Question

A nurse counts 72 heartbeats in 1 minute. Show that the period and frequency of the heartbeats are 0.83 s and 1.2 Hz, respectively.

Answer 1

period = 0.833 s

frequency=1.2 Hz

Step-by-step explanation:

The period is the duration of time taken for a 1 heartbeat

`period=(1*60)/(72) \\=0.833 seconds`

Frequency is the number of heartbeats per second

`frequency=(72)/(60)\\ =1.2 Hz`
