Pulse and pendulum According to his first biographer Viviani, Galileo experimented with synchronizing two clocks -- the human pulse, and a pendulum -- in his student days at Pisa. The resulting invention, the "pulsilogium", represented the pulse rate as the length of the pendulum. Try making a pulsilogium: adjust the length of a pendulum so that its rate of swinging agrees with your own pulse. Mark the length. Then adjust the same pendulum for your lab partner's pulse -- is there a detectable difference in pulse rate? 2. Pendulum length and frequency It would be good to know what pendulum length means as a frequency (or pulse rate). http://www.mtholyoke.edu/courses/mpeterso/galileo/time2.htm

What do you use to measure your pulse?
In order to measure your pulse you may use a watch or clock with a second hand. Make a note of the rate of the pulse, which is the number of beats per minute. Check the strength of the pulse to see if it is strong or weak and if the rhythm is regular or irregular.If you don't have a watch or a clock around, the Cleveland Clinic Health System recommends counting the beats you feel for 15 seconds and multiplying this by four to get your heart rate per minute: Check your pulse: _______________ (beats in 15 seconds) x 4 = ________________(your pulse)[1] You can count beats for 30 seconds and multiply by 2.
When you are counting pulse beats are you counting heartbeats?
Yes, your pulse is your heartbeat rate.
What is the Formula for simple interest rate?
The answer for rate in simple interest is =rate= simple interest\principle*time
What is the dependent variable in an experiment to determine whether drinking caffeinated soda increases pulse rate?
The pulse rate, since it's dependent on the quantity of caffeine, which is the changeable, independent variable.
Why is the emigration rate in Ireland higher than the immigration rate?
your pulse rate is higher because ur heart beats faster than what it breathes
