when sulfur burned in the presence of oxygen it produce sulfur dioxide. The sulfur dioxide can further react with oxygen to produce sulfur trioxide and then react with water to form sulfuric acid.
Uses of sulfur dioxde:
It is used as a solvent and reagent in laboratory.
Distance between the Tulsa, OK observatory and the center of this fictional earthquake: 20 kilometers.
An earthquake generates two major seismic waves that travel through the crest at different speeds:
Primary (P) waves travel at between 6 and 7
Secondary (S) waves travel at approximately 3.5 .
Let and denote the speed of the two waves, respectively. Let , resembles the time required for each waves to reach the observatory.
Both and would represent the separation between the source and the observatory. Thus
Given the difference between and :
( given that and )
Note that wave speed data involved in calculations above came from an external source. You shall repeat those steps with speeds indicated on the worksheet if possible.
