Homework Answers
a) No.
Intensity = Power/Area
when we take any on the -x axis it is close to the source of sound placed at origin. an this source is power full.
so, at any point intensity due to the source placed at origin always greater.
b) yes.
when we take a point close to seond source, the intensities will be equal.
c) yes.
when we go away from second source at a particular pioint the two intensisties would be same.
d)
Let x is the distance from where the two intensities are same.
beyound second source.
I1 = I2
4*P/4*pi*x^2 = P/4*pi*(186 - x)^2
4*(186 - x)^2 = x^2
on solving the above equation we get,
x = 124 m and 372 m <<<<<------------Answer

Two sources of sound are located on the x axis, and each emits power uniformly in all directions. There are no reflections. One source is positioned at the origin and the other at x = +116 m. The source at the origin emits four times as much power as the other source. Where on the x axis are the two sounds equal in intensity? Note that there are two answers. xbetween the sources = xnot between the sources = Please...

A. Introduction and Objective Every test has at least two sources of variation that affect the results of the test. The first source of variation is due to the experimental procedure, such as using two different testing machines that have different calibrations, or different observers reading the same equipment differently. This type of variation is often called the experimental error The second source of variation is inherent in the specimens (or sample population) themselves. In other words, no two specimens...
