At a specific depth in a swimming pool, a barometer measures the total pressure to be twice that of atmospheric pressure. If the barometer is now submerged to a depth that is twice its initial depth, by how much does the total pressure increase?
A. 50%
B. 100%
C. 200%
D. 300%
A) 50%
We can use the ratio technique to handle this percentage change type of problem. The relevant situation here is the relationship of pressure to depth:
Ptotal = Patm + ρgh
Applying this to the first depth...
