Underwater acoustics (also known as hydroacoustics) is the study of the propagation of sound in water and the interaction of the mechanical waves that constitute sound with the water, its contents and its boundaries. The water may be in the ocean, a lake, a river or a tank. Typical frequencies associated with underwater acoustics are between 10 ...
The SOFAR channel (short for sound fixing and ranging channel ), or deep sound channel ( DSC ), [1] is a horizontal layer of water in the ocean at which depth the speed of sound is at its minimum. The SOFAR channel acts as a waveguide for sound, and low frequency sound waves within the channel may travel thousands of miles before dissipating.
A metal ion in aqueous solution or aqua ion is a cation, dissolved in water, of chemical formula [M (H 2 O) n] z+. The solvation number, n, determined by a variety of experimental methods is 4 for Li + and Be 2+ and 6 for most elements in periods 3 and 4 of the periodic table. Lanthanide and actinide aqua ions have higher solvation numbers ...

Frustrations are mounting across southeast Texas as residents enter a fourth day of crippling power outages and heat, a combination that has proven dangerous – and at times deadly – as ...
Preheat oven to 325°F. Generously grease and flour a 12-cup Bundt pan. Whisk together all-purpose flour, corn flour, and salt in a bowl. Beat granulated sugar and butter with an electric mixer on ...
“At the end of the day, one thing I know is that I can always look myself in the mirror when I trust my spirit, when I trust God, when I ask God, when I move to the beat of my own drum — I can ...
The method of image charges (also known as the method of images and method of mirror charges) is a basic problem-solving tool in electrostatics. The name originates from the replacement of certain elements in the original layout with fictitious charges, which replicates the boundary conditions of the problem (see Dirichlet boundary conditions ...
