A string is 2.4 m long, and the speed of sound along this string is 450 m/s. Calculate the frequency of the wave that would produce a first harmonic. Assume the string has nodes at both ends. What I've Tried Ln=2.4m v= 450 m/s f=? n=2 Ln=(4-1)/4 * Wavelen...

Name two solutions that can be used to precipitate out the following: PbCl2 Would I just use a random soluble compound and write a total ionic equation

Write an equation for a graph if period = 180, and amplitude = 6.. Given this information, is 6tanx not a proper answer? The back of the book says that the answer is 6sinx (2x)

A source passing a stationary observer is emitting a frequency of 560 Hz. If the speed of sound is 345 m/s, what must speed of the source be if the frequency speed is 480 hz? Here's what I've tried... Fo=480 Hz FObs = 480 + 560 VSource = ?(x) Vsound = 345...
