Investigation The Weather Effects on The Sound Absorption Coefficients in Cinjar City
Journal Title: JOURNAL OF ADVANCES IN PHYSICS - Year 0, Vol 4, Issue 1
Abstract
In this work , the absorption coefficients A? had determined for different acoustic source by the air atmosphere for one day in Cinjar city, based on an analytical method which employed on several empirical equations that taking in consideration the various meteorological conditions in which the climate elements changed in additional to frequencies sources .The results shows the atmospheric absorption is sensitive to the composition of air , particularly to the wide varying concentration of water vapor and temperature where the air temperature play and frequency variation are dominate that controlling the values of A? .

An Explanation for the Equality between Inertia and Gravitational Mass
The mechanism causing the equality of inertia and gravitational mass of a body, which was demonstrated experimentally by Eotvos in 1909 is still unexplained although this equality is the basis of Einsteins General Theory...

The proposition that x = v t leads to a contradiction with Special Relativity
This short note posits the indisputable physical law prescribing that distance = velocity x time, and shows that this proposition contradicts Special Relativity, such that the above proposition is correct and Special Rel...
