<prompt> Bernoullis principle statesSum of kinetic energy of flow and pressure energy is constantLow tones producing maximal stimulation at apex of cochleaMagnitude of the sensation felt is proportionate to the intensity of stimulusForce of contraction is proportional to the stretch of cardiac muscle  <response>: Ans. a Sum of kinetic energy of flow and pressure energy is constantRef: Ganong, 25th edp.571Velocity of blood flow kinetic energy and the pressure potential energy are interrelated by the Bernoullis principleBernoullis principleStates that The sum of the kinetic energy of flow and the potential energy--is constantAccording to the principle, the greater the velocity of flow in a vessel, the lower thelateral pressure distending its walls to keep the total energy of the system constant
