams/meter)? In a tube of air, the open end is a(n) ______ and the closed end is a (n) _____. In order for a standing wave to develop in a tube with one open and one closed end, the tube length needs to be at least a ________ wavelength. Select one: node, antinode, quarter antinode, node, quarter antinode, node, half node, antinode, half

Explanation / Answer

part a )

v = sqrt(T/mu)

T = mg

mu = mass density

v^2 = mg/mu

mu = mg/v^2

mu = 30 * 9.8 / 30^2 = 0.3267 g/m

part b )

b option
