The lowest possible frequency that can form in a musical instrument is called the a fundamental frequency b the harmonic c the second harmonic d the last harmonic

The answer is A,

or fundamental frequency!

Hope this helps

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

what is the actual question though?
