Period Between Heartbeats – The Physics Factbook
https://hypertextbook.com/facts/1998/PavelMatskevich.shtml
In order to obtain the period of the heartbeat is determined by the time between two consecutive heartbeats. The unit of time is seconds, and there is 60 seconds in each minute. The average heartbeat rate is 72 beats per minute. In order to get the value of the period number of seconds is divided by the number of beats.

what’s up everybody in this video I want to derive this formula right here this is the formula for beat frequency so remember the way you get beats or B frequency is by overlapping two waves that have different frequencies so when you do this you get beats and I’m not talking about dr. dre beats these are a little less exciting this is a sound wave that goes from being loud ie constructive to …

The beat frequency is equal to the absolute value of the differencein frequency of the two waves. Arising from simple interference, the applicationsof beats are extremely far ranging.

The closer the two sources are in frequency, the smaller the phase shift each cycle, so the more cycles you have to go through for the phase difference to reach 2Ï€ (or thereabouts). When the phase shift reaches that value, the two are in phase again. That completes one beat. what do you mean by The two are now slightly out of phase.

Amplitude, Period, Phase Shift and Frequency
https://www.mathsisfun.com/algebra/amplitude-period-frequency-phase-shift.html
The Period goes from one peak to the next (or from any point to the next matching point): The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2. The Phase Shift is how far the function is shifted horizontally from the usual position.

How to Calculate the Beats Per Minute (BPM) of a Song: 9 Steps
https://www.wikihow.com/Calculate-the-Beats-Per-Minute-(BPM)-of-a-Song
Multiply the number of measures by the number of beats per measure. After you turn off the stopwatch, count up how many measures you heard. Multiply this number by the number of beats in each measure to find out how many beats there are in 30 seconds.

Multiply your answer by 10. Because 6 seconds x 10 = 60 seconds, multiplying your answer by 10 will give you the number of heart beats that have occurred in one minute (in other words, the beats per minute, which is the standard measurement of heart rate).

There is one cycle from the zero at x = -Ï€/4 to the zero at x = Ï€/4. Hence the period P is equal to: P = Ï€/4 – (-Ï€/4) = Ï€/2 We now equate the value of the period found using the graph to the above formula and solve for b.

A lock-up period (also known as a lock-up agreement) is a period of time (usually between 90-180 days) when investors are not allowed to buy or redeem shares. Lock-up periods can apply to hedge funds and initial public offerings. A hedge fund lock-up period will be linked to the underlying investments of the fund.
