If the fundamental frequency of a cylinder is 310 Hz, and the speed of sound is 343 m/s, determine the length of the cylinder (in m) for each of the following cases. a. the cylinder is closed at one end
b. the cylinder is open at both ends.

a)  

b)  

Explanation:

From the question we are told that:

Frequency

Speed

a)

Generally the equation for Frequency is mathematically given by

The cylinder is closed at one end

b)

Generally the equation for Frequency is mathematically given by

the cylinder is open at both ends.

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.)

i wanna say it’s between b and d, leaning more towards b.
