I NEED HELP PLEASE, THANKS! :) If a musical instrument such as a trumpet or flute is “flat”, should the pipe be lengthened or shortened?

Shortened

Explanation:

A longer pipe will have a longer wavelength, and therefore a lower frequency.

A shorter pipe will have a shorter wavelength, and therefore a higher frequency.

A "flat" note has a low frequency, so the pipe should be shortened.

The same phenomenon can be demonstrated with guitar strings.  The longer the string, the lower the pitch.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
