Question

Human heart beats 75 times per minute.find its frequency and period

Answer 1

Hertz is synonymous with “cycles per second”. 75 beats/60 seconds = 1.25 beats per second which can be expressed as 1.25 Hz. The time period of the heart beat is an expression of seconds per beat (the duration of each heartbeat). 60 seconds/75 beats = 0.8 seconds per beat.
