Answer:
its an antique physics apparatus for demonstrating acoustic standing waves in a tube.
So the given value or the formula in getting the electric potential region of space is V=350/sqrt of x^2+y^2. So the given data is x and y is equals to 2.6 and 2.8. So in my calculation i came up with an answer of 91.6
Answer:
Zeros to the left of a decimal can be insignificant place holders, such as in 0.043 (two significant figures).
