Residents of Washington, D.C., and parts of Virginia were startled on Sunday afternoon by an explosive noise that reverberated overhead, which officials later confirmed was a sonic boom produced as United States
But how does the brain know where these vibrations occur? This is the organ of corti's job. The organ of corti is a structure containing thousands of tiny hair cells. It lies on the surface of the basilar membrane and extends across the length of the cochlea. Until a wave reaches the ...
Until a wave reaches the fibers with a resonant frequency, it doesn't move the basilar membrane a whole lot. But when the wave finally does reach the resonant point, the membrane suddenly releases a burst of energy in that area. This energy is strong enough to move the organ of corti ha...

How many decibels of sound does a wooden hockey stick produce when it is banged against a concrete floor? What is meant by resonance? What are the conditions for resonance to occur? Bats hear using . Describe how a wave is different from a pulse. ...
General relativity itself does not seem to allow a gravity propulsion system because that requires either too much energy or exotic forms of energy. But general relativity is not a quantum theory and thus not complete. See, every time a deeper theory of the universe is formulated, it doesn’...
A shock wave is a compression wave that, when produced in air, can usually be heard as a sonic boom. The speeds of supersonic objects are often expressed in terms of Mach number — the ratio of the object's speed to the speed of sound in the surrounding air. Thus, an object ...
