Generally the unit used for frequency is Hertz (cycles per second).
Sound . . . 0.34 km/second Light . . . . 300,000 km/second
No, the speed of sound (at sea level) is only about 0.213 mile per second.
"ms" in this case is short for "meters per second". It means that sound advances that many meters every second.
the speed of sound is 1100 feet per second
when the ventricles closes and between the atria and the ventricles.
closure of the mitral and tricuspid valves.
Diastole is the phase in the cardiac cycle that allows filling of blood into the ventricle. It corresponds to the lower number in the blood pressure measurement. A normal upper limit of the blood pressure falls in the range less than 120/80 mm Hg. Above this value, it is considered pre-hypertension based on The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure.During the diastolic period the ventricle is in the fifth phase of the cardiac cycle. This phase is termed isovolumetric relaxation which occurs immediately after the second heart sound. In this phase, all valves of the heart are closed. The volume of blood in the ventricle during this phase of the cardiac cycle remains constant. Following the fifth phase of the cardiac cycle is the rapid filling of blood into the ventricle. This cycle corresponds to the opening of the mitral and tricuspid valves located between the left and right atria and ventricle, respectively. The next phase of the cardiac cycle, called diastasis, is the longest phase of the cardiac cycle. In this cycle, the ventricle continues to fill with blood but at a much slower rate. The final phase of diastole corresponds to the first phase of the cardiac cycle. In this phase of the cardiac cycle, the atria contracts to provide additional filling of blood into the ventricle. After the final phase of diastole, the systolic phase of the cardiac cycle begins.
The Y in cycle is a long I vowel sound, as the E is silent.
The basic unit of a frequency is called Hertz. One Hz is one cycle per second. This applies to frequencies such as sound, radio, and light.
A cycle in a sound wave is the time taken for one complete vibration.
Pulse (pulse = to beat) or Complete Cardiac Cycle (beginning of one heartbeat until the beginning of the next) are two medical term for "heartbeat". Listen to your heartbeat and you might distinguish two sounds. The first sound is the closing of the upper atrioventicular valves. The second sound is the closing of the semilunar valves. This is the pushing of the blood out of the heart. Between beats, the heart is filling with blood and preparing for another push or pulse.
In acoustic physics, "cycle" refers to the time between repetitions of the peak amplitude of the sound wave.
Generally the unit used for frequency is Hertz (cycles per second).
Sound waves reflect from objects. This is the echo. But a smooth surface and distance is required for this to occur. Sound moves at 343 meters per second in dry air at 20 degrees so if you make a sound and hear an echo 3 seconds afterwards the structure that reflected the sound is 1029 metres away. A distant wall, cliff, etc can act like a mirror to sound. Sound travels much slower than light ( 1715 metres in 5 seconds) so you get the sound wave back after a delay.

No, "second" and "blessing" do not rhyme. "Second" has an "eh" sound while "blessing" has an "i" sound.
